This mobile application leverages the photoplethysmography (PPG) principle, using a smartphone’s camera and flash to estimate blood oxygen saturation (SpO2) and pulse rate. The user typically places a fingertip over the camera lens, and the app analyzes the light absorbed and reflected by the blood to provide these readings. The application’s functionality mirrors that of traditional fingertip devices, albeit relying on the smartphone’s built-in sensors.
Monitoring physiological parameters such as SpO2 and pulse rate offers potential benefits for individuals managing respiratory conditions, athletes tracking performance, and those seeking general wellness insights. Historical context shows that non-invasive monitoring of oxygen saturation has evolved significantly, from bulky clinical devices to more accessible smartphone-based solutions. This accessibility allows for more frequent personal monitoring, potentially identifying trends and anomalies for discussion with healthcare professionals.
