Affordable Real-Time Heart Rate, ECG & SpO2 Monitoring System Using Internet of Things (IoT)

Abstract

Abstract: The healthcare industry now has an incomparable platform thanks to the Internet of Things technology, making it possible to quickly and effectively deal with challenges concerning healthcare. There has been a steady rise in the number of deaths due to sudden cardiac arrest (SCA) cases in developing countries and a lack of widespread use of an AED in these countries. The purpose of this study is to create an affordable Automated External Defibrillator (AED) that can be connected to IoT and can overcome certain drawbacks of the current AEDs. In the first phase of implementation, we attempt to create a Heart Monitoring System that can read Beats Per Minute (BPM), Electrocardiogram (ECG), and Saturation of Peripheral Oxygen (SpO2) using off-the-shelf sensors and display the data on a smartphone app. These sensors are connected to a Raspberry Pi 3b+, a single-board computer (SBC), which controls the entire system. The implementation of the system is successful, transmitting heart vitals to a smartphone app in real time. Further, the limitations of the system and future improvements are also discussed. The study builds a Heart Monitoring System under $67 with a few drawbacks. Further studies with better equipment are required to make the system accessible and less error-prone.
