Purpose: This study aimed to develop 360° virtual reality videos and common videos for cardiac arrest recognition. Methods: A sequential mixed methods study was conducted, using qualitative interviews (with a total of seven experts) and a quantitative survey. Results: First, the cardiac arrest situation should be developed within 2-3 minutes after witnessing the patient collapse, for each of the four cardiac arrest videos about apnea, gasping, seizure, gasping, and seizure. Second, the education program should be designed so that the education on cardiac arrest recognition can proceed before CPR practice begins. Conclusion: 360° virtual reality videos and common videos for cardiac arrest recognition can play an important role in the education of the general public about cardiac arrest experience.

Purpose: Education for children in South Korea is similar to that for adults, necessitating additional enhancements. Therefore, this study aimed to examine the effectiveness of fairy-tale books in cardiopulmonary resuscitation (CPR) education among kindergarten children. Methods: The study involved 64 kindergarten children enrolled in an affiliated kindergarten program were included. The participants were divided into an experimental group of 32 who received CPR education using picture books, and a control group of 32 who received education through traditional methods. Participant characteristics such as sex, age, height, weight, cardiac arrest awareness, and ability to request assistance were measured, and the collected data were statistically analyzed. Results: Following education, the experimental group showed significantly higher scores than the control group across all measures, including cardiac arrest recognition (2.25 vs. 0.34, p<.001) and consciousness assessment (1.81 vs. 0.09, p<.001). Additionally, in requesting assistance, the experimental group exhibited statistical superiority in phone usage (1.75 vs. 0.28, p<.001), situational explanation post-call (2.25 vs. 0.34, p<.001), and self-location explanation (0.84 vs. 0.00, p=.001). Conclusion: The use of fairy-tale books in CPR education enhanced cardiac arrest recognition and the ability to request assistance (EMS Activation) more effectively than the traditional educational methods among kindergarten children.

This study aimed to help build a quality control program to improve cardiac arrest treatment via analysis of medical records in a local tertiary general hospital to evaluate factors that influence clinical outcomes of in-hospital cardiac arrest. At first, the medical records of in-hospital cardiac arrest were analyzed, and targeted surveys about functional and structural factors associated with cardiopulmonary resuscitation (CPR) were conducted amongst the workforce in charge of cardiac arrest treatment. From January 2012 through June 2013, a total of 486 adult cases of in-hospital cardiac arrests, except for those occurring in the emergency room, were enrolled in this study. Among the patients, those of recovery of spontaneous circulation were 57.8%; 13.8% of patients were discharged alive; 8.9% of patients were discharged without significant neurologic sequela. Despite CPR is usually successful when administered as quickly as possible, in this analysis showed that prompt reaction after initial recognition was significantly lower in nurses compared with doctors. Analysis of survey results showed that confidence in performing CPR was significantly associated with the experience of CPR in doctors, while in nurses educational experience showed a correlation. In order to improve quality of in-hospital CPR system maintaining and increasing confidence of CPR performance is the most important factor. Therefore it can be helpful to develop and apply a phased, customized education program using training simulators as well as personalizing them to increase the personnel's confidence in CPR performance.

Cardiopulmonary resuscitation (CPR) is a series of life-saving actions that improve the chances of survival, following cardiac arrest. Successful resuscitation, following cardiac arrest, requires an integrated set of coordinated actions represented by the links in the Chain of Survival. The links include the following: immediate recognition of cardiac arrest and activation of the emergency response system, early CPR with an emphasis on chest compressions, rapid defibrillation, effective advanced life support, and integrated post-cardiac arrest care. The newest development in the CPR guideline is a change in the basic life support sequence of steps from "A-B-C" (Airway, Breathing, Chest compressions) to "C-A-B" (Chest compressions, Airway, Breathing) for adults. Also, "Hands-Only (compression only) CPR" is emphasized for the untrained lay rescuer. On the basis of the strength of the available evidence, there was unanimous support for continuous emphasis on high-quality CPR with compressions of adequate rate and depth, which allows for complete chest recoil, minimizing interruptions in chest compressions and avoiding excessive ventilation. High-quality CPR is the cornerstone of a system of care that can optimize outcomes beyond return of spontaneous circulation (ROSC). There is an increased emphasis on physiologic monitoring to optimize CPR quality, and to detect ROSC. A comprehensive, structured, integrated, multidisciplinary system of care should be implemented in a consistent manner for the treatment of post-cardiac arrest care patients. The return to a prior quality and functional state of health is the ultimate goal of a resuscitation system of care.

It is the first step to survive cardiac arrest for the general public to recognize cardiac arrest rapidly. The purpose of this study is to investigate the effective method of education by analyzing the degree of cardiac arrest recognition after performing the agonal breathing education in a video lecture or instructor-led lecture. The study subjects were assigned to either a video lecture or instructor-led lecture in a randomized way and were compared after the education according to the degree of recognition of cardiac arrest in the randomized controlled study. The study was conducted from October 30, 2015 to October 31, 2015. And the study subjects were 104 youths aged 15 years or older, of which 52 were selected as the experimental group and the remaining 52 as the control group. The results did not show a significant difference between these two groups when the subjects are given the video lecture where patients showed no reaction or sign of breathing(p=0.741). However, in the video lecture where there was no reaction of patients but still sign of agonal breathing, 43 people(82.7%) in the experimental group and 33 people(63.5%) in control group have successfully performed CPR and there has been a significant difference (p=0.006). Therefore, we could conclude that video lecture was more efficient than instructor-led lecture when teaching CPR.

Cardiac arrest is a critical medical emergency where immediate response is essential for patient survival. This is especially true for Out-of-Hospital Cardiac Arrest (OHCA), for which the actions of emergency medical services in the early stages significantly impact outcomes. However, in Korea, a challenge arises due to a shortage of dispatcher who handle a large volume of emergency calls. In such situations, the implementation of a machine learning-based OHCA detection program can assist responders and improve patient survival rates. In this study, we address this challenge by developing a machine learning-based OHCA detection program. This program analyzes transcripts of conversations between responders and callers to identify instances of cardiac arrest. The proposed model includes an automatic transcription module for these conversations, a text-based cardiac arrest detection model, and the necessary server and client components for program deployment. Importantly, The experimental results demonstrate the model's effectiveness, achieving a performance score of 79.49% based on the F1 metric and reducing the time needed for cardiac arrest detection by 15 seconds compared to dispatcher. Despite working with a limited dataset, this research highlights the potential of a cardiac arrest detection program as a valuable tool for responders, ultimately enhancing cardiac arrest survival rates.

Purpose: The first responder's role during a cardiac arrest scene is to initiate CPR. The AHA has recognized and included the first responder's role for improving the survival rate of cardiac arrest patients. Health personnel working in nursing, emergency care, dental hygiene, radiology, and ocular optics frequently confront sudden cardiac arrest while working. This study was to identify the relationship between the educational experience and recognition with the level of knowledge about CPR for college students. Method: Five hundred forty college students enrolled in the department of nursing science, radiological technology, ocular optics, emergency medical technician, or dental hygiene in Daejeon city were surveyed. The tool used was CPR knowledge developed by the authors based on a literature review including 2005 AHA's CPR guideline. Result: The higher educational experience of CPR was, the higher the level of knowledge. The knowledge of the students in nursing or emergency medical technician was higher than students in dental hygiene, radiology, and ocular optics. Conclusion: CPR class should be included in the curriculum for college students in order to improve their accuracy as a first responder to cardiac arresting patients.

Purpose: Acute nicotine poisoning by liquid nicotine in electronic cigarettes is becoming an increasing problem worldwide. The current systematic review aimed to determine the harm of acute nicotine poisoning by reviewing published case reports. Methods: An online literature search with PubMed, Embase, Cochrane Library, and KoreaMed database was performed to identify relevant studies addressing acute nicotine poisoning with electronic cigarettes. Two investigators searched the case reports written in English or Korean. Results: Twenty-six cases were included in this study. The routes of intoxication included ingestion in 18 cases, intravenous injection in three cases, subcutaneous injection in two cases, and ocular exposure in two cases. Ten cases had a cardiac arrest, and seven of them died. Seven out of 12 cases with intentional poisoning had a cardiac arrest. Nine children under 18 years were reported, and three of them had a cardiac arrest. Sixteen cases without a cardiac arrest recovered well, except for one case with sudden sensorineural hearing loss. Conclusion: The authors reviewed the risks of electronic cigarette liquid in terms of acute poisoning through a systematic review. The nicotine solution of an e-cigarette can be life-threatening in cases of acute poisoning. Therefore, active emergency treatment with early recognition is necessary. In addition, various management methods and regulations for preventing acute nicotine poisoning, such as restriction of distribution and nicotine concentration, should be considered.

Purpose: This study simulates cardiac arrest situations in 360° virtual reality video clips and general video clips, and compares the correlations between educational media and experience recognition. Methods: Experimental research was carried out on a random control group (n=32) and experimental group (n=32) on March 20, 2019. Results: The groups where participants were trained with the 360° virtual reality video clips and a higher score of experience recognition (p=.047) than the group where participants were trained with the general video clips. Moreover, the subfactors of experience recognition including the sense of presence and vividness (p=.05), immersion (p<.05). experience (p<.01), fantasy factor (p<.05). and content satisfaction (p<.05) were positively correlated. Conclusion: Enhancing vividness and the sense of presence when developing virtual reality videos recorded with a 360° camera is thought to enable experience recognition without any direct interaction.
