SpO2 Alarm: A Tool for Health Care

Abstract

The continuous measurement of the level of oxygen concentration in blood (SpO2) and the heart rate (HR) may help verify the state of health of the cardiovascular system. SpO2 Alarm is a wearable technological tool that consist of a SpO2 and HR measurement device and a mobile-device application that collects, via Bluetooth, the information obtained from the MAX30102 module once processed through the ATMega328P microcontroller (included in the Arduino Nano board), and allows real-time visualization of both parameters. The SpO2 Alarm was intended to be used by patients with a risk of suffering low levels of SpO2, which then sends an alert with the exact location of the user to a designated contact in case of detecting a low concentration of oxygen in blood. The goal of the SpO2 Alarm is to facilitate the detection and timely medical attention of cardiovascular diseases and emergencies.
