An oximeter, which tests the amount of oxygen in the blood, is one of the most important tools for checking the condition of positive patients (Spo2). A COVID-19 positive patient must typically maintain a SpO2 level above 95%, and anything below that necessitates immediate medical attention.
Meanwhile, CareNow Healthcare, a health-tech startup based in Kolkata, has developed CarePlix Vitals, a smartphone app that allows users to monitor vitals such as pulse rate and SpO2 by placing the index finger on the phone’s rear flashlight.
The app claims to use the same principles as photoplethysmography (PPG), which uses a light source to detect volumetric variations in blood circulation. In this case, the app employs the phone’s flashlight rather than the infrared light found in an oximeter.
Users must sign up using their email address. According to the Apple App Store privacy chart, the app collects users’ contact information as well as usage data. Users can save scans from each test and use ‘vitals analytics’ later.
Subhabrata Paul, co-founder of CareNow Healthcare, told The Indian Express that the app “was 96 percent accurate with heart beats and 98 percent accurate in case of oxygen saturation” during trials with 1200 people.
Overall, the app can be useful for users who are unable to obtain an oximeter due to its scarcity or the instrument’s rising cost during the COVID-19 pandemic.
The CarePlix Vitals app is currently free to download from Google Play and the Apple App Store.
