Effect of an Educational Intervention on CPR Knowledge and Skills in Schoolchildren

This study aims to evaluate the effectiveness of a CPR intervention for children aged 7 and 8. Given the high prevalence of out-of-hospital cardiac arrests (OHCA) and the proven benefits of early CPR training, the study seeks to determine whether a structured intervention can improve young children's knowledge and skills in basic life support. What is the effect of a CPR training intervention on the knowledge and skills of 7- and 8-year-old schoolchildren? Cardiac arrest is a leading cause of mortality worldwide. Research shows that survival rates increase significantly when CPR is performed promptly by a trained bystander. Countries with early CPR training programs in schools, such as Norway and Denmark, report better survival outcomes. However, in Latin America, CPR education in schools is still in its early stages. Evidence suggests that children can effectively learn and retain CPR knowledge, and they can serve as multipliers by passing their knowledge to family and peers. Study Design: This is a non-randomized, double-blind controlled trial with four phases:
