Introduction: Training for cardiopulmonary resuscitation is a very important topic for society, trainers and researchers. However it is not yet established who should be trained and by whom nor how the training programmes should be accomplished. We developed a study to evaluate an existing programme where medical students train high school students in cardiopulmonary resuscitation using instrumented mannequins to teach and collect performance data.
Method: The students of four randomly selected high school classes were trained by four randomly selected medical students and were evaluated by an independent evaluator. The level of knowledge provided and the level of technical skills acquired were analysed.
Results: One hour of lecturing was enough to increase the mean of correct answers from 39.52% to 78.48% when we tested knowledge. Testing for skills retention we found that that 92.75% of trained students taped the shoulder; 95.65% asked loudly “Are you all right?” at the right moment; 97.1% shouted for help at the right moment, the entire group remembered to check the breathing at the right moment, and 92.75% executed a correct head tilt chin lift manoeuvre; 86.9% remembered to call 112 at the right moment. Automatic recordings showed that mean flow fraction was 80.74%, mean no flow time was 18.9 seconds, mean frequency of chest compressions was 134.7/min and mean compression depth was 39.06 mm.
Conclusions: The results showed that high school students achieved a good level of knowledge and acceptable cardiopulmonary resuscitation skills when trained by medical students.
