The situation and training effectiveness of hands only cardiopulmonary resuscitation in middle school students

Abstract

Objective To investigate the situation of hands only cardiopulmonary resuscitation(CPR) and training effectiveness of CPR in middle school students. Methods By the principle of random stratified cluster sampling, 7 687 middle school students in Changsha city were trained on hands only CPR through the scene theory teaching and anthropomorphic dummy in this study.The training content included who was rescued by CPR, when patients require CPR, how long can cause irreversible brain damage, the standardized process of CPR, the position of CPR, the depth of CPR, and the ratios of breath-to-compression.We analyzed the middle school students′ awareness of hands only CPR knowledge before and after the training, investigated the middle school students′ willingness and way to accept knowledge of first aid. Results All of 7 687 middle school students in Changsha city received questionnaire survey and trained on hands only CPR, including 3 778(49.15%) boys and 3 909 girls(50.48%). The knowledge of hands only CPR was mainly derived from the book, television, network, and education from schools.Before training, the awareness rates of the knowledge on who was rescued by CPR and the position of CPR were more than 50%, and the awareness rates on the rest of knowledge were less than 50%.The awareness rates on hands only CPR were more than 75% by training, which were significantly increased compared with those before training(P<0.01). Conclusion The knowledge on hands only CPR is very scarce in middle school students in Changsha city, and the awareness on hands only CPR can be significantly improved by the scene theory teaching and anthropomorphic dummy.
