Cardiopulmonary resuscitation (CPR) is an emergency procedure primarily applied to victims of sudden cardiac arrest. Due to its importance in preserving circulatory and brain functions, it is essential to promote training in the development of CPR techniques, as well as to implement improvements in training models. This work aims to develop a CPR simulator with a sensor module to evaluate chest compression parameters. The proposed model incorporates an ultrasonic sensor to regulate compression frequency and a mobile application that displays key study variables: number of compressions, effective compressions, compression depth, and compression cycles. The system was specifically designed for 10th level medical students, providing them with real-time feedback on their performance. The design favored the acquisition of skills by the students, and the quality of CPR was significantly better compared to conventional training models. Therefore, the implementation of the system had a meaningful impact on the students’ learning curve, making it a promising tool for medical education.
