The AED (Automated External Defibrillator) is not evaluated for spatial accuracy and temporal availability even if it is located within a building or a specific area that needed necessary to partition by spatial analysis and location allocation analysis. As a result of the analysis, the spatial analysis was performed using the existing public data of AED with applied the GIS location analysis method. A public institution (119 safety center, police box) was selected as a candidate for a public AED base that can operate 24 hours a day, 365 days a year according to the characteristics of each residential area. In addition, Thiessen Polygons were created for each candidate site and divided by regions. In the analysis of the service was analyzed regional in terms of accessibility to emergency medical services in consideration of the characteristics of AED, that emergency vehicles could arrive within 4 minutes of the time required for emergency medical treatment in most areas of the study area, but it did not areas outside of the city center. As a result, It was found that the operation of the AED base service center centered on vehicles of public institutions is effective for responding to AED patients at night and weekend hours. 19 Safety Center under and police box the jurisdiction of Daegu City to establish an AED service center for public institutions, location-based distance, attribute analysis, and minimization of overlapping areas that the method of using a vehicle appeared more efficient than using the existing walking type AED.

Purpose: This study aimed to assess defibrillator pad positioning by the general public and healthcare providers during basic life support (BLS) renewal education (RE). Methods: A total 130 subjects performed defibrillation using an automated external defibrillator (AED) equipped with electrode pads developed by the researchers and male resuscitation manikins, in order to assess electrode pad placement (EPP) before BLS RE. Subjects included 54 Healthcare providers (HP) and 76 members of the general public (GP). Results: The apex EPP was positioned in the risk area (RA), more than 5 cm distant from the area recommended, by 63.2% of the GP (n = 48). The apex EPP was positioned in the RA by 44.4% of the HP (n = 23). The distance from the apex (GP $5.27{\pm}2.21cm$, HP $4.18{\pm}1.71cm$) was statistically significant, using Student's t-test. Conclusion: For both GP and HP, apex EPP was significantly in error. Thus, to prevent defibrillation failures, EPP education and practice for GP and HP in all BLS education programs should be improved, and incorrect Korean cardiopulmonary resuscitation guidelines and related literature should be revised and corrected.

Objective: The increasing number of people living in high-rise apartments may result in a delayed response from emergency medical technicians called out for an out-of-hospital cardiac arrest, making the role of apartment managers as the first responders extremely important. This study investigated whether automated external defibrillator (AED) placement influences the willingness of apartment managers to perform cardiopulmonary resuscitation (CPR) and use an AED. Methods: A cross-sectional target population-based survey was conducted in Daegu, July 2016. Questionnaires were sent to apartment managers working in apartments with more than 500 households. The general characteristics of the respondents, status of CPR education, and knowledge about and willingness to perform CPR and use an AED were investigated. Results: Of the 1,445 respondents, 758 (52.5%) worked in apartments with AEDs, of which 77.8% and 70.8% were willing to perform CPR and use an AED, respectively, compared with 68.1% and 60.0% of respondents who worked in apartments without AEDs. After adjusting for potential confounders, AED placement was associated with the willingness to perform CPR (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.04-1.71) and use an AED (OR, 1.39; 95% CI, 1.10-1.75). Prior CPR training and accurate knowledge of CPR skills were also associated with the willingness to perform CPR and use an AED. Conclusion: Placing AEDs in high-rise apartment buildings and providing refresher CPR education for maintaining CPR skills will be necessary to support apartment managers in their role as first responders.

자판기가 단순히 판매장비로만 역할을 한정해서는 안 된다. 자판기의 사회적 책임 측면에서 볼 때 '좋은 일'들을 하는데도 얼마든지 활용될 수 가 있다. 하고자 한다면 좋은 일에 쓰는 모금을 한다거나 유괴방지 및 범죄예방 시스템을 채택할 수 있다. 심지어는 사람의 생명까지 구해내는 역할을 할 수도 있다. 자판기에 AED (Automated External Defibrillator-일명 "심실제새동기"라고도 함. 이하 AED)를 부착하면 갑작스런 심장마비가 발생한 환자를 구해 낼 수 있다. 자판기의 사회적 책임강화에 산업의 미래를 걸고 있는 일본에서는 한창 AED 장착 자판기 보급을 늘리고 있다. 얼마 전까지만 해도 이런 일본의 사례를 남의 나라 얘기로 '강건너 불구경' 하듯 했던 게 사실이다. 그러나 국내도 최근 각 공공장소에 AED 보급 필요성이 높아지고 있다. 특히 응급의료에 관한 법률이 개정됨에 따라 다중이용시설에 대한 설치가 법제화가 된지라 AED설치가 늘고 있다. 이런 환경 변화는 자판기에 있어서도 좋은 기회이다. AED설치를 위해 별도의 공간을 할애할 필요가 없어 자판기에 장착하면 공간활용에 있어 제격이다. 게다가 자판기의 공공성을 강화할 수 있다는 점에서 도입 효과가 크다. 이런 점에서 볼 때 국내도 이제 AED 장착 자판기 보급을 서둘러야 할 시점이다. 일본도 하는데 우리가 못할 이유가 없다. 일본이 AED 장착 자판기를 늘리는 이면에는 산업계의 고도의 실익 계산도 깔려 있다. 국내도 AED 장착 자판기 보급을 늘려야하는 이유 및 시장 과제를 집중 분석해 봤다.

This study examined the level of knowledge, attitude, and performance ability of automated external defibrillator (AED) and cardiopulmonary resuscitation (CPR) among university students who were not in health-related majors and to explore the relationships among these variables. In this study, 291 students were recruited from 3 universities in D city. Among them, 77.0% had ever seen or heard of AED and 61.9% did not know how to use it. The levels of knowledge, attitudes and performance ability differed significantly according to the CPR training experience and AED awareness (p<.002~.001). The performance ability showed significant correlations with knowledge (r=. 42, p<.001) and attitude (r=. 55, p<.001) of AED and CPR. These findings suggest that future AED and CPR training programs should be developed to promote a positive attitude towards the willingness to perform AED and CPR as well as to increase the participants' confidence by repeated training.

This study compares the rapidity and subjective convenience of T-AED and SC-AED for health care providers and the general public. Subjects were randomly allocated to T-AED (n=77) and SC-AED (n=79) groups. Each group conducted defibrillation, with subsequent measurement of the rapidity of defibrillation in peri-shock pause, pre-shock pause, hesitation pause, and post-shock pause. Defibrillation and chest compression delay times for both equipment were analyzed by t-test. On conclusion of the experiment, subjects answered a questionnaire on the subjective convenience of defibrillation, as measured for confidence, convenience, and clear decision. Comparisons of subjective convenience analyzed by t-test revealed significantly shortened peri-shock pause (11.22s), pre-shock pause (11.04s), and hesitation pause (2.15s) in the SC-AED group, as compared to the T-AED group (p<0.001). However, no significant differences were observed for post-shock pause values. Comparing subjective convenience, confidence (T-AED: 7.62±1.25VAS vs. SC-AED: 7.80±0.98VAS, p=0.358) was not significant, whereas convenience (T-AED: 7.05±1.36VAS vs. SC-AED: 8.95±0.89VAS, p<0.001) and clear decision (T-AED: 6.58±1.73VAS vs. SC-AED: 9.08±0.98VAS, p=0.001) showed statistically significant differences. Our results indicate that compared to T-AED, SC-AED has significantly shortened pauses. Moreover, it is more convenient for the user, and significantly aids in clear decisions.

This study aims to make a comparison of educational effectiveness between instructor-centered learning and video self-instruction(VSI) about automatic external defibrillator(AED) for high school girls in order to help select an effective teaching method concerning AED. A total of 59 high school girls (29 for the experimental group, 30 for the control group) in J Province participated in this study from July 7 to 14, 2010. The analysis was carried out by using an SPSS WIN 12.0 Version program. After the AED instruction, the knowledge increased more in the experimental group (1.72) than that in the control group (1.60); self-confidence increased more in the experimental group (1.58) than that in the control group (1.46); and accuracy of technical performance increased more in the control group (5.46) than that in the experimental group (4.20). The experimental group (5.68) was more satisfied with AED instruction than the control group (4.95). Since video self-instruction proved to be more educationally effective than instructor-centered learning in most areas, it is necessary to apply video self-instruction to AED instruction in the future. However, further researches are necessary to see if video self-instruction is effective.

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.
