Is there any difference in cardiopulmonary resuscitation performance according to different instructional models of cardiopulmonary resuscitation education for junior and senior high school students?

Abstract

Objective: This study aims to determine whether or not cardiopulmonary resuscitation (CPR) skills differ according to different instructional models for CPR education and training for junior and senior high school students. Methods: This was a prospective and randomised study including 519 junior and senior high school students. After the lecture on CPR, students practiced the skill on the manikin. Group 1 used model 1 and Group 2 used model 2 for practical training and practical skills and CPR performance quality were evaluated. Results: Data from skill tests were analysed in 229 students in group 1 and 210 students in group 2. The total score of sequence skill tests was 17.8 +/- 2.0 points. During 2 cycles, no chest elevation was observed in 33.3% and was significantly lower in group 1. There were no significant differences in the frequency of proper ventilation and in ventilation volume between the 2 groups. Excessive ventilation was more frequently observed in group 1 and insufficient ventilation was observed more frequently in group 2. The percentage of the frequency of a proper chest compression rate was 80.5 +/- 31.2% and there were no significant differences in proper and insufficient depths, mean rate and recoil of the chest in chest compression between the 2 groups. Conclusions: There were differences in CPR skills according to different CPR training manikins. Therefore, certain conditions seem to be considered in selection of instructional models for CPR psychomotor skills. (Hong Kong j.emerg.med. 2011;18:375-382)
