Design of Microcontroller-Based Cardiopulmonary Resuscitation (CPR) Practice Tool

Abstract

Cardiac arrest is the leading cause of death in cardiovascular emergencies, both in prehospital and intrahospital events. This case is called out-of-hospital cardiac arrest (OHCA). Quality Cardiopulmonary Resuscitation (CPR) can optimize the return of spontaneous circulation in OHCA. However, many people are not confident in carrying out this procedure, so they need CPR training to respond quickly, responsively, and accurately in assisting OHCA victims. In this study, we will make a tool that resembles the torso and human head and monitor and calculate the parameters that are a factor in the success of the CPR process. The system consists of the compression process, airways process, and breathing process. A microcontroller-based CPR practice tool can function exactly with the CPR process in humans. The designed system can simulate the CPR process by measuring every parameter of CPR, namely compression 30 times in 15–18 seconds with the optimal pressure is ±50kg, 30° angle slope for airways, and two times in 5 seconds for breathing. The design of this tool will provide a more economical solution, making it easier for a relevant public organization to accommodate the tools needed to carry out CPR training so that more people can provide CPR assistance.
