Cardiopulmonary resuscitation(CPR) is an important clinical technique performing artificial ventilation and chest compression on a patient under emergent situation before arriving in hospital. Since the quality of CPR significantly affects the survival rate, it would be of great advantage to monitor respiration in real time during CPR. However, currently applied respiratory air flow transducers are difficult to apply with sensing elements in the middle of the flow axis. The present study developed a new turbulent air flow transducer conveniently applicable to CPR. Abrupt changes in diameter of the flow tube generated turbulence in air flow, thereby pressure difference was obtained to estimate the air flow rate, with no physical object on the flow plane. Expiration and inspiration were separated by the direction of the pressure difference, resulting in good symmetry. Pressure-flow relationship was tested on a quadratic model, which provided accurate enough estimation results. Therefore, the present turbulent air flow transducer seemed appropriate to monitor respiration during CPR.

Purpose: The aim of this study is to investigate the quality of basic life support (BLS) information for primary Korean-speaking individuals on the internet. Methods: Using the $Google^{(C)}$ search engine, we searched for the terms 'CPR', 'cardiopulmonary resuscitation (in Korean)' and 'cardiac arrest (in Korean)'. The accuracy, reliability and accessibility of web pages was evaluated based on the 2015 American heart association(AHA) guidelines for CPR & emergency cardiovascular care, the health on the net foundation code of conduct and Korean web content accessibility guidelines 2.1, respectively. Results: Of the 178 web pages screened, 50 met criteria for inclusion. The overall quality of BLS information was not enough (median 5/7, IQR 4.75-6). 23(36%) pages were created in accordance with 2010 AHA guidelines. Only 24(48%) web pages educated on how to use the automated electrical defibrillator. The attribution and transparency of the reliability of pages was relatively low, 20(40%) and 16(32%). The web accessibility score was relatively high. Conclusion: A small of proportion of internet web pages searched by Google have high quality BLS information for a Korean-speaking population. Web pages based on past guideline were still being searched. The notation of the source of CPR information and the transparency of the author should be improved. The verification and evaluation of the quality of BLS information exposed to the Internet are continuously needed.

Purpose: The purpose of the study was to evaluate the ergonomic risk factors of 119 emergency medical technicians (EMT) with musculoskeletal disorders, performing emergency medical services (EMS) procedures in a firefighter combat challenge. Methods: The evaluated EMT procedures were cardiopulmonary resuscitation (CPR) & intubation, trauma patient assessment, and intravenous (IV) injection. Measurement of working posture was done during training. Results: In CPR & intubation, OWAS-score was 2 (mean 1.9, maximum 4), requiring correction action, while REBA-score was 11 (mean 7.28, maximum 11), requiring immediate improvement. In trauma patient assessment & IV injection, OWAS-score was 4 (mean 2.9, maximum 4), requiring immediate correction action, while the REBA score was 7 (mean 7.5, maximum 11), requiring improvement. Conclusion: Both OWAS score and REBA-score showed improvement of posture and high-risk of musculoskeletal disorders. Occupational health management in EMS procedures during combat challenge and effective injury prevention program in fire stations are warranted.

Purpose: This study aimed to assess the awareness of good Samaritan law and attitude toward basic life support (BLS) of university students. Methods: A 29-item questionnaire survey was conducted among 147 students in A university. The participants were freshmen and sophomores who had received cardiopulmonary resuscitation (CPR) training in middle or high school. Statistical analysis was carried out using SPSS 21.0. Results: The majority (85%) of the participants knew about the good Samaritan clause in the Emergency Medical Service Act, but only about half (58.5%) knew about the Non-rescuer Act. Almost all of the patients said they would administer CPR to patients and showed a positive attitude toward BLS (3.74±0.40). Conclusion: Greater help attitude was exhibited by those who knew the good Samaritan law. These findings suggested that such education may increase their likelihood or helping in emergencies.

Purpose: There has been an increase in the number of prehospital cardiac arrests due to the increasing number of cardiovascular diseases and the increase in the average age of the population. We performed this study to identify the proper resuscitation technique and AED to be used to increase the survival rate in prehospital cardiac arrests. Methods: This studied 159 victims with prehospital cardiac arrests(VF or VT rhythm) by EMT's Reports from January to August, 2005. Results: 108 of 159 victims(67.9%) were shocked by AED. Eighty of 159 victims(50.9%) were recorded with AED shock in prehospital cardiac arrests. A number of shocks is averaged 2.19; 46.2% of one-shock and 86.1% of 1-3 shock. EMS first-tier response interval from time of dispatch to scene arrival was 5.88 minutes, from scene arrival to scene start was 7.36 minutes, from scene start to hospital admission was 9.91 minutes and from scene arrival to AED shock was 6.84 minutes. EMT provided advanced care to prehospital cardiac arrests: 97.5% in CPR, 10.1% in advanced airway management, 67.9% in AED shock. Conclusion: With the increase in cardiovascular disease and old age, the number of prehospital cardiac arrests has risen gradually. However, there were lack of CPR by bystander, defibrillation and advanced cardiac life support(ACLS) in prehospital stage. To improve the adequacy of basic life support and to increase the performance of ACLS, especially AED, we must create challenges to develop new protocols in prehospital care.

이 연구는 소아 심폐소생술 중 새로운 가슴압박 방법을 활용했을 때, 가슴압박의 질을 비교하여 효과적인 심폐소생술을 할 수 있도록 하고자 시행되었다. 무작위 교차방법(Randomized Crossover Design)에 의한 실험 연구로 BLS Health Care-Provider 자격을 이수한 28명의 응급구조사를 대상으로 가슴압박 시행 시 깊이, 속도, 압박 대 이완의 비율, 용이성, 안정감 등을 측정하였다. 수집된 자료는 SPSS Ver. 23.0 for Win 통계프로그램을 이용하여 분석하였다. 본 연구의 결과 를 종합해 보면, 소아 심폐소생술에서 가슴압박 시행 시 새로운 가슴압박법을 이용한다면 가슴압박의 질적 지표가 향상되었음을 알 수 있었다. 기존의 방법을 고수하는 것도 좋지만 새로운 가슴압박 방법을 통해 다양한 연령대와 환경요소에 대한 추가적인 연구를 바탕으로 임상적 활용의 가능성을 확인하는 것이 필요할 것이다.

본 연구는 2020년 1년간 수집된 심폐정지환자 세부상황표(2020년, 원시자료) 3,418건을 대상으로 하였다. 또한, 관련 법률과 지침을 조사하여 고찰하는 후향적 서술조사연구이다. 연구 결과, 첫째. '목격자에 의한 심폐소생술' 시행률 30.66%(1,047건)는 주목할 만한 결과로, 관련 법률 및 지침이 짜임새 있게 마련되어 있음을 짐작해 볼 수 있다. 둘째, '목격자에 의한 자동심장충격기 사용은 불과 0.10%(5건)에 불과한 것으로 나타났다. 이는 관련 법률 및 지침이 '구비 및 의무'에 다소 치우쳐 있기 때문으로 사료되며, 지역별 관련 대응 방법 모색의 전략적 차별성을 두어야 함을 시사한다. 셋째, 대구지역의 심정지 발생 장소는 가정이 71.97%(2,640건)로 나타났다. 향후 심정지 대응의 지역별 '맞춤전략' 및 '특별구급대'의 효율적 운영을 위하여, 원시데이터를 활용한 고급통계분석중심의 후속 연구가 필요하다.

Introduction: The importance of clinical skills training in traditional Korean medicine education is increasingly emphasized. Since the clinical skills tests are high-stakes tests that determine success in national licensing exams, it is essential to develop reliable multifaceted analysis methods for clinical skills tests in actual education settings. In this study, we applied the multifaceted validity evaluation methods to the evaluation results of the cardiopulmonary resuscitation module to confirm the applicability and effectiveness of the methods. Methods: In this study, we used internal consistency, factor analysis, generalizability theory G-study and D-study, ANOVA, Kendall's tau, descriptive statistics, and other statistical methods to analyze the multidimensional validity of a cardiopulmonary resuscitation test in clinical education settings over the past three years. Results: The factor analysis and internal consistency analysis showed that the evaluation rubric had an unstable structure and low concordance. The G-study showed that the error of the clinical skills assessment was large due to the evaluator and unexpected errors. The D-study showed that the variance error of the evaluator should be significantly reduced to validate the evaluation. The ANOVA and Kendall's tau confirmed that evaluator heterogeneity was a problem. Discussion and Conclusion: Clinical skills tests should be continuously evaluated and managed for validity in two steps of pre-production and actual implementation. This study has presented specific methods for analyzing the validity of clinical skills training and testing in actual education settings. This study would contribute to the foundation for competency-based evidence-based education in practical clinical training.
