Background The use of realistic simulation methodology is used in several learning scenarios, allowing students to participate directly in the problematization of situations that require immediate professional action. Objective Develop, enable and validate a low-cost simulator for cardiopulmonary resuscitation procedures in infants. Methods An experimental study with undergraduate students of the 1st year of the Nursing course at a higher education institution in the State of Paraíba, Brazil, developed a simulator model with dimensions similar to an infant with low cost materials and enabled the use as a prototype for training Basic Life Support. The prototype was developed with the accessories for stop chocking and cardiopulmonary resuscitation maneuvers. The data collection instrument was a questionnaire based on the American Hearth Association Basic Life Support guideline to enable and validate the Basic Life Support training instrument. Results The low-cost prototype for Basic Life Support training was used as an appropriate learning object and enabled the teaching-learning process as a low-cost resource accessible. Based on the questionnaire applied, we observed that there was an increase in the median number of correct answers and a reduction in the median of errors, which indicated an improvement in the acquisition of information and improvement in learning, observed through the Signal Sampling of Related Samples and the Wilcoxon Signal Test of hits (M A ) and errors (M E ), before and after training where it was found that there was an increase in M A and a reduction in M E with 5% significance (p <0.001). The frequencies of response modifications after training with the simulator were also studied by means of the two-tailed McNemar test where Q 1 , Q 2 , Q 3 , Q 4 , Q 8 , Q 9 , Q 13 and Q 15 questions showed significant changes (p <0, 05). Conclusion It was developed a prototype that obtained its application in simulation of training activity in Basic Life Support, which made possible the accomplishment of the procedures in the proper way in positioning and simulation of cardiac resuscitation, mouth / nose ventilation and tapping in the scapular region, which allowed to validate stop chocking and resuscitation training as a low-cost alternative to health education.
