Background Cardiopulmonary resuscitation (CPR) increases significantly the chance of survival in cases of a cardiac arrest. The ability to respond quickly and effectively to a cardiac arrest rests on nurses being competent, prepared and up-to-date. Nursing student’s knowledge in CPR and perceptions of their own training are crucial for the pursuit of the education of professional nurses.    Aim Investigate the prerequisites for a good care of patients in need of CPR by assessing  Vietnamese nursing students' knowledge in CPR as well as their perceptions on their education in CPR.      Method A quantitative, cross sectional-study was conducted. A modified version of a questionnaire developed by the Swedish council of CPR was used. Nursing students at University of Medicine and Pharmacy in Ho Chi Minh City were asked to participate. The gathered data were analyzed with descriptive statistics, t-test and chi2 -test.   Result The participants answered right on 41 % of the questions (571/1404). The mean-score was 5.25 and the score ranged from 0 to 9 out of 13 points on the questionnaire. Participants answered correctly on most questions regarding basic CPR and were foremost wrong about questions regarding defibrillation. There was no association between a high result on the questionnaire and students rating a high grading on preparedness and/or satisfaction. No significant difference could be found based on gender.   Conclusion The knowledge in CPR, based on this survey, is generally low. One plausible explanation could be that the questionnaire did not fit the education of the participants. / Bakgrund Hjärt- och lungräddning (HLR) ökar avsevärt chanserna att överleva vid ett hjärtstopp. Att kunna reagera snabbt och effektivt på hjärtstillestånd kräver att sjuksköterskor är kompetenta och förberedda. Sjuksköterskestudenters kunskaper i HLR och deras uppfattningar om sin utbildning är avgörande för den fortsatta utbildningen av professionella sjuksköterskor.   Syfte Undersöka förutsättningarna för en patientsäker vård inom HLR, genom att kartlägga vietnamesiska sjuksköterskestudenters kunskaper i HLR samt att undersöka deras uppfattning om sin utbildning i HLR.   Metod En kvantitativ, tvärsnittsstudie genomfördes. En modifierad version av ett frågeformulär utvecklat av Svenska rådet för hjärt- och lungräddning (HLR-rådet) användes. Sjuksköterskestudenter i en klass från University of Medicine and Pharmacy, i Ho Chi Minh City blev ombedda att delta. Den insamlade informationen analyserades med beskrivande statistik, t-test och chi2-test.   Resultat Deltagarna svarade rätt på 41% av frågorna (571/1404). Det totala medelvärdet var 5.25 och poängen skilde sig från 0 till 9 av 13 poäng på frågeformuläret. Deltagarna svarade korrekt på de flesta frågor angående grundläggande HLR och svarade främst fel på frågor angående defibrillering. Det fanns inget samband mellan ett högt resultat på frågeformuläret och elever som ansåg sig vara förberedda och/eller nöjda med sin utbildning. Ingen signifikant skillnad i resultat kunde hittas baserat på kön. Slutsats Kunskaperna i HLR, baserat på den genomförda studien, är generellt låga. När det kommer till vissa frågor kan en orsak vara att frågeformuläret inte var anpassat efter deltagarnas utbildning.

A parada cardiorrespiratória (PCR) é a principal causa de morte em países desenvolvidos e em desenvolvimentos, ocorrendo principalmente em ambientes extra hospitalares. Frente a esse panorama mundial considerado um problema de saúde pública atual, a capacitação de leigos no Suporte Básico de Vida (SBV) com uso da simulação clínica tem papel relevante para a melhoria das taxas de sobrevivência das vítimas de PCR. Estudo com objetivo de avaliar o conhecimento (teórico) e das habilidades (práticas) de leigos antes e após a sua participação no curso de SBV para leigos submetidos a estratégias de ensino-aprendizagem, aula expositivo-dialogada e atividade prática em laboratório de habilidades ou aula simulada no atendimento a PCR/RCP com SBV para leigos. Estudo com delineamento quase experimental, abordagem quantitativa com delineamento tempo-série. A população consistiu dos estudantes do primeiro ao quarto semestre de graduação da Faculdade de Enfermagem da Universidade Federal do Mato Grosso e a amostra de 104 estudantes que participaram do curso em SBV para leigos em duas etapas. Na etapa I todos os estudantes foram submetidos ao pré teste teórico, à aula expositivo-dialogada seguida de atividade prática em laboratório de habilidades com manequim de média fidelidade e uso do Desfibrilador Externo Automático (DEA), simulação clínica em laboratório utilizando o mesmo manequim e DEA e pós teste teórico imediato. A Etapa II ocorreu de 15 a 20 dias após a primeira e todos os estudantes foram submetidos à simulação clínica em laboratório utilizando o mesmo manequim de média fidelidade e DEA seguido de pós teste teórico mediato. Elaboraram-se os instrumentos de avaliação teórica, cenário de simulação e OSCE - avaliação clínica objetiva e estruturada no cenário de simulação com (checklist), validados em aparência e conteúdo por comitê de juízes. A estratégia de coleta de dados foi o curso de SBV para leigos. Foram avaliados as avaliações teóricas e OSCE (Exame Clínico Objetivo Estruturado) - avaliação clínica estruturada em Laboratório de Simulação, este último empregando como ferramenta o manequim de média-fidelidade e DEA. A atividade foi filmada e analisada por três avaliadores. Analisaram-se os desfechos nas etapas I e II do curso de SBV para leigos: desempenho teórico nos testes teóricos e práticos no OSCE, tempo de execução total e de cada domínio do OSCE e a qualidade das compressões torácicas externas (CTE) quanto a frequencia e profundidade em 120 segundos de reanimação cardiopulmonar (RCP). Resultados: 86 estudantes eram do sexo feminino e 18 do sexo masculino, a idade média 23,32±6,66 anos. No pré-teste a nota média foi de 3,52±2,03, e a mediana 3,0. No pós-teste imediato (pós 1) a nota média foi 8,01±1,19 (mediana 8,0) e no pós teste mediato (pós 2) foi de 7,41±2,68 (mediana 8,5). Comparando-se as médias obtidas no pré-teste, pós 1 e pós 2 há diferença estatisticamente significante (p<0,001) com retenção do conhecimento. Comparando as notas do pós 1 e pós 2 teóricos evidenciou diferença estatisticamente significante (p=0,019) com perda do conhecimento no pós 2. A média no OSCE na etapa I (pós 1) foi 3,63±0,30 e na etapa II (pós 2) de 3,63±0,31; comparou-se tais notas verificando-se que não há diferença estatisticamente significante (p=0,966). O tempo médio de execução do OSCE no pós 1 foi de 156,96±8,16s e no pós 2 foi de 138,68±43,58s, havendo diferença estatisticamente significante (p<0,001). O domínio de intervenção do OSCE \"Chegada em Cena\" apresentou média 20,78±6,20s no pós 1 e 16,46±4,56s no pós 2, o domínio \"Checar a responsividade\" média de 6,38±3,48s no pós 1 e 5,13±2,36s no pós 2, o domínio \"Usar o DEA\" média de 77,30±14,45s no pós 1 e 66,80±11,44s no pós 2, todos com diferença estatisticamente significante (p<0,001). Avaliando a qualidade das CTE a profundidade média atingida em milímetros (mm) apresentou média de 36,26±9,62 (mediana 35,00) no pós 1 e 39,36±10,96 (mediana 40,00) no pós 2. O nº de CTE média por minuto apresentou média de 116,01±21,72 (mediana 116,00) no pós 1 e 98,94±19,52 (mediana 100,00) no pós 2, o nº total de compressões (CTE) em 120 segundos apresentou média de 227,88±41,81 (mediana 226,00) no pós 1 e 197,31±30,42 (mediana 195,50) no pós 2, o nº de CTE muito superficiais média de 132,20±89,94 (mediana 146,50) no pós 1 e 74,96±75,76 (mediana 53,00) no pós 2, todos com diferenças estatisticamente significante (p<0,001). Já o nº de CTE incompletas apresentou média de 25,09±56,95 (mediana 0,00) no pós 1 e 14,51±35,45 (mediana 0,00) no pós 2 com diferença estatisticamente significante (p=0,012). No presente estudo, apesar de diferentes estratégias de ensino abordarem o SBV para leigos, os resultados demonstram que as mesmas foram eficazes e os objetivos de aprendizagem foram alcançados, pois houve incremento nas notas obtidas nos pós-testes e no OSCE tanto na etapa I quanto na etapa II em relação ao conhecimento prévio e habilidades, porém houve perda da retenção de conhecimento e habilidade de 15 a 20 dias após o curso de SBV para leigos o que reforça a necessidade da capacitação permanente / Cardiac arrest is the leading cause of death in developed and developing countries, and mainly occurs in non-hospital environments. With this global scenario, which is considered a present public health problem, training laypeople in Basic Life Support (BLS) with clinical simulation has an important role in improving survival rate of the cardiac arrest victims. This present study aims to evaluate the knowledge (theoretical) and skills (practical) of laypeople before and after the BLS training underwent to teaching and learning strategies, expository and dialogue class and practical activities in skills lab or simulation class in CPR/CPA. This study has an almost experimental, quantitative and time-series approach. The population study is composed of students from the first to fourth semester of Nursing at Federal University of Mato Grosso (UFMT) and the sample of 104 participants in BLS for laypeople in two steps. In Step 1, all the students had to undergo to the theoretical pretest, expository and dialogue class followed by practical activity in the skills lab with a mid-fidelity manikin and using automated external defibrillator (AED), clinical simulation in the lab using the same manikin and AED and immediate theoretical posttest. Step 2 occurred from the 15th to 20th days after the first one and all the students had to undergo to clinical simulation in the lab using the same mid-fidelity manikin and AED followed by immediate theoretical posttest. It was elaborated theoretical evaluation tools, simulation scenario and OSCE - objective structured clinical examination in the clinical scenario with checklist, validated in aspect and content by a judges committee. The data collection strategy was the BLS for laypeople. It was evaluated the theoretical tests and OSCE (objective structured clinical examination) - clinical examination structured in Simulation Lab, using as tool the mid-fidelity manikin and AED. The activity was filmed and analysed by three evaluators. The outcomes of Step 1 and 2 of BLS for laypeople were analysed: theoretical performance on theoretical and practical tests in OSCE, total execution time, each OSCE realm and the quality of external chest compression (ECC) such as frequency and deepness in 120 seconds of cardiopulmonary resuscitation (CPR). Outcomes: 86 female and 18 male students, median age 23.32±6.66. Median score in pretest was 3.52±2.03 and the average 3.0. At immediate posttest (post 1) the median was 8.01±1.19 (average = 8.0) and at immediate posttest (post 2) 7.41±2.68 (average = 8.5). Comparing the pretest averages and posttests 1 and 2, there is a statistically significant difference (p<0.001) of knowledge retention. Comparing theoretical posttests 1 and 2 revealed the statistically significant difference (p=0.019) with knowledge loss at posttest 2. Step 1 OSCE average (posttest 1) was 3.63±0.30 and Step 2 (posttest 2) 3.63±0.31; when compared, these scores demonstrated that there is not a statistically significant difference (p=0.966). The OSCE execution time average at posttest 1 was 156,96±8,16 seconds and at posttest 2 138.68±43.58 seconds, which demonstrated statistically significant difference (p<0.001). OSCE intervention realm \"Arrival on the scene\" showed posttest 1 20,78±6,20s and posttest 2 16,46±4,56s averages, the realm \"Check Responsiveness\" had averages of 6,38±3,48s in posttest 1 and 5,13±2,36s in posttest 2, the realm \"Using DEA\" averages of 77,30±14,45s in posttest 1 and posttest 2 of 66,80±11,44s, all of them with statistically significant difference (p<0,001). Evaluating the quality of ECT the reached deepness average in millimeters (mm) resulted 36.26±9.62 (average 35.00) in posttest 1 and 39.36±10.96 (average 40.00) in posttest 2. The number of ECC per minute showed 116.01±21.72 (average 116.00) in posttest 1 and 98.94±19.52 (average 100.00) in posttest 2, the total of compressions (ECC) in 120 seconds showed 227.88±41.81 (average 226.00) and 197.31±30.42 (average 195,50) in posttest 2, the number of surface ECC 132.20±89.94 (average 146.50) and 74.96±75.76 (average 53,00) in posttest 2, all of them with statistically significant difference (p<0,001). In the incomplete ECC showed 25.09±56.95 (average 0,00) in posttest 1 and 14.51±35.45 (average 0,00) in posttest 2 with statistically significant difference (p=0,012). In this present study, besides the different teaching strategies approaches for laypeople, the outcomes demonstrate that they were effective and the learning goals reached, since the posttests had higher scores in previous knowledge and skills of steps 1 and 2 of OSCE. However it showed a loss of knowledge and skills retention in 15 to 20 days after the BLS training for laypeople, what demonstrates the need of permanent training

Thesis (MPH) --University of Limpopo, 2007. / Aim of the study: To determine knowledge of CPR and heart attack or cardiac arrest signs and symptoms among university students. Study Design: A questionnaire based descriptive, cross – sectional study. Setting: University of Limpopo – Turfloop Campus in Limpopo Province of South Africa. Subjects: A total sample of 400 students participated in the study. The sample was selected randomly using simple random sampling techniques. Outcome measures: The faculty, age, gender and level of study were determined as well as the knowledge each student has on signs and symptoms of impending heart attack and CPR.Results: Of the 400 students only 26% (n=104) knew the signs and symptoms of an impending heart attack as well as out of hospital management of heart attack by performing CPR. There were differences between and within faculties, age groups, gender and level of study. Based on the Bonferroni test the student from faculty of Sciences, Health and Agriculture are more likely (p-value 0017) to know when to perform CPR compared to students from other faculties. Level of study is not associated (p-value 0128) with how much the students know about the timing and indications of CPR. Overall female students performed worse with 79% (n=123) responding incorrectly to the questions compared to 69% (n=169) males. Conclusion: Based on the results of this study it safely can be concluded that the students’ knowledge of signs and symptoms of an impending heart attack and CPR procedure is poor. It is therefore important for the university as a center of teaching and learning to consider including as part of university curriculum, basic life support and first aid courses which include CPR. The inclusion of basic life support and first aid in university curriculum will prepare students to be able to effectively manage out of hospital heart attack and reduce mortality resulting from the latter. The findings of this study might to a certain extent be reflecting what the public’s knowledge on the subject is, hence the need for the policy makers to take serious note of the findings when public health promotion programmes are developed.

<p>Death from heart diseases is the most common type of mortality in western countries and the survival rate of cardiac arrest is dismally low.

The Analysis of Ilan¡¦s Out-of-Hospital Cardiac Arrest (OHCA) Patients Abstract The study uses Ilan¡¦s out-of-hospital cardiac arrest (OHCA) patients as the research object to understand the variable backgrounds of OHCA patients how they are affected by first aid factors between the period of pre-hospital and post-hospital admission. The study also discusses whether there is a correlation between first aid factors and first aid prognosis among those OHCA patients during pre-hospital and post-hospital admission periods. The study is retrospective and based on the Utstein style format. It collects 284 out-of-hospital cardiac arrest (OHCA) patient cases with trauma and non-trauma (282 effective samples) in an example of a regional teaching hospital in Ilan from 2007 to 2009. It uses descriptive statistics, independent sample t test, and Chi-Square test as the statistical analysis to obtain the following conclusions: 1. There are 282 effective sample patients in the study. There are 57 patients ( 20.2 %) who were return of spontaneous circulation (ROSC) after cardiac arrest approximately 14.77 minutes on average. There are 33 patients (11.7 % ) who survived to be hospitalized for 15.36 days on average, and there are 6 patients ( 2.1 % ) who were discharged from the hospital. 2. Internal medicine disease is the major causative factor of out-of-hospital cardiac arrest. Among those internal medicine disease cases, the history showed hypertension, diabetes mellitus, and heart diseases are the main causes of out-of-hospital cardiac arrest. Patients who are older than 65 years old are the main age groups, accounting for 67.7% of these cases. 3. The pre-hospital admission factors which affect the prognosis after the Emergency Department (ED) are the place of the accident, whether there are witnesses, scene process time , total reaction time , whether automatic external defibrillation was used, and whether people at the scene used CPR. 4. The post-hospital admission factors which affect the prognosis after the ED are initial cardiac rhythm, body temperature, pupil size , dose of epinephrine, whether defibrillation was used, the time of applying emergency first-aid, and medical expense. 5. The percentages of return of spontaneous circulation and survival rates in the study are lower than those of past studies of Taipei City and National Taiwan University Hospital. The possible factors are probably related to differences between rural and urban areas in the quality of emergency medical service systems (EMSS), and healthcare training. 6. From now on, in addition to improving the first-aid continuous monitoring system, we should also enhance EMT related training, and actively educate people to understand and learn CPR, so that comprehensive first-aid systems are available everywhere to effectively increase the success rate of first-aid.

Chest compressions in cardiopulmonary resuscitation are of utmost importance although not without a risk. Many injuries are described but the incidence of these is hard to define due to methodological differences. It is strenuous to perform chest compressions and therefore mechanical chest compressions have been looked upon with interest. This thesis presents new insights on the panorama and incidence of injuries in modern CPR and a comparison of safety and efficacy between manual chest compressions and mechanical chest compressions with the LUCAS™ device. We also evaluated if computed tomography could be an aid in the detection of these injuries. Two pilot trials were conducted and one presented no difference in early survival with 26% and 31% having return of spontaneous circulation when comparing manual chest compressions with the LUCAS device in out-of-hospital cardiac arrest. The other revealed no difference in autopsy-detected injuries. A third multicentre autopsy trial revealed that in patients treated with manual chest compressions 78.3% had at least one injury and 63.9% had at least one rib fracture. The corresponding numbers for patients treated with the LUCAS device was 92.8% (p = 0.002) and 77.7% (p=0.022). Sternal fractures occurred in 54.2% and in 58.3% of the cases treated with manual chest compressions and the LUCAS device respectively (p = 0.556). The median number of rib fractures was 7 in the group receiving manual chest compressions and 6 in the group receiving chest compressions with the LUCAS device. In 31 cases a computed tomography was conducted prior to autopsy and we found a very strong correlation in the discrimination of patients with or without rib fractures (kappa=0.83). Mean difference between the two methods in detecting rib fractures was 0.16. The detection of other injuries did not have a strong correlation. In conclusion there is no difference in early survival between the two methods and mechanical chest compressions adds 14-15% more patients with rib fractures but the amount of rib fractures, sternal fractures and other injuries is equal. CT can aid but not replace autopsies in the detection of these injuries.

Syfte: Att kartlägga vårdpersonalens kunskapsläge samt utbildningsfrekvens i hjärtlungräddning på ett länssjukhus i Mellansverige, samt beskriva följsamheten till att registrera behandlade hjärtstopp till det svenska hjärt-lungräddningsregistret. Metod: Enkätstudie med kvantitativ ansats bestående av 177 respondenter samt även som en retrospektiv observationsstudie. Huvudresultat: Enskilda personer svarade rätt på alla kunskapsfrågorna men som grupp fanns det brister i kunskapen i hjärtlungräddning. Då man jämförde vårdpersonalens kunskap påvisades att i fyra av sju kunskapsfrågor fanns en signifikant skillnad i kunskap mellan den vårdpersonal som har mer regelbunden utbildning, än den som har mindre. De som hade mer regelbunden utbildning hade flera rätt. En signifikant skillnad påvisades även beroende på när man hade haft sin senaste HLR-utbildning, där de som haft sin utbildning nyligen hade flera rätt. Följsamheten hos vårdpersonalen till att registrera patienter som behandlats för hjärtstopp på sjukhus till det svenska hjärt-lungräddningsregistret, kan sammanfattas med att det brister i rapporteringen. Konklusion: Det är viktigt att skapa förutsättningar för frekventa utbildningar till vårdpersonal för att öka kunskap och beredskap i hjärt- och lungräddning, vilket även kan ses som ett kvalitetssäkringsarbete. Ett förbättringsarbete är nödvändigt för att förbättra följsamheten till registreringen. / Objective: To identify the healthcare professional´s knowledge and training frequency of cardiopulmony resuscitation in a county hospital in central Sweden, and compliance of the Swedish Register of cardiopulmony resuscitation. Method: Survey with quantitative approach consisting of 177 respondents, as well as a retrospective observational study. Main results: Individuals answered correctly to all knowledge questions, but as a group, there were deficiencies in the knowledge of cardiopulmonary resuscitation. When comparing healthcare professional´s knowledge it was demonstrated that in four of the seven knowledge questions it was a significant difference in knowledge between the health professionals who have more regular training than those with fewer. Those who had more regular education had more right answers. A significant difference was also detected depending on when they had their latest CPR training, where those who have had their education more recently also had more right answers. Compliance of healthcare professional´s to register patients treated for cardiac arrest in hospital at the Swedish CPR registry, can be summarized by the deficiencies in reporting. Conclusion: It is important to create conditions for frequent training to health professionals to increase the knowledge and preparedness in CPR, which can also be seen as a quality assurance work. An improvement is necessary in order to improve compliance to registration.
