A Simple User-friendly Android Application for Oxygen and Blood Pressure Measurement

In the current generation, health is a major concern for people regardless of age. People were so drastically affected by the pandemic that they couldn’t muster up the courage to visit a hospital for a general checkup. Monitoring one’s health condition is vital, especially for senior citizens. Photo-plethysmography is an optical measurement method used to compute the arterial blood volumetric variations of blood circulation with the help of a pulse oximeter. A pulse oximeter uses a bright LED at one end and a detector on the other end to measure the pulse rate and oxygen saturation. Hypoxemia is one of the common issues faced in recent times which is caused by the dropping of oxygen levels. It causes frequent headaches, dysfunction of the brain, heart, etc. Hence, there exists a necessity for a device that can monitor a person’s oxygen levels and provide a rough estimate. This paper proposes an android application that can provide an estimate of a person’s oxygen levels with over 90% accuracy. The application also predicts the rough value of blood pressure.
