Design and Development of an Automated CPR Machine Using Stepping Motor Technology

Abstract

Cardiopulmonary Resuscitation (CPR) is an essential emergency intervention aimed at preserving blood circulation and oxygenation during acute cardiac arrest. Manual CPR frequently faces obstacles including weariness, inconsistency, and diminished efficacy with time. This study gets around these problems by making an automated CPR device that uses stepping motor technology to give correct and consistent chest compressions that meet American Heart Association (AHA) standards. The suggested system has a stepping motor-driven compression mechanism, a Programmable Logic Controller (PLC) for managing operations, and a Human-Machine Interface (HMI) for monitoring in real time and letting the user interact with the system. The gadget offers customizable settings for compression depth and frequency, ensuring flexibility according to various patient requirements while complying with medical regulations. Performance assessments with CPR training manikins exhibited significant accuracy and reliability. According to AHA standards, the machine was accurate over 98% of the time when it came to compression frequency and 96% of the time when it came to compression depth. It also had an average peak compression force of 1063 N. Furthermore, the device's battery facilitates uninterrupted running for 1.5 hours, rendering it appropriate for extended emergency utilization. The study shows that the automated CPR device is a reliable, portable, and cost-effective alternative to manual CPR. It has big benefits for emergency medical care both before and after the hospital stay.
