Learning Cardiopulmonary Resuscitation in the School Setting: RCP-KNOW Project.

Title: Out-of-hospital cardiorespiratory arrest and learning cardiopulmonary resuscitation in the school setting: evidence synthesis. CPR-KNOW PROYECT.

Background: The high incidence, associated morbidity and mortality, and the great individual, social and economic impact of out-of-hospital cardiorespiratory arrest (OHCA) make it a priority for all health systems worldwide. To increase the rates of potential first responders who act appropriately, applying basic life support (BLS) measures in the OHCA, the European Resuscitation Council includes among its latest recommendations the training of all school children through the "Kids Save Lives" initiative.

Objectives: to determine, through a randomized clinical trial, the effectiveness of two training strategies for increasing theoretical and practical knowledge of BLS in schoolchildren and adolescents.

Methodology: To evaluate the effectiveness of two (Cardiopulmonary Resuscitation) CPR teaching interventions in improving the following outcome variables: theoretical knowledge and practical skills, CPR quality; as well as its relationship with the anthropometric, sociodemographic and physical condition variables of the schoolers.

* Intervention group 1 (IG1): a 2-hour theoretical-practical session on the BLS sequence taught by a Nursing professional performing the practice with a mannequin. Instructor/school ratio: 1/25 for the theoretical session and a school/mannequin ratio: 2-3/1. * Intervention group 2 (IG2): a session with short video (approximately 5-10 min) and other teaching resources (puzzle), without practice on a mannequin. Video/school ratio: 1/25 and a school/teaching resource (puzzle) ratio: 1/1.
