    Electrical Bioimpedance Cerebral Monitoring: From Hyopthesis and Simulation to First Experimental Evidence in Stroke Patients2015Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Stroke is amongthe leading causes of death worldwide and requires immediate care to prevent death or permanent disability. Unfortunately, the current stateof stroke diagnosis is limited to fixed neuroimaging facilities that do not allow rapid stroke diagnosis. Hence, a portable stroke-diagnosis device could assist in the pre-hospital triage of patients. Moreover, such a portable device could also be useful for bedside stroke monitoring of patients in the Neuro Intensive Care Unit (Neuro-ICU) to avoid unnecessary neuroimaging. Recent animal studies and numerical simulations have supported the idea of implementing Electrical Bioimpedance (EBI) in a portable device, allowing non-invasive assessment as a useful tool for the pre-hospital triage of stroke and Traumatic Brain Injury (TBI) patients. Unfortunately, these studies have not reported any results from human subjects in the acute phase of the stroke. The numerical simulations are also based on simple models that sometimes lack necessary details.

    Finite Element Method (FEM) simulations on a realistic numerical head model as well as experimental Bioimpedance Spectroscopy (BIS) measurements from human subjectsin the acute, subacute and chronic phasesof stroke were used to answer the following research questions: (i) Does stroke modify the electrical properties of brain tissue in a way that is detectable via EBI? (ii) Would it be possible to detect stroke via EBI as early as in the acute and sub-acute phase?(iii) Is EBI sensitive enough to monitor changes caused by stroke pathogenesis?

    Using FEM to simulate electrical current injection on the head and study the resulting distribution of electrical potential on the scalp, it was shown that Intra-Cranial Hemorrhage (ICH) affects the quasi-symmetric scalp potential distribution,creating larger left-right potential asymmetry when compared to the healthy head model. Proof-of-concept FEM simulations were also tested in a small cohort of 6ICH patients and 10 healthy controls, showing that the left-right potential difference in the patients is significantly (p<0.05) larger than in the controls. Using bioimpedance measurements in the acute,  subacute and chronic phasesof stroke and examining simple features, it was also shown that the head EBI measurements of patients suffering stroke are different from controls, enabling the discrimination of healthy controls and stroke patients at any stage of the stroke. The absolute change in test-retest resistance measurements of the control group (~5.33%) was also found to be significantly (p<0.05) smaller than the EBI measurements of patients obtained 24 hours and 72 hours after stroke onset (20.44%). These results suggested that scalp EBI is sensitive to stroke pathogenesis changesand thususeful for bedside monitoring in the Neuro-ICU. These results suggested that EBI is a potentially useful tool for stroke diagnosis and monitoring.

    Finally, the initial observations based on a small number of patients, addressing the proposed future work of this thesis, suggested that the average head resistance amplitude of hemorrhagic stroke patients is smaller than in healthy controls, while ischemic stroke patients show a larger resistance amplitude than the controls. Scalp potential asymmetry analysis of healthy, hemorrhagic and ischemic stroke subjects also suggests that these three groups can be separated. However, these results are based on a small number of patients and need to be validated using a larger cohort. Initial observations also showed that the resistance of the EBI measurements of controls is robust between test and retest measurements, showing no significant difference (less than 2% and p>0.05). Subject position during EBI recording (supine or sitting) did not seem to affect the resistance of the EBI measurements (p>0.05). However, age, sex and head size showed significant effects on the resistance measurements. These initial observations are encouraging for further research on EBI for cerebral monitoring and stroke diagnosis. However, at this stage, considering the uncertainties in stroke type differentiation, EBI cannot replace CT but has the potential to be used as a consultation tool.

    Intracranial haemorrhage alters scalp potential distributions in bioimpedance cerebral monitoring applications: preliminary results from FEM simulation on a realistic head model and human subjects2016In: Medical Physics, ISSN 0094-2405, Vol. 43, no 2, p. 675-686Article in journal (Refereed)
    Abstract [en]

    Purpose:

    Current diagnostic neuroimaging for detection of intracranial hemorrhage (ICH) is limited to fixed scanners requiring patient transport and extensive infrastructure support. ICH diagnosis would therefore benefit from a portable diagnostic technology, such as electrical bioimpedance (EBI). Through simulations and patient observation, the authors assessed the influence of unilateral ICH hematomas on quasisymmetric scalp potential distributions in order to establish the feasibility of EBI technology as a potential tool for early diagnosis.

    Methods:

    Finite element method(FEM) simulations and experimental left–right hemispheric scalp potential differences of healthy and damaged brains were compared with respect to the asymmetry caused by ICH lesions on quasisymmetric scalp potential distributions. In numerical simulations, this asymmetry was measured at 25 kHz and visualized on the scalp as the normalized potential difference between the healthy and ICH damaged models. Proof-of-concept simulations were extended in a pilot study of experimental scalp potential measurements recorded between 0 and 50 kHz with the authors’ custom-made bioimpedance spectrometer. Mean left–right scalp potential differences recorded from the frontal, central, and parietal brain regions of ten healthy control and six patients suffering from acute/subacute ICH were compared. The observed differences were measured at the 5% level of significance using the two-sample Welch t-test.

    Results:

    The 3D-anatomically accurate FEM simulations showed that the normalized scalp potential difference between the damaged and healthy brainmodels is zero everywhere on the head surface, except in the vicinity of the lesion, where it can vary up to 5%. The authors’ preliminary experimental results also confirmed that the left–right scalp potential difference in patients with ICH (e.g., 64 mV) is significantly larger than in healthy subjects (e.g., 20.8 mV; P < 0.05).

    Conclusions:

    Realistic, proof-of-concept simulations confirmed that ICH affects quasisymmetric scalp potential distributions. Pilot clinical observations with the authors’ custom-made bioimpedance spectrometer also showed higher left–right potential differences in the presence of ICH, similar to those of their simulations, that may help to distinguish healthy subjects from ICH patients. Although these pilot clinical observations are in agreement with the computer simulations, the small sample size of this study lacks statistical power to exclude the influence of other possible confounders such as age, sex, and electrode positioning. The agreement with previously published simulation-based and clinical results, however, suggests that EBI technology may be potentially useful for ICH detection.

    Fyrtio år i vänsterfil2009Conference paper (Other academic)
    Abstract [sv]

    Detta paper är en förkortad och något omarbetad version av historiekapitlet i Bibliotek i Samhälles (BiS) jubileumsbok En ny förening är nödvändig (2009). Boken som har mer än trettio författare, ger en mångfacetterad bild av föreningen och tidskriften bis under de första fyrtio åren. De första åren i föreningens historia var intensiva, inte bara vad gällde den interna debatten. Massmedia var intresserade och föreningens uttalanden och aktioner fick stor uppmärksamhet. Framförallt var det kraven på en vidgad målsättning för folkbiblioteken, kritiken av SAB och av förslaget till ny bibliotekarieutbildning, som kommenterades i massmedia, för det mesta i positiva ordalag. Det viktigaste för BiS både då och nu är att bredda bibliotekets sociala bas, att nå nya grupper med bibliotekets alltmer omfattande service, så att en ökad satsning, eller neddragning, på folkbibliotek inte leder till fördjupare kunskaps- och kulturklyftor. BiS har fungerat som en så kallad tankesmedja, redan innan detta begrepp blev allmänt förekommande. Sammanfattningsvis kan man efter alla dessa år och återkommande debatter konstatera att det är just den socialistiska grundtanken om än vag och odefinierad som hållit samman föreningen.

    Hemma bra men borta bäst?: En jämförelse mellan inshoring och nearshoringför hållbara företag2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background and problematisation

    During the 1990’s many companies moved their production to remote low cost countries to reduce their production costs and create an increased competitive advantage. Research has now shown that this trend is reversing and companies are now starting to move their production to their home country or a close by low cost country due to the revelation that the total cost did not increase. Placing the production in or near the home country can result in a lower total cost, reduced risks and an increase of value to the consumer. The production location choice can also strongly be influenced by the companies’ sustainability work. The majority of research is focused around the comparison of Sweden and a low cost country in Asia but very little research has been done comparing Sweden and Europe.

    Purpose and method

    The purpose of the study is to compare the strategies inshoring and nearshoring by investigating Swedish sustainable micro companies’ choice of production location. To compare the strategies we will evaluate these through the factors cost, risk and value. The empirical material will be collected through semi-structured interviews with companies producing in either Sweden or Portugal. The result will then be analysed and connected to the theoretical framework around Supply Chain Management, sustainability and the three factors above to answer our research questions.

    Result and conclusion

    After the empirical data had been analysed we saw that the companies more or less shared there searchers’ views on that a production in Sweden in many ways was more cost effective, less prone to risks and increased the value to the consumers due to the brand being perceived as more sustainable. Also the design of the product played a big part in the choice of production location, something the literature did not bring up. Our conclusion was that none of the sourcing strategies were considered the best, but the size of the company, product design and the choice of material affected which production country that was deemed the most suitable.

    Vad är det som händer?: Upplevelser hos de anställda på ett sjukhusbibliotek vid en organisationsförändring2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to examine how organizational change is experienced by a group of librarians at a medical library. The main focus is the librarians’ own experience of this change. The change consists of making the medical library a fully digital library with strictly work related materials. Prior to the change the library was used as a public library as well as a medical library, with a variety of literature and quite a large physical space.

    To find out how the organizational change was experienced by the librarians the study uses qualitative semi-structured interviews as method. When analyzing the interviews the theoretical framework of Cullberg's crises theory is used.

    The results show that there have been a lot of crises experienced. Though there are individual differences in how much these crises are experienced by the respondents. The study’s conclusion also shows that there could have been a lot less crises experienced by the librarians if the organizational change would have been differently managed. The results in this study could be used by other library organizations in similar situations.

    Engagerat ledarskap och allas delaktighets betydelse för välmående: Kvantitativ studie kring välmående inom byggbranschen2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna studie bygger på teorier kring positiv psykologi och flourish (blomstring). Målet med positiv psykologi och blomstring handlar om att uppnå höga nivåer av lycka, mening och tillfredsställelse. Grundtanken med blomstring är att alla individer ska uppnå en hög nivå av mentalt välmående. Studien som följer utfördes på ett anläggningsföretag med syftet att undersöka om det finns några samband mellan de anställdas välmående och variablerna ’engagerat ledarskap’ och ’allas delaktighet’. Studien kommer också att innefatta en jämförelse mellan yrkesarbetares och tjänstemäns upplevelse och syn på välmående. Detta utfördes med hjälp av en enkätstudie uppdelad i två delar med två olika mätverktyg där första delen mätte välmående och andra delen de oberoende variablerna ’engagerat ledarskap’ och ’allas delaktighet’. Datainsamlingen skedde delvis elektroniskt och även ute i produktionen. Bland annat användes PERMAH-modellen som ett mätverktyg vid insamlingen av den empiriska datan. Analysen av empirin skedde genom ett utförande av ett t-test och regressionsanalyser i statistikprogrammet SPSS. Här jämfördes välmåendet mellan yrkesarbetare och tjänstemän och de oberoende variablernas betydelse för välmåendet. Resultatet visade att ’allas delaktighet’ hade störst betydelse för välmående i båda yrkesgrupperna men inget av resultaten var statistiskt signifikanta. I diskussionen resoneras det kring huruvida andra indexvariabler kunde gett ett tydligare och eventuellt statistiskt signifikant resultat. Den låga urvalsstorleken tas också upp som en bidragande faktor till det osäkra resultatet.

    Incidence of EMS-treated out-of-hospital cardiac arrest in Europe.2005In: Resuscitation, ISSN 0300-9572, E-ISSN 1873-1570, Vol. 67, no 1, p. 75-80Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The potential impact of efforts in Europe to improve survival from out-of-hospital cardiac arrest is unclear, in part, because estimates of incidence and survival are uncertain. The aim of the investigation was to determine a representative European incidence and survival from cardiac arrest in all-rhythms and in ventricular fibrillation treated by the emergency medical services (EMS). METHODS AND RESULTS: We used Medline to identify peer-reviewed articles published between 1 January 1980 and 30 June 2004 that reported a European community's EMS cardiac arrest experience. Inclusion criteria required the study to include at least 25 cases, report of the total number of all-rhythm and/or ventricular fibrillation arrests, and information about population size and study duration. The incidence was computed by dividing the total number of events by the product of the community's population and the study duration. Reports from 37 communities met the inclusion criteria. A total of 18,105 all-rhythm EMS-treated cardiac arrests occurred during 48 million person-years of observation, resulting in an overall incidence for all-rhythm arrests of 37.72 per 100,000 person-years. Incidence of ventricular fibrillation arrest was 16.84 per 100,000 person-years. Survival was 10.7% for all-rhythm and 21.2% for ventricular fibrillation cardiac arrest. Applying these results to the European population, approximately, 275,000 persons would experience, all-rhythm cardiac arrest treated by the EMS with 29,000 persons surviving to hospital discharge. CONCLUSION: The results provide a framework to assess opportunities and limitations of EMS care with regard to the public health burden of cardiac arrest in Europe.

    Fukttillstånd i olika ytterväggar med tre olika fasadsystem: En parameterstudie med Wufi2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A large number of buildings built under “miljonprogrammet” is today in need of renovation. With their high energy consumption it is also considered profitable to improve the buildings energy efficiency e.g. by additional insulation. It is however important to thoroughly evaluate potential damp issues that might arise as a result of these improvements before starting to implement a new building exterior.The aim of this study was to investigate three different façade systems based on how their moisture content and risk for mould growth are affected by different moisture loads, orientation, and additional insulation. Included is also a performance evaluation for each building exterior solution mounted on existing structure of wood, lightweight concrete and concrete structure. Damp simulations were done with the program Wufi and the results were then analysed by comparison to RF-curves in combination with risk assessments of the growth of mould with “Wufi Bio”.The overall conclusion shows that leakage due to torrential rain poses a great strain on building exterior systems. A solutions damp proof quality is largely dependent on its ability to withstand leakage from outer sources.The study also shows that a well ventilated cavity wall, sufficient drainage or a construction of exclusively vapour open materials has a positive impact on the amount of leakage.

    Bibliotek och unga vuxna: En undersökning av arbetet och profilen hos två unga vuxenavdelningar2015Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of this thesis is to examine how two young adult departments at two public libraries work and what profiles the young adult departments have. To examine the work and profiles at the young adult departments I have used the following questions: What are the ideas about working with young adults? How are the two departments in this study working whit young adults? What or which are the profiles of the young adult departments in this study?To answer the questions above I used a qualitative method based on interviews with the librarians responsible for the young adult departments. To complete the interviews I studied the libraries Internet sites and official documents. The examined departments are located at two city libraries and were chosen manly for their focused age group, 15-25 years and that the departments are well established.To analyse the results I used the theoretic model of Marianne Andersson and Dorte Skot-Hansen about the role of the public library. The model describes library profiles from four perspectives: the library as a cultural centre, a knowledge centre, an information centre and a social centre. I also used previous studies about the work with young adults at public libraries to analyse the results from the empiric studies.The analytical findings show many similarities in young adult services between theory and my study. Marketing, user treatment, user influence, the selection of activities and media and finally co-operation are the five categories in which the libraries focus their work with young adults. This is according to the results from my study and previous studies. The results from the analysis of the departments profiles show that the departments have traces from three of the categories but the main profile of both departments are the departments as a cultural centre.

    Förfrågningsunderlag: och dess betydelse som kvalitetsindikator för hemtjänst2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Lagen om valfrihet (LOV) infördes bl.a. för att underlätta för fler att starta egna företag inom vård och omsorg, men också för att samhällets medborgare skulle se en ökning av kvalité i utförandet av dessa tjänster. Kommunerna har ansvaret för socialtjänsten och genom att införa LOV ger de uppdraget vidare till en privat utförare. De kvalitetskrav för dem som ansöker om att starta hemtjänst, har kommunerna beskrivit i sina förfrågningsunderlag (FFU).

    Avsikten med studien är att få en bild av hur kommunerna säkerställer en god kvalitet inom hemtjänsten med hjälp av FFU och hur kraven i FFU följs upp. För att få en inblick i hur det kan se ut, sammanställdes kraven i FFU från tio kommuner och med hjälp av tre intervjuer med LOV ansvariga påvisas att kraven som ställs i FFU är olika mellan kommunerna. Kvalité är ett ord vars innebörd är svårfångat och har olika betydelser för olika individer. Samtidigt framgår det att det är ett komplext arbete att följa upp de krav som ställs i FFU och att det är få av kraven som kommunerna följer upp genom att ange uppföljningsmetod i FFU.

    Många kommuner har idag lokala värdegrundsgarantier för att beskriva vilka etiska värden som präglar äldreomsorgen och vad de äldre kan förvänta sig, olika ”löften” som utlovas till medborgarna. Garantierna är dock väldigt olika mellan kommunerna och är många gånger svåra att finna i FFU. I vår diskussion tar vi upp vilka möjligheter kommunen har att följa upp kvalitet i verksamheter som lagts ut på privata aktörer.

    Vår slutsats är att förfrågningsunderlagens betydelse som en kvalitetsindikator kan ifrågasättas.

    En gemensam europeisk historia?: Möjligheter och utmaningar för undervisning i historia.2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med den här studien är att undersöka den forskningsdebatt som finns kring möjligheter och utmaningar med en gemensam europeisk historia och ett gemensamt europeiskt perspektiv i historieundervisningen. Möjligheter och utmaningar med ett gemensamt europeiskt perspektiv på historien undersöktes genom kvalitativ textanalys av utvalda publikationer ur Europarådets material. De undersökta publikationerna omfattar seminarieredogörelser, rapporter från konferenser och material från utvärderingsseminarier kring projekt som strävar efter att konstruera en gemensam europeisk historia.Undersökningen visar på att det finns flera gemensamma värden som kan fungera som en grund för att konstruera en gemensam europeisk historia. Exempel på sådana värden är mänskliga rättigheter, demokrati, rättsstaten och respekt för människolivet. Likheter och skillnader bör redogöras för vilket gör det svårare att enas kring en gemensam europeisk historia.Vidare är det tydligt att de nationella identiteterna och historierna är starkare än den gemensamma europeiska historien. För att åstadkomma ett gemensamt europeiskt perspektiv på historien är det viktigt att lärarna är välutbildade. Historia, och därmed ett gemensamt europeiskt perspektiv, inte bör missbrukas för att konstruera falsk enighet eller splittring och hat mellan olika länder och grupper. Eurocentrism finns men går att motverka.Den gemensamma europeiska identiteten kan hota de nationella identiteterna men det är inte självklart eftersom alla kulturer är beroende av interaktion med andra kulturer för att skapas och utvecklas. Däremot förekommer användning av islam för att visa på vad som är europeiskt och vad som inte är det. Möjligheter och utmaningar med en gemensam europeisk historia behandlas i studien.

    Skrivande i en värld med digitala verktyg.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Med användning av informations- och kommunikationsteknik i skolans värld följer både möjligheter och utmaningar i undervisningen. Från att penna och papper har dominerat skrivundervisningen börjar skrivande på iPads och datorer bli allt vanligare. För att pedagoger ska kunna inkludera IKT i skrivprocessen är det viktigt att förutsättningar för det finns på skolan. Tekniska resurser samt teknisk IT support är en del av de förutsättningar som behöver finnas på skolan, men även kompetens om IKT hos läraren själv är en viktig del i skrivundervisning med digitala verktyg.SyfteSyftet med denna studie är att undersöka lärares uppfattningar kring fördelar respektive nackdelar med informations- och kommunikationsteknik i skrivprocessen i ämnet svenska.MetodI denna studie har kvalitativ metod i form av intervju använts för att undersöka pedagogers uppfattningar om inkluderandet av informations- och kommunikationsteknik i skrivprocessen. Studien utgår från en hermeneutisk tolkning eftersom avsikten var att undersöka respondenternas erfarenheter.ResultatResultatet visar att pedagoger resonerar kring både möjligheter och begränsningar i arbetet med IKT i skrivprocessen. Möjligheterna med IKT riktar sig framförallt mot elever med skrivsvårigheter; på vilka sätt de digitala verktygen kan främja skrivandet för dem. Vad gällande utmaningar diskuterar pedagogerna också i vilken utsträckning skrivande på iPad och dator hämmar utvecklandet av handmotoriken. Pedagogerna resonerar dessutom kring ytterligare möjligheter med de digitala verktygen men att kompetens för att använda dessa är viktigt att erhålla som lärare för att det ska fungera. Pedagogerna ser flera begränsningar med användandet av IKT såsom distraktion och svårighet att upptäcka stavfel.

    Aim To describe (a) changes in the organisation of training in cardiopulmonary resuscitation (CPR) and the treatment of cardiac arrest in hospital in Sweden and (b) the clinical achievement, i.e. survival and cerebral function, among survivors after in-hospital cardiac arrest (IHCA) in Sweden. Methods Aspects of CPR training among health care providers (HCPs) and treatment of IHCA in Sweden were evaluated in 3 national surveys (1999, 2003 and 2008). Patients with IHCA are recorded in a National Register covering two thirds of Swedish hospitals. Results The proportion of hospitals with a CPR coordinator increased from 45% in 1999 to 93% in 2008. The majority of co-ordinators are nurses. The proportions of hospitals with local guidelines for acceptable delays from cardiac arrest to the start of CPR and defibrillation increased from 48% in 1999 to 88% in 2008. The proportion of hospitals using local defibrillation outside intensive care units prior to arrival of rescue team increased from 55% in 1999 to 86% in 2008. During the past 4 years in Sweden, survival to hospital discharge has been 29%. Among survivors, 93% have a cerebral performance category (CPC) score of I or II, indicating acceptable cerebral function. Conclusion During the last 10 years, there was a marked improvement in CPR training and treatment of IHCA in Sweden. During the past 4 years, survival after IHCA is high and the majority of survivors have acceptable cerebral function.

    In-hospital cardiac arrest--an Utstein style report of seven years experience from the Sahlgrenska University Hospital.2006In: Resuscitation, ISSN 0300-9572, E-ISSN 1873-1570, Vol. 68, no 3, p. 351-358Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: In-hospital cardiac arrest is one of the most stressful situations in modern medicine. Since 1997, there has been a uniform way of reporting - the Utstein guidelines for in-hospital cardiac arrest reporting.MATERIAL AND METHODS: We have studied all consecutive cardiac arrest in the Sahlgrenska University Hospital (SU) between 1994 and 2001 for who the rescue team was alerted in all 833 patients. The primary endpoint for this study was survival to discharge.RESULTS: Thirty-seven percent survived to hospital discharge. Among patients who were discharged alive, 86% were alive 1 year later. The survivors have a good cerebral outcome (94% among those who were discharged alive had cerebral performance category (CPC) score 1 or 2). The organization at SU is efficient; 80% of the cardiac arrest had CPR within 1 min. Time from cardiac arrest to first defibrillation is a median of 2 min. Almost two-thirds of the patients were admitted for cardiac related diagnoses.CONCLUSION: The current study is the largest single-centre study of in hospital cardiac arrest reported according to the Utstein guidelines. We report a high survival for in-hospital cardiac arrest. We have pointed out that a functional chain of survival, short intervals before the start of CPR and defibrillation are probably contributing factors for this.

    Characteristics of patients who die in hospital with no attempt at resuscitation.2005In: Resuscitation, ISSN 0300-9572, E-ISSN 1873-1570, Vol. 65, no 3, p. 291-299Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To describe the characteristics, cause of hospitalisation and symptoms prior to death in patients dying in hospital without resuscitation being started and the extent to which these decisions were documented. MATERIALS AND METHODS: All patients who died at Sahlgrenska University Hospital in Goteborg, Sweden, in whom cardiopulmonary resuscitation (CPR) was not attempted during a period of one year. RESULTS: Among 674 patients, 71% suffered respiratory insufficiency, 43% were unconscious and 32% had congestive heart failure during the 24h before death. In the vast majority of patients, the diagnosis on admission to hospital was the same as the primary cause of death. The cause of death was life-threatening organ failure, including malignancy (44%), cerebral lesion (10%) and acute coronary syndrome (10%). The prior decision of 'do not attempt resuscitation' (DNAR) was documented in the medical notes in 82%. In the remaining 119 patients (18%), only 16 died unexpectedly. In all these 16 cases, it was regarded retrospectively as ethically justifiable not to start CPR. CONCLUSION: In patients who died at a Swedish University Hospital, we did not find a single case in which it was regarded as unethical not to start CPR. The patient group studied here had a poor prognosis due to a severe deterioration in their condition. To support this, we also found a high degree of documentation of DNAR. The low rate of CPR attempts after in-hospital cardiac arrest appears to be justified.

    Abstract [en]

    Background Time between onset of previous termcardiac arrestnext term and start of treatment is of ultimate importance for outcome. The length of time it takes to expose the previous termchestnext term in out-of-hospital previous termcardiac arrestnext term (OHCA) is not known. We aimed to compare the time from onset of OHCA until the time at which the previous termchestnext term was exposed using previous termanext term new device (S-CUT; ES Equipment, Gothenburg, Sweden) and previous termanext term pair of scissors. Methods In previous termanext term manikin study, the previous term2next term devices were compared in previous termanext term simulated previous termcardiac arrestnext term where the initial step was exposure of the previous termchest.next term The tests were performed using ambulance staff from 3 previous termdifferentnext term ambulance organizations in Western Sweden. Six previous termdifferentnext term types of clothing combinations were used. The primary choices of clothing for analyses were previous termanext term knitted sweater and shirt (indoors) and previous termanext term jacket with buttons, previous termanext term shirt, and previous termanext term college sweater (outdoors). Results The mean difference from onset of OHCA until the previous termchestnext term was exposed when S-CUT was compared with previous termanext term pair of scissors varied between 6 seconds (P = .006) and 63 seconds (P = .004; shorter with the S-CUT), depending on the type of clothing that was used. The mean differences for the clothing that was chosen for primary analyses were 23 and 63 seconds, respectively. Conclusion We found that previous termanext term new device (S-CUT) used for previous termexposing the chestnext term in OHCA was associated with previous termanext term marked shortening of procedure time as compared with previous termanext term pair of scissors.

    Tidig mobilisering av intensivvårdspatienten: Hinder och implementering2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Tidig mobilisering av patienter som vårdas på intensivvårdsavdelning (IVA) har visat sig minska risken för komplikationer under och efter vårdtiden samt förkorta tiden i respirator. Trots påvisad god effekt har det visat sig vara svårt att få genomslag för denna behandlingsåtgärd. Syftet med denna litteraturstudie var att studera vilka hinder/barriärer som finns mot införandet av tidig mobilisering och vad som gjorts för att implementera denna förändring av IVA-vården på andra kliniker. Studien är en litteraturstudie baserad på artiklar utvalda enligt förutbestämda kriterier ur databaserna Cinahl och Medline.

    Resultaten summerades i två huvudteman ”Hinder för tidig mobilisering” respektive ”Implementering av tidig mobilisering”. Resultaten visade att hinder för tidig mobiliseringen ofta berodde på en kombination av följande faktorer: okunskap, kulturen på avdelningen, bristande samarbete, resursbrist och patientrelaterade faktorer. Okunskap gäller både brist på kunskap om varför tidig mobilisering är bra, men även om hur och när mobilisering kan genomföras. Om det inte fanns någon kultur för tvärprofessionellt samarbete så upplevdes detta som ett stort hinder på vägen. Implementering av tidig mobilisering gick mycket ut på att överbrygga de barriärer som definierats. Utbildning för att möta bristen på kunskap, organisatoriska förändringar såsom prioriterade samarbete mellan olika yrkesgrupper och tydliggörande av var och ens roll i processen samt ett väl genomarbetat protokoll för hur tidig mobilisering skulle genomföras, utgjorde grundstenarna för en lyckad implementering. För att öka tillämpningen av tidig mobilisering inom svensk intensivvård föreslår författarna en strukturerad plan enligt ovan.

    Användningen av 5S och TPM på en företagskritisk maskinstation inom produktionen2017Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    The project was performed at Parker Hannifin Cylinder Division at Falköping, where a station in the most critical flow at the production has been studied, which is the hand welding station. Within this report, the purpose is to identify disturbances, in order to eliminate and reduce these by coming up with improvement proposals. Furthermore, the aim is to help improve the company's work with 5S and TPM (Total Productive Maintenance). A combination of tools and concepts are being used in this project when generating improvement proposals to avoid the risk of falling back into old habits and facilitate the work. The combination of concepts, intends to be continued to work with, in order to facilitate for the company to reach even higher results.The methodology of TPM is the basis of the project, although it is not about a complete implementation of TPM, but is limited to chosen parts since it is a time consuming process that can go on for years. The main focus of TPM is about the first pillar, 5S. Action plans for how to solve these problems and how to achieve the desired state has been established.Thereafter, the researchers in cooperation with the company´s staff have implemented a couple of small improvement proposals. Further improvement proposals have also been presented in this report, but due to the limited time no implementations was made.Moreover, this project is divided into a couple of phases. Situational analysis has been made through both interviews with staff and observation studies. Analysis has also been made by some numeric data taken out by researchers and partly through mapping the equipment. The intention of this is to create a status image of the current situation over the hand welding station. The current state has shown the appearance of problems and challenges that exist. Additional wastages and disturbances in the station can come up to the surface and can thus easily be identified. In turn, occurring wastages and disturbances can be eliminated and the amount of wasted time reduced with help of the action plans to reach a future state.Another method that occurs is spaghetti charts. It has been used for mapping up the existing procedures during the process of the orders in the station, and by that identified different types of disturbances. In addition, the creation of a Value Stream Mapping (VSM) has been made. The map is used as a measurement to identify how much time on a working day that is spent as value adding time and non-value adding time of work.

    Ta vara på äpplen som restprodukt2018Independent thesis Basic level (degree of Bachelor of Fine Arts), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In Sweden, about 1.2 million tons of food waste is thrown away per year. Much of the waste is fruit and vegetables because of the consumers misconceptions about how a fruit and vegetable should appear in order to be edible. Food waste is bad both for the economy and the environment. Therefore, a changed attitude from the consumers is needed to reduce the waste of food. Lyckans äpple is a cider factory that generates about 2.5 tons of apple waste per year. At present there is no process for handling these. Therefore, the purpose of this thesis is to find out if it is possible to make use of the apple waste. To investigate if it is possible to get an alcoholic drink and some type of dried food product. Also to find out how much growth that can be obtained out of Neurospora intermedia and Aspergillus oryzae. A variety of different methods have been used. Fermentation to get an alcoholic drink, 70°C oven to get a dried food product and Solid State Fermentation to get the growth of the fungus Neurospora intermedia and Aspergillus oryzae. The result shows that an alcoholic beverage can be extracted from apple waste. To get a good and tasty beverage from apple waste with only water and fungus added is difficult because there are a lot of flavors from the apples that disappear when the must is done. On the other hand, a good beverage could be obtained using additives because the beverage has a good taste-potential. The drying gave good results. All results had basically the same taste but different texture. Getting a food product is possible. Being able to dry apple wastes are a good option as the process is easy, it tastes good and the apple waste contains good substances for the body. Results from Solid State Fermentation varied. In some experiments, the growth was greater and in others less.

    Den ensidiga mångkulturen: bibliotekariers syn på litteratur i svensk översättning2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This Bachelor's thesis seeks to illuminate the onesided cultural leanings in literary translations in libraries. Through semi-structured interviews it seeks to explore the view of librarians on the possibilities and obstructions in providing library users with literature of a wide cultural spectrum. In particular, this paper focuses on the dominance of Anglo-Saxon literature in comparison to literature from other geographical and cultural areas. The paper relies on the field, symbolic capital, consecration and habitus theories created by French sociologist Pierre Bourdieu in its attempt to bring light on the workings of translations, marketing and user-requests and their influence on library collections. By comparing the answers from the interviews with these theories it finds that libraries generally try to adapt their collection and modify their purchases of new media to fit their user's requests and needs. It also finds that the users themselves are generally influenced by the media. In other words, while the libraries may try to keep a broad cultural and lingual collection of literature the users do not request non-Anglo-Saxon literature in particular. Therefore it draws the conclusion that more studies are needed on the workings of user requests and on the range of literary translations provided by publishers as well as their exposure in the media.

    Trace of Flicker Sources by using the Quantity of Flicker power.2008In: IEEE Transactions on Power Delivery, ISSN 0885-8977, E-ISSN 1937-4208, Vol. 23, no 1, p. 465-471Article in journal (Refereed)
    Abstract [en]

    Industries that produce flicker are often placed close to each other and connected to the same power grid system. This implies that the measured flicker level at the point of common coupling (PCC) is a result of contribution from a number of different flicker sources. In a mitigation process it is essential to know which one of the flicker sources is the dominant one. We propose a method to determine the flicker propagations and trace the flicker sources by using flicker power measurements. Flicker power is considered as a quantity containing both sign and magnitude. The sign determines if a flicker source is placed downstream or upstream with respect to a given monitoring point and the magnitude is used to determine the propagation of flicker power throughout the power network and to trace the dominant flicker source. This paper covers the theoretical background of flicker power and describes a novel method for calculation of flicker power that can be implemented in a power network analyzer. Also conducted simulations and a field test based on the proposed method will be described in the paper.

    On Tracing Flicker Sources and Classification of Voltage Disturbances2007Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Developments in measurement technology, communication and data storage have resulted in measurement systems that produce large amount of data. Together with the long existing need for characterizing the performance of the power system this has resulted in demand for automatic and efficient information-extraction methods. The objective of the research work presented in this thesis was therefore to develop new robust methods that extract additional information from voltage and current measurements in power systems. This work has contributed to two specific areas of interest. The first part of the work has been the development of a measurement method that gives information how voltage flicker propagates (with respect to a monitoring point) and how to trace a flicker source. As part of this work the quantity of flicker power has been defined and integrated in a perceptionally relevant measurement method. The method has been validated by theoretical analysis, by simulations, and by two field tests (at low-voltage and at 130-kV level) with results that matched the theory. The conclusion of this part of the work is that flicker power can be used for efficient tracing of a flicker source and to determine how flicker propagates. The second part of the work has been the development of a voltage disturbance classification system based on the statistical learning theory-based Support Vector Machine method. The classification system shows always high classification accuracy when training data and test data originate from the same source. High classification accuracy is also obtained when training data originate from one power network and test data from another. The classification system shows, however, lower performance when training data is synthetic and test data originate from real power networks. It was concluded that it is possible to develop a classification system based on the Support Vector Machine method with “global settings” that can be used at any location without the need to retrain. The conclusion is that the proposed classification system works well and shows sufficiently high classification accuracy when trained on data that originate from real disturbances. However, more research activities are needed in order to generate synthetic data that have statistical characteristics close enough to real disturbances to replace actual recordings as training data.

    Measuring method for deciding direction to a flickering source.2013Patent (Other (popular science, discussion, etc.))
    Abstract [en]

    The present invention relates to a method for deciding the direction to a flickering source in relation to a measurement point in an electrical network with alternating current with a network frequency (fc) with low-frequency amplitude variation from the flickering source. The invention is characterized in that the method comprises the steps: - recording of an amplitude-modulated current signal (i(n)) comprising signals that originate from the network frequency (fc) and the low-frequency amplitude variations in the current signal (i(n)); - recording of an amplitude-modulated voltage signal ((u(n)) comprising signals that originate from the network frequency (fc) and the low-frequency amplitude variations in the voltage signal (u(n)); - creation of a flicker power with a sign value by multiplication of the low-frequency amplitude variations in the current signal and the low-frequency amplitude variations in the voltage signal, and - analysis of the sign value, with the sign value indicating in which direction the flickering source is to be found in relation to the measurement point. The method also comprises an arrangement designed to be used when carrying out the method.

    Performance Tests of a Support Vector Machine used for Classification of Voltage Disturbances2006Conference paper (Refereed)
    Abstract [en]

    This paper proposes a novel method for classifying voltage disturbances in electric power systems by using the Support Vector Machine (SVM) method. The proposed SVM classifier is designed to classify five common types of voltage disturbances and experiments have been conducted on recorded disturbances with good classification results. The proposed SVM classifier is also shown to be robust in terms of using training data and testing data that originate from two different power networks.

    Abstract [en]

    The support vector machine (SVM) is a powerful method for statistical classification of data used in a number of different applications. However, the usefulness of the method in a commercial available system is very much dependent on whether the SVM classifier can be pretrained from a factory since it is not realistic that the SVM classifier must be trained by the customers themselves before it can be used. This paper proposes a novel SVM classification system for voltage disturbances. The performance of the proposed SVM classifier is investigated when the voltage disturbance data used for training and testing originated from different sources. The data used in the experiments were obtained from both real disturbances recorded in two different power networks and from synthetic data. The experimental results shown high accuracy in classification with training data from one power network and unseen testing data from another. High accuracy was also achieved when the SVM classifier was trained on data from a real power network and test data originated from synthetic data. A lower accuracy resulted when the SVM classifier was trained on synthetic data and test data originated from the power network.

    Textilt avfall och textil återvinning  i Borås Stad2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The consumption of textiles is increasing more and more, meanwhile there are vigorous efforts both from the textile industry and controlling companies to promote sustainable consumption. A significant amount of textiles discarded in household waste, which is an untapped resource that should be taken advantage of. Two methods to use textile waste is to reuse and recycling it. The reuses of textile materials are today well developed in Sweden, however, there are currently no existing system for recycling textiles.

    The purpose of this study is to investigate Borås Stad’s textile waste and the textile recycling. The reason I chose Borås is because the city has an old history in the Swedish textile industry and today strives to be in top of the textile innovations. The methods being used in this study are a literature studies and a interview.

    Borås Stad actively works to encourage the citizens to reuse and recycle their textile waste. The opportunity to recycle textiles is today only in the special collecting boxes. Borås Stad has nowadays, because of size- and economical aspects, not an own developed recycle system for textile waste.

    Abstract [en]

    This report describes the process of developing a website prototype with a focus on User Experience and Information Architecture. The study has been undertaken on behalf of a relatively small interiordesign company, whose business will eventually be transferred from selling products and services in both their physical store and on their website, to selling only on the web. The focus of the study was to investigate the target audience's information and experience needs when visiting the website, which was taken into account in the process of developing a user-centered website prototype. While the maingoal was to create a user-centered website prototype that aimed to promote positive user experiences, another objective was to develop a website that can also maintain the company's corporate identity. The future users of the website were involved during the design process. A semi-structured interview was conducted followed by two user tests, one on the the existing website and one on the produced prototype. Participants were asked to perform tasks while they gave commentary about their reactions and perceptions. The results from the user test show that there is a significant connection between the audience’s experience and their information needs. This in turn also relates to how the target groupexperiences the corporate identity. The results confirm that structure, content and a esthetics aret hree aspects that are inherently linked and important to consider.

    "Nothing can be changed if the people don’t change": Costa Rican registered nurses’ views and experiences of caring for patients with dengue fever2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Dengue fever has increased to the point where it has become a major international public health and economical problem, mainly in urban and semi-urban areas in tropical and subtropical regions. Worldwide 2,5 billion people live in regions where dengue can be transmitted and approximately 100 million people get infected yearly. In 2002 there was a great outbreak in Latin America, and Costa Rica was in the top three regarding reported cases. At the time of writing, reports show that cases of dengue are currently low in Costa Rica. Although the figures vary, dengue remains a public health problem.

    This study aimed to describe Costa Rican registered nurses’ views and experiences of caring for patients with dengue fever. Data were collected with semi-structured interviews and conducted with eight registered nurses from Costa Rica, and analysed with qualitative content analysis method with search for similarities and differences which later were categorized. The result was divided into five categories; the conception about dengue fever, caring, patient education, prevention and the future. The result showed a similar perception of the disease and was described as terrible, causing a lot of suffering for the patient, as well as a burden on the health care, that requires large financial resources. To control dengue and suppress the proliferation it is important to have different preventive means and to educate people to achieve a change of the mindset.

    Abstract [en]

    This article describes a study that investigated the need for and challenges connected to the establishment of a collaboratory - a sociotechnical forum where information and other resources can be made accessible and used by practitioners within library and information science. In order to identify needs and challenges interviews were carried out with a number of practitioners at a number of different institutions. The results reveal that there is a need for a collaboratory in order to facilitate the sharing of personal knowledge “on demand”. It is of great importance that the collaboratory is well integrated with practitioner’s daily activities.

    Needs and challenges with respect to establishing a collaboratory within library and information science: Practioners' perspectives2006In: Proceedings of the Information Use in Information Society Conference, 2006Conference paper (Refereed)
    Abstract [en]

    This paper reports on a study that explored the needs and challenges with respect to the creation of a collaboratory for library and information science practitioners. To identify needs and challenges interviews were conducted with practitioners at a variety of institutions. The results suggest that there is a need for a collaboratory to facilitate on-demand, personalized knowledge sharing. The collaboratory should also be well integrated into the everyday practice of library and information science practitioners.

    Clinical consequences of the introduction of mechanical chest compression in the EMS system for treatment of out-of-hospital cardiac arrest-a pilot study.2006In: Resuscitation, ISSN 0300-9572, E-ISSN 1873-1570, Vol. 71, no 1, p. 47-55Article in journal (Refereed)
    Abstract [en]

    AIM: To evaluate the outcome among patients suffering from out-of-hospital cardiac arrest (OHCA) after the introduction of mechanical chest compression (MCC) compared with standard cardiopulmonary resuscitation (SCPR) in two emergency medical service (EMS) systems. METHODS: The inclusion criterion was witnessed OHCA. The exclusion criteria were age < 18 years, the following judged etiologies behind OHCA: trauma, pregnancy, hypothermia, intoxication, hanging and drowning or return of spontaneous circulation (ROSC) prior to the arrival of the advanced life support (ALS) unit. Two MCC devices were allocated during six-month periods between four ALS units for a period of two years (cluster randomisation). RESULTS: In all, 328 patients fulfilled the criteria for participation and 159 were allocated to the MCC tier (the device was used in 66% of cases) and 169 to the SCPR tier. In the MCC tier, 51% had ROSC (primary end-point) versus 51% in the SCPR tier. The corresponding values for hospital admission alive (secondary end-point) were 38% and 37% (NS). In the subset of patients in whom the device was used, the percentage who had ROSC was 49% versus 50% in a control group matched for age, initial rhythm, aetiology, bystander-/crew-witnessed status and delay to CPR. The percentage of patients discharged alive from hospital after OHCA was 8% versus 10% (NS) for all patients and 2% versus 4%, respectively (NS) for the patients in the subset (where the device was used and the matched control population). CONCLUSION: In this pilot study, the results did not support the hypothesis that the introduction of mechanical chest compression in OHCA improves outcome. However, there is room for further improvement in the use of the device. The hypothesis that this will improve outcome needs to be tested in further prospective trials

    Characteristics and outcome among patients suffering from out-of-hospital cardiac arrest with the emphasis on availability for intervention trials.2007In: Resuscitation, ISSN 0300-9572, E-ISSN 1873-1570, Vol. 75, no 3, p. 460-468Article in journal (Refereed)
    Abstract [en]

    AIM: To describe all patients treated for out-of-hospital cardiac arrest (OHCA) according to the Utstein criteria and their characteristics and outcome with emphasis on whether they were available for early intervention trials. DESIGN: Retrospective analysis of a study where data were collected prospectively. SETTING: The Municipality of Göteborg/Mölndal in Sweden. PATIENTS: All patients suffering from out-of-hospital cardiac arrest in the Municipality of Göteborg/Mölndal in whom cardiopulmonary resuscitation (CPR) was attempted between May 2003 and May 2005. INTERVENTIONS: Part of the study cohort, i.e. patients with a witnessed, non-traumatic, out-of-hospital cardiac arrest were distributed (cluster) to mechanical (LUCAS) or manual chest compression. RESULTS: The overall survival to discharge from hospital among the 508 patients was 8.5%. The corresponding value for non-cardiac cases was 5.1% and for cardiac cases if crew witnessed 16.1%, bystander witnessed 12.7% and non-witnessed 1.4%. Fifty-nine percent of the patients fulfilled the inclusion criteria for the trial and had no exclusion criteria and 9.7% of these survived to discharge. Ten percent of patients fulfilled the inclusion criteria but were excluded and 20.4% survived to discharge. Thirty-one percent of patients did not fulfil the inclusion criteria and 2.5% survived. Among patients included in the LUCAS group, many of the survivors, 10/13 (77%), experienced a rapid return of spontaneous circulation (ROSC) before the application of the device. CONCLUSION: Among patients with OHCA in whom CPR was started 8.5% survived to hospital discharge and 59% were theoretically available for an early intervention trial. These patients have a different outcome compared with patients not available. However, among those available, the majority of survivors had a rapid ROSC before the application of the intervention (LUCAS). This raises concerns about the potential for early intervention trials to improve outcome after OHCA.

    Dispatch codes of out-of-hospital cardiac arrest should be diagnosis related rather than symptom related2010In: European journal of emergency medicine, ISSN 0969-9546, E-ISSN 1473-5695, Vol. 17, no 5, p. 265-269Article in journal (Refereed)
    Abstract [en]

    Objective: To describe the characteristics and outcome in out-of-hospital cardiac arrest (OHCA) in relation to (i) whether OHCA was coded by the dispatcher as a diagnosis or as a symptom and (ii) the delay until the first unit was alerted at the dispatch centre. Methods: OHCA patients in Göteborg, during 17 months, excluding OHCA after calling the rescue team. Results: Among 250 cases, 20% were coded as a diagnosis (i.e. CA) with or without ongoing cardiopulmonary resuscitation (CPR). Dispatch codes for the remaining 200 patients (80%) were mostly symptom related (unconsciousness in 61%, codes related to breathing problems in 10%, other codes in 24% and missing in 5%). Patients in whom the dispatchers coded the call as CA had an earlier start to CPR after collapse (median 2 vs. 10 min; P<0.0001) and a higher rate of bystander CPR (86% vs. 42%; P<0.0001). Furthermore, they tended to have a higher rate of survival to hospital discharge (14.0% vs. 6.5%; P  = 0.09). The median delay until the first unit was alerted was 1.8 min. Survival to hospital discharge was 10.0% if the delay was below median and 6.7% if the delay was above median (P = 0.48). Conclusion: Patients with OHCA who were not coded by dispatchers as such had a long delay to the start of CPR and a low survival. Dispatching according to diagnosis, that is, CA seems to improve these parameters most likely reflecting a more optimal communication between the dispatcher and the caller as well as the rescue team.

    Implementation of mechanical chest compression in out-of-hospital carfdiac arrest in an emergency medical service system2013In: American Journal of Emergency Medicine, ISSN 0735-6757, E-ISSN 1532-8171, Vol. 31, no 8, p. 1196-1200Article in journal (Refereed)
    Abstract [en]

    AIM: The aim of this study is to describe the outcome changes after out-of-hospital cardiac arrest (OHCA) in Gothenburg, Sweden, after introduction of mechanical chest compression (MCC). METHODS: Following introduction of MCC, 1183 OHCA patients were treated from November 1, 2007, to December 31, 2011 (period 2). They were compared with 1218 OHCA patients before MCC was introduced from January 1, 1998, to May 30, 2003 (period 1). Patients in period 2 were evaluated for survival in relation to MCC use. RESULTS: The percentage of patients admitted to hospital alive increased from 25.4% to 31.9% (P < .0001). Survival to 1 month increased from 7.1% to 10.7% (P = .002) from period 1 to period 2. The proportion of ventricular fibrillation/ventricular tachycardia decreased in period 2 (P = .002). However, bystander cardiopulmonary resuscitation (P < .0001), crew-witnessed cases (P = .04), percutaneous coronary intervention (P < .0001), therapeutic hypothermia (P < .0001), and implantable cardioverter-defibrillator use (P = .01) increased, as did time from call to emergency medicine service arrival (P < .0001) and to defibrillation (P = .006). In period 2, 60% of OHCA patients were treated with MCC. The percentages admitted alive to hospital (MCC vs no MCC) were 28.6% and 36.1% (P = .008). Corresponding figures for survival to 1 month were 5.6% and 17.6% (P < .0001). In the MCC group, we found increase in the delay from collapse to defibrillation (P < .0001), greater use of adrenaline (P < .0001), and fewer crew-witnessed cases (P < .0001). CONCLUSION: Survival to 1 month after implementation of MCC was higher than before introduction. However, patients receiving MCC had low survival. Although case selection might play a role, results do not support a widespread use of MCC after OHCA.

    Passive leg raising during cardiopulmonary resuscitation in out-of-hospital cardiac arrest: Does it improve circulation and outcome?2010In: Resuscitation, ISSN 0300-9572, E-ISSN 1873-1570, Vol. 81, no 12, p. 1615-1620Article in journal (Refereed)
    Abstract [en]

    Background Passive leg raising (PLR), to augment the artificial circulation, was deleted from cardiopulmonary resuscitation (CPR) guidelines in 1992. Increases in end-tidal carbon dioxide (PETCO2) during CPR have been associated with increased pulmonary blood flow reflecting cardiac output. Measurements of PETCO2 after PLR might therefore increase our understanding of its potential value in CPR. We also observed the alteration in PETCO2 in relation to the return of spontaneous circulation (ROSC) and no ROSC. Methods and results The PETCO2 was measured, subsequent to intubation, in 126 patients suffering an out-of-hospital cardiac arrest (OHCA), during 15min or until ROSC. Forty-four patients were selected by the study protocol to PLR 35cm; 21 patients received manual chest compressions and 23 mechanical compressions. The PLR was initiated during uninterrupted CPR, 5min from the start of PETCO2 measurements. During PLR, an increase in PETCO2 was found in all 44 patients within 15s (p=0.003), 45s (p=0.002) and 75s (p=0.0001). Survival to hospital discharge was 7% among patients with PLR and 1% among those without PLR (p=0.12). Among patients experiencing ROSC (60 of 126), we found a marked increase in PETCO2 1min before the detection of a palpable pulse. Conclusion Since PLR during CPR appears to increase PETCO2 after OHCA, larger studies are needed to evaluate its potential effects on survival. Further, the measurement of PETCO2 could help to minimise the hands-off periods and pulse checks.
