Background Cardiorespiratory Arrest (CRP) is a medical emergency that requires urgent aid as well as technical skills to initiate Cardiopulmonary Resuscitation (CPR) maneuvers, primarily among the lay population, seeing as the majority of CRP episodes take place in community environments. Purpose: The purpose of this study is to compare the Basic Life Support (BLS) skills of high school students before and after a theoretical-practical approach. Method: A quasi-experimental study was conducted, consisting of theoretical-practical training on BLS running 60 minutes total (20 minutes of theory and 40 minutes of practice), addressing various steps in layman’s out-of-hospital BLS. Evaluations were conducted before and after training. The instrument was developed by the researchers themselves and underwent a previous validation process. The statistical software employed for the purpose of analyzing the data was SPSS version 21.0 for Windows. At the outset, descriptive statistics were employed to present the data, as well as the Wilcoxon test to compare the results of questionnaires taken before and after the intervention. Results: The sample consisted of 322 students from private institutions in Belo Horizonte, Brazil. The median age was 16.0 years, with an interquartile interval (IQ) of 2 years, with 181 (56.2%) students being female and 141 (43.8%) male. The before and after results revealed statistically significant differences in performance: pre-training – median = 5 points, IQ = 2 points; post training – 9 points, IQ = 2 points; p < 0.0001. Conclusion: The conduction of theoretical-practical classes was followed by an increase in correct answers to the BLS questionnaire. The results suggest that simple educational strategies might aid in the training of lay young people to respond correctly to CRP scenarios.
