Let’s pulse device assist in cardiopulmonary resuscitation by professionals and laypersons

Abstract

It is a study whose objective is to describe the electronic circuit project of a stimulus generator device for the execution of chest compressions at the appropriate frequency for cardiopulmonary resuscitation (CPR). The electronic system was designed using a Microchip PIC family microcontroller with programming in the “C” language with connection of the main components and their respective functions and programming. Thus, Let’s pulse consists of a dedicated embedded system accommodated in the form of a bracelet or wristband so that the rescuer can receive stimuli satisfactorily without compromising the execution of CPR. Unlike other devices, it offers real-time luminous, vibratory, sound and musical stimuli. The device has the potential to efficiently assist in maintaining the appropriate frequency of chest compressions during CPR and in training and qualifying rescuers. It is believed that the development of Let’s pulse will contribute significantly to the Unified Health System in increasing the quality of CPR and consequently reducing premature death from cardiac arrest.
