Highlights In order to reduce the demand for oximeters, a Kolkata-based healthcare startup has come up with a mobile application called CarePlix Vital, which basically keeps a track of your blood oxygen level, pulse, and respiration rates. The app functions in a way that a user will be asked to place a finger on their smartphone’s rear camera and flashlight and within seconds, the oxygen saturation (SpO2), pulse and respiration rates are displayed on the device. CarePlix Vital uses artificial intelligence (AI) to determine the strength of finger placement. The second wave of COVID-19 has shattered the lives of people in India and this time the shortage of oxygen has forced people to buy oxymeters.
