During a semi-experimental study, 12068 ninth-grade high school students entered the study. Course content included BLS and airway maneuvers regarding foreign body aspiration. Students' level of knowledge and performance was assessed based on a questionnaire. The mean level of knowledge of students before training was 3(3-2) and after training was 5(4-5). Approximately 60% of students had excellent scores on practical activities. We conclude that resuscitation training can be effective in promoting public health.
