Abstract

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.

일반인이 심정지를 신속하게 인지하는 것은 심정지 생존에 중요한 첫 단계이다. 본 연구는 심정지 상황에서 발생하는 심정지 호흡을 기존 강의식 교육과 동영상 교육으로 시행한 후, 심정지 인지를 분석하여 효과적인 교육방법을 파악하고자 연구를 수행하였다. 연구설계는 연구대상자를 강의식 교육과 동영상 교육으로 무작위로 배정하여 교육을 수행한 후 심정지인지를 비교한 무작위 대조군 연구이다. 연구기간은 2015년 10월 30일부터 10월 31일까지 시행하였으며, 연구대상은 15세 이상 청소년 104명으로 실험군 52명, 대조군 52명으로 선정하였다. 연구결과, 반응이 없고 호흡이 없는 동영상에서 실험군과 대조군의 차이를 보이지 않았다(p=0.741). 하지만 반응이 없고 심정지 호흡을 보이는 동영상에서는 실험군 중 심폐소생술시행이 43명(82.7%), 대조군 중 심폐소생술 시행이 33명(63.5%)으로 유의한 차이를 나타냈다(p=0.006). 이러한 결과를 통하여 심폐소생술 교육 시 동영상으로 심정지 호흡을 교육하는 것이 기존 강의식 교육에 비해 심정지 인지를 향상시키는 것을 파악할 수 있었다.
