Medical students teaching cardiopulmonary resuscitation to middle school Brazilian students.

[Article in English, Portuguese]



Diseases of the circulatory system are the most common cause of death in Brazil. Because the general population is often the first to identify problems related to the circulatory system, it is important that they are trained. However, training is challenging owing to the number of persons to be trained and the maintenance of training.


To assess the delivery of a medical-student led cardiopulmonary resuscitation (CPR) training program and to assess prior knowledge of CPR as well as immediate and delayed retention of CPR training among middle school students.


Two public and two private schools were selected. CPR training consisted of a video class followed by practice on manikins that was supervised by medical students. Multiple choice questionnaires were provided before, immediately after, and at 6 months after CPR training. The questions were related to general knowledge, the sequence of procedures, and the method to administer each component (ventilation, chest compression, and automated external defibrillation). The instructors met in a focus group after the sessions to identify the potential problems faced.


In total, 147 students completed the 6-month follow-up. The public school students had a lower prior knowledge, but this difference disappeared immediately after training. After the 6-month follow-up period, these public school students demonstrated lower retention. The main problem faced was teaching mouth-to-mouth resuscitation.


The method used by medical students to teach middle school students was based on the see-and-practice technique. This method was effective in achieving both immediate and late retention of acquired knowledge. The greater retention of knowledge among private school students may reflect cultural factors.
