Abstract

This study was conducted to examine the differences of the quality of chest compression between 10 cm higher position of rescuer's knee from the bottom and its bottom position during implementation of CPR. It selected randomly subjects out of 66 students who attend the Dept. of Emergency Medical Technology in G college, G metropolitan city as the first grader and divided them into 31 experimental group and 32 control group from Nov. 8 to 9, 2011. Mattress was spread 10 cm higher from the bottom(material: B4 Copy Paper) and on the bottom(material: PVC, size: $185{\times}125{\times}0.65cm$) and only chest compression was conducted for 2 minutes. Experiment was conducted with 1 Resusci Anne mannequin and the results of experiment were recorded with Laerdal PC Skill Reporting System. Data collected were analyzed with $x^2$-test and Fisher's exact probability test using SPSS 14.0 for Window, Mann-Whitney U-test, and Wilcoxon signed rank test. As a result of the study, it was found that 10 cm higher position of rescuer knee from the bottom than the bottom position and group below 170 cm in their height and 65 kg in their weight were more effective in proper depth of chest compression and average chest compression depth.

본 연구는 심폐소생술 시행 시 구조자의 무릎이 바닥으로부터 10 cm 높은 위치와 바닥 위치 간에서 흉부압박의 질에 차이가 있는지를 알아보고자 시행하였다. G광역시의 G대학 응급구조과 1학년 재학생으로 심폐소생술 교육 과정을 이수한 66명 중, 무작위추출과정을 통해 2011년 11월 8일부터 9일까지 실험군 31명, 대조군 32명으로 선정하였다. 바닥으로부터 10 cm 위치(재질: B4 Copy Paper)와 바닥 위치에는 공통으로 매트리스(재질: PVC, 사이즈: $185{\times}125{\times}0.65cm$)를 깔고 2분 동안 흉부압박 만을 시행하였다. 실험 처치는 Resusci Anne 마네킨 1대를 사용하였으며, Laerdal PC SkillReporting System으로 시행결과를 기록하였다. 수집된 자료는 SPSS 14.0 for Window으로 $x^2$-test와 Fisher's exact probability test, Mann-Whitney U-test, Wilcoxon signed rank test를 사용하였다. 연구결과, 심폐소생술 구조자의 무릎이 바닥으로부터 10 cm 높은 위치가 바닥 위치보다 흉부압박 적절한 깊이(회), 평균 흉부압박 깊이(mm)가 더 효과적이었는데, 신장 170 cm 이하 그룹, 몸무게 65 kg 이하 그룹에서 흉부압박의 적절한 깊이(회), 평균 흉부압박 깊이(mm)가 효과적 이었다.
