Prototype of a Portable Cardiopulmonary Resuscitation Device Using Microcontroller Technology

Abstract

The objective of this study is to design and develop a portable cardiopulmonary resuscitation (CPR) device utilizing the Arduino Uno Atmega 328 microcontroller. The primary aim is to provide immediate first aid to individuals experiencing sudden cardiac arrest, thereby reducing the risk of mortality caused by delays in emergency response. The device is constructed using the Arduino Uno Atmega 328 microcontroller as its core component, integrated with a DC motor to facilitate the compression mechanism. It is further equipped with a pulse heart sensor to monitor the patient's pulse rate, which is displayed on a 16x2 LCD screen. This research adopts the Research and Development (R&D) methodology. The system is designed to be user-friendly and highly portable, ensuring practicality in emergency situations. The findings indicate that the device is capable of delivering chest compressions at a consistent rate of 80 compressions per minute. Moreover, the pulse detection feature demonstrates a high level of accuracy, with an error margin of only 1.29% when compared to a standard oximeter. These results highlight the potential of the device as an effective tool for emergency cardiac care.
