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.

Purpose: The purpose of the study was to investigate knowledge and attitudes of students majoring in health-related fields toward automated external defibrillator (AED) and to identify the influencing factors of knowledge and attitudes in AED use among the students. Methods: Data were collected from 346 students and analyzed using descriptive statistics, t-tests, one-way ANOVA, post hoc $Scheff{\acute{e}}$ test, Pearson's correlation coefficient, and hierarchical multiple regression analysis, with SPSS Win 20.0 program. Results: Overall knowledge of AED in health-related major students, except paramedics and physical therapy was relatively low while attitudes were at moderate level. There were statistically significant differences in knowledge according to age, grade, major, cardiopulmonary resuscitation (CPR) awareness, exposure to AED and CPR education; and differences in attitude according to major, health status, health awareness, CPR awareness, exposure to AED, and CPR education. Significant factors explained 63% of knowledge on AED (F= 43.96, p<.001) and 37% of attitudes on AED (F= 15.84, p<.001). Conclusion: The study findings suggest that systemic education programs on AED should be implemented during undergraduate curriculum to improve survival rate of sudden cardiac arrest.

Purpose : The purpose of this study was to investigate the effectiveness of cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) education for school teachers by questionnaire survey including the knowledge, self-efficacy and skills of CPR and AED after basic life support (BLS) education. Methods : The subjects were school teachers who participated in BLS education from 24 Nov. to 1 Dec. 2012. They completed the self-reported questionnaire based on BLS skill checklist. Results : There was a statistically significant increase in the knowledge(p <.001), self-efficacy (p <.001) and skills(p <.001) of CPR and AED after BLS education. The correlation existed conspicuously between knowledge versus self-efficacy(r =.409, r =.387), knowledge versus skill(r =.442, r =.084), and self-efficacy versus skills (r =-.148, r =.047) of CPR and AED before and after BLS education. Conclusion : After BLS education, most of the participants found the program was easy and useful to perform. Participants had the willingness to do CPR and AED and wanted to teach BLS to others. It is necessary to provide BLS education for school teachers by systematic approach.

Purpose: The purpose of this study is to evaluate the interrupted chest compression time during the use of an automated external defibrillator (AED) depending on different AED practice training methods, and to report differences in self-efficacy before and after training. Methods: We enrolled university freshmen who have had cardiopulmonary resuscitation (CPR) training but have not or have had AED training but over 6 months. We examined differences between the group that practiced only shockable rhythms during training and the group that practiced both shockable and non-shockable rhythms. Results: A total of 72 individuals participated in this study, with 36 individuals each in the control and experimental groups. There was no statistically significant difference in the proficiency of AED usage between the two groups. In non-shockable cases, the experimental group showed shorter chest compression interruption time than the control group (2.30±1.21sec vs. 3.16±1.73 sec; p<0.01). In terms of self-efficacy before and after training, both groups showed higher self-efficacy after than before training. Conclusion: Individuals who underwent training that provided practice on both shockable and non-shockable rhythms had a shorter interrupted chest compression time when using the AED.

Virtual training is a kind of training that proceeds as if it were a real situation. In recent years, there has been a growing demand for experiencing a situation in which a virtual reality technology has not been experienced directly in the real world due to the rapid development of the technology. Especially, safety education is very necessary in Korea where safety accidents are caused by many disasters. Therefore, simulation of disaster response training using virtual reality is more urgent than ever. Although the automatic defibrillator is the medical device that is most needed to rescue patients with cardiac arrest, few people know how to use it. Therefore, there are very few cases where the use of automatic defibrillators has saved the patient's life in Korea. The proposed Automated External Defibrillator virtual training system enables immersive and experiential training in real situations and effective training at low cost.

This study was conducted to examine the awareness of workers in public institutions of automated external defibrillators, their usage intention and related educational experience in an effort to increase the efficiency of education and the rate of automated external defibrillator usage in emergency situations. The subjects in this study were 243 selected. male and female adults who worked in public institutions in Gangwon Province. A survey was conducted from June 13 to August 21, 2016. The statistical analysis was based on the frequency analysis and the $X^2$-test. There were significant differences among the public institution workers awareness of how to use an automated external defibrillator according to gender (${\chi}^2=6.32$, p<0.05) and academic credentials (${\chi}^2=5.91$, p<0.05). Additionally, there were significant differences in usage intention according to academic background (${\chi}^2=5.70$, p<0.05). The most common reason for having no intention to use an automated external defibrillator for patients with cardiac arrest was that the respondents did not know how to use it (31.5%). There were also significant differences in educational experience with automated external defibrillators according to age (${\chi}^2=6.15$, p<0.05), academic credentials (${\chi}^2=11.56$, p<0.01) and career (${\chi}^2=11.92$, p<0.01). The most common form of education that the workers received pertaining to automated external defibrillators was a combination of theoretical and practical education, which represented 55.9%. The findings of the study seem to suggest that workers in public institutions used by many people must receive compulsory standard education regarding automated external defibrillators and try to boost the revival rate of patients with cardiac arrest in real emergency situations.

Purpose: The purpose of the study was to compare the ability of college students to use automated external defibrillators (AED) and to provide a basic data for helping laypersons easily apply the AED. Methods: The subjects were randomly assigned to instruction groups. One group was instructed by pictures (group P), one by videos (group M), and one by telephone dispatchers (group D), Without employing cardiopulmonary resuscitation, a single rescuer was asked to apply defibrillation to a mannequin for practice in accordance with the instructions assigned to each group. Results: Regarding the proper pad attachment of the AED, group P followed the instruction $0.31{\pm}0.47times$, group M, $0.81{\pm}0.40times$, and group D $0.69{\pm}0.47times$. Regarding the instruction of taking the hand off a patient for analyzing cardiac rhythm and the instruction of taking the hand off a patient before defibrillation, group P did not follow the instruction; group M followed the instructions $0.50{\pm}0.51times$; and group D followed all instructions at all times. Conclusion: If a dispatcher gives real-time instructions for using an AED to laypersons wtih no experience at the time of AED use, the quality of laypersons' AED use will greatly improve.
