Abstract

Purpose : This study is equivalence experiment performed to test practice effects between experimental group from both left and right direction of mannequin and control group having practice from only right direction in cardiopulmonary resuscitation education. Methods : Subject of the research were total 71 elementary and middle school teachers in J province who had not experience to have cardiopulmonary resuscitation. They were divided into experimental group of 35 participants who practiced cardiopulmonary resuscitation from both right and left direction of mannequin on Dec. 27, 2009 and control group of 36 participants who performed cardiopulmonary resuscitation from only right direction of mannequin on Dec. 28, 2009. Collected data were analyzed by SPSS/PC+(version 14.0). Results : 1. There was no statistically significant difference by sex among general characteristics of the subjects. 2. According to the quality of chest compression performed from the right direction of mannequin, experimental group showed better results in proper depth (time), insufficient depth (time), too lowered compression position (time) and inexact position (time) than control group(p<.05). In the quality of chest compression from the left side of mannequin, experimental group performed better results in proper depth (time), insufficient depth (time), inexact compression position (time) and mean chest compression depth(mm) than control group(p<.05) and also in more left-centered compression position (time) than control group(p<.001). 3. The quality of chest compression by experimental group, the right side of mannequin was superior in proper depth (time) to the left side of mannequin (p<.001) and showed better results in insufficient depth (time) and chest compression/recoil rate (p<.05). According to the quality of chest compression by control group, the right side of mannequin showed superior results in proper depth (time), insufficient depth (time), too left-centered compression position (time) and mean chest compression depth (mm) (p<.05) to the left side of mannequin. Conclusion : The group having practice from both right and left sides of mannequin was superior in the quality of chest compression to the group having practice from only right side of mannequin. How to practice cardiopulmonary resuscitation from both right and left sides of mannequin can be recommended and practice from left side of mannequin is also useful.
