Importance of Using Proper Techniques to Teach Cardiopulmonary Resuscitation to Laymen

Abstract

Immediate attempts to resuscitate patients with cardiac arrest by lay bystanders distinctly increase the chances of survival in such patients. In the present study we investigated possibilities of intensifying the cardiopulmonary resuscitation (CPR) training of laymen. A group of 46 young conscripts (test group) was given 2 hours of CPR instruction in what was considered the most efficient way. The procedures included showing a film on the theory and practice of CPR, a discussion of the film, and then 3 to 5 min instructed individual practice with a recording manikin. Another 56 conscripts participated in a I-h illustrated lecture on CPR, which was followed by group training with a non-recording manikin; they served as a reference group. The performance of the subjects in CPR was measured with a recording manikin before and 2 months after the training. Before training, none of the subjects passed the surprise resuscitation test. After training, the skills of 62% of the subjects in the test group were acceptable according to original criteria for lay public, and 28% passed the test according to the strict criteria for medical personnel. The less intensive training given to the reference group did not improve the acceptability of resuscitation. It is concluded that CPR training for laymen may lead to failure to attain an adequate level of skill. Proper training techniques and equipment are important, but even their use does not guarantee that an adequate level of CPR performance will be attained by all laymen if their skills are not later refreshed.
