Cardiovascular diseases are the leading cause of worldwide morbidity and mortality in the adult population, and Cardiopulmonary Resuscitation (CPR) is the typical outcome. Meanwhile, airway obstruction and respiratory diseases prevail in children. Recent studies reveal the importance of training laypeople in Basic Life Support (BLS), but the low economic viability of practical education is notorious, especially in developing countries like Brazil. Thus, a low-cost teaching strategy is necessary. This article aims to demonstrate an intervention strategy in the community for theoretical and practical teaching of BLS, considering social demands, methodology, and expectations of the REVIVA extension project, UFJF. This project aims to train laypeople in clearing the airways and cardiopulmonary resuscitation in Juiz de Fora (Brazil), using mannequins built with reused materials.
