The purpose of this study was to provide basic data for the improvement of the guidelines and training programs regarding the cardiopulmonary resuscitation performance of bystanders who can respond to the incidents in earlier times as the first responder of the cardiac arrest incident, by reviewing the performance of basic CPR and the influencing factors after providing 70 students of Department of Emergency Medical Technology with the CPR training. For the purpose of the study, the collected data were computerized and analyzed by SPSS-WIN program(ver. 10.1). The results for this study were as follows The duration of session between the groups in the BLS CPR were 3 minutes and 36 seconds, 2 minutes and 32 seconds respectively. The average compression number per minute were 24.3 times and 33,2 times respectively(p=.000), and the average compression rate per minute were 112 times and 122 times respectively(p=.000). The average ventilation number per minute were 3.54 times and 5.1 times respectively(p=.000). The errors in compression "Too shallow" were 20.73 times(34.6%) and 23,23 times(38,7%) out of 60 times in 4 cycles with the standard of 38 nun. In CPR performance results according to gender in the first episode, males showed better results in compression depth as 41.5 mm comparing to females average 38.2 mm(p=.015). When ventilation results were compared according to the use of FS, the average ventilation number per minute, total ventilation per minute and the average volume per episode were significantly higher when FS was not used(<.040), There was no significant difference in ventilation accuracy between two groups. According to the results, we need to improve and distribute portable barrier devices, and to be familiar with those devices. We need to enforce ventilations as well as to include compressions so that faster and more accurate CPR can be performed. Additionally, we need to exclude ventilation only cases, minimize the interference time of chest compression due to inaccurate ventilation, simplify or minimize the complicatedness of CPR performance and responding time related to breathing, provide first responders with various training programs such as initial assessment and ventilations only, or initial assessment and chest compression-only CPR and than provide advanced training with AHA BLS education including CPR for more than two people according to CPR skills and target characteristics.

본 연구는 심폐소생술 시 착용하는 마스크의 유형에 따라 심장압박의 정확도, 피로도 및 생리학적 변화를 파악하고자 한다. 연구는 2022년 5월 9일부터 12일까지 D대학교 응급구조과 재학생 중 BLS provider를 소지하고 있는 학생 총 24명을 대상자로 선정하여 수술 마스크(Dental mask), 미세입자 94%차단마스크(KF94 mask)를 각각 12명씩 착용하고 총 7회에 걸쳐 2분간 심폐소생술을 실시하였다. 연구 결과, 마스크 유형에 따른 구조자의 가슴압박의 질 분석에는 KF94를 착용한 그룹에서 압박속도(F=24.91, p<.001),와 손의 위치불량(F=14.54, p=.024)에서 유의한 차이를 보였고, 피로도를 분석한 결과에서는 Dental mask그룹(F=51.16, p<.001)과 KF94그룹(F=63.49, p<.001) 모두에서 유의한 차이를 보였다. 생리학적 변화를 분석한 결과에서 심박동수를 살펴보면, Dental mask그룹(F=34.79, p<.001)과 KF94그룹(F=35.55, p<.001) 모두에서 유의한 차이를 보였고, 호흡수 측정결과에서도 Dental mask그룹(F=25.02, p=.001)과 KF94그룹(F=23.03, p=.002) 모두에서 유의한 차이를 보였다. 따라서 현장활동의 가장 중요한 심폐소생술시에는 효율적인 가슴압박의 정확도와 구조자의 피로도 및 생리학적 변화의 감소를 위해서는 구조자의 유형에 따른 개인보호장비를 착용하는 것이 필요할 것이다.

The transcranial Doppler(TCD) is a technique for measuring blood flow velocity of intracranial and extarcranial arteries. This examination based on Doppler effect which was first formulated in 1842 by the Austrian physicist Christian Doppler. In 1982, Rune Aaslid first maked 2MHz pulsed probe and recording intracranial vessels with transcranially. There are six criteria utilized in gaining positive identification of the intracranial vessels. The six criteria are as follows l)acoustical windows 2)depth of sample volume 3)direction of flow 4)spatial relationship of ACA and MCA bifurcation 5)mean velocity and 6)response common carotid artery compression and/or oscillation test. The affected factors for TCD examination are angle of insonation, posture of subject, age, gender, hematocrit, metabolic factors, and cardiac output. Clinical application of TCD are detection of stenosis, occlusion, emboli, thrombsis in intracranial and extracranial arteries and evaluation of cerebral arterovenous malformation, collateral capacity in the circle of Willis, ischemia cerebrovascular disease, stroke patient and vertebrobasilar system.

Insertion of an epicardial pacemaker is a useful treatment for pediatric patients with an abnormal heart rhythm. However, there are limitations and concerns when implanting epicardial pacemakers in infants and neonates due to their small body size. We report a patient who experienced rare complications after implantation of a permanent pacemaker.

Purpose : This study was to examine the knowledge and attitude about cardiopulmonary resuscitation(CPR) for nursing students, and to basic data with CPR education program for nursing student. Method : 128 nursing students filled out a self-administered questionnaires. The data were collected by CPR knowledge and attitude modified by the authors based on Kim's inventory (2008). Result : Nursing students weren't knowledgeable nor confident of CPR. But they had positive attitude about as a first responder. Conclusion : Intensive education by the level of knowledge should be provided for nursing students to master the knowhow of CPR, especially cardiac compression, and evaluation should be reinforced as well. And an education should be offered to enhance their confidence CPR performing CPR.

저자들은 1991년부터 1996년까지 5년간 지연 흉골 폐쇄를 시행한 20명의 환자를 분석하고 추적 조사 하였다. 남녀비는 11:9였고 평균연령은 6.4개월(범위 7일-5년)이었다. 적응증으로는 개심술후 심근부종에 기인한장치한 불안정한 혈역학적 상태로 인한 것이 15례로 가장 많았고, 심폐기 이탈 불가로 심실 보조 장치를 경우에서가 3례, 폐동맥 밴딩술 후 저산소증으로 인한 것이 2례 등이었다. 흉골 봉합은 술후 평균 102시간(범위 4-213시간)에 이루어졌으며 시행 후 중심 정맥압의 유의한 상승이 관찰되었다. 종격 동염, 환부 감염 등은 없었으며 2례에서 패혈증이 관찰되었다. 5명이 사망하였고 생존환자 15명중 2명 이 술후 추적관찰 기간 중 사망하였다. 누적 생존률은 1년과 2년에서 각각 65.0%였다. 지연 흉골 봉합 은 혈역학적으로 불안정한 심장을 감압하는 좋은 방법이며 성공적인 결과를 얻기 위해서는 적응증에 대한 신중한 고려가 선행되어야 한다고 생각된다.

Objective: Performing high quality cardiopulmonary resuscitation (CPR) is important for improving the survival rate with a good neurological outcome and fewer complications. The retention of accurate CPR knowledge is essential for providing high quality CPR. This study examined the effects of chest compression only CPR training on the retention of correct CPR knowledge. Methods: In December 2016, an interview survey to target the study population was conducted by trained interviewers, using a structured questionnaire. The respondents' general characteristics, status of CPR education, and knowledge and willingness regarding CPR were investigated. Pearson's chi-square tests and multivariate logistic regression analyses were used to determine which education-related factors affected the correct skill knowledge of performing CPR. Results: Among the respondents, there are 80 persons (17.4%) who answered correctly in the questions regarding the skills of performing CPR. The respondents who had a willingness to perform CPR to family and strangers were 90.2% and 44.9% respectively. Through multivariable analysis, the factors related to correct skill knowledge in performing CPR in the didactic with practice group were people who had undergone CPR training within 2 years (odds ratio [OR], 2.293; 95% confidence interval [CI], 1.311-4.009), and person who had undergone chest compression only CPR training (OR, 2.044; 95% CI, 1.033-4.042). Conclusion: Chest compression only type of CPR training and the experience of CPR education within 2 years were associated with accurate skill knowledge of performing CPR.

This study proposes an algorithm for removal of CPR artifact in order that automated external defibrillator (AED) can effectively diagnose ECG rhythm during cardiopulmonary resuscitation (CPR). Current AED required to interrupt chest compression for reliable rhythm analysis to avoid the effect of artifacts produced by CPR. However even temporarily interruption of chest compression during CPR adversely affects the probability of restoration of spontaneous circulation (ROSC) and survival after the delivery of the shock. Therefore, we proposed a method for removal of CPR artifacts using least mean square (LMS) filter. The removal of the CPR artifacts would enable compressions to continue during AED rhythm analysis, thereby increasing the likelihood of resuscitation success. It was tested on 31 segments of shockable and 300 segments of non-shockable ECG signals recorded from three pigs during CPR. In the result, sensitivity (Se) and specificity (Sp) analysis on the test segments showed values of Se = 3.2%, Sp = 66.0% and Se = 96.8%, Sp = 98.7% in the case of unfiltered and filtered signals during CPR. In conclusion, it was shown that the proposed method can be a useful tool to exactly diagnose the ECG rhythm during the CPR.
