The O2Ring is designed to accurately measure oxygen saturation (SpO2%) and heart rate data during use. It can be worn on any finger and allows data recording without the need for a bulky sensor covering the fingertip, unlike traditional oximeters.
The O2Ring records blood oxygen, heart rate, and body movement data every 4 seconds. Data is stored in the O2Ring's internal memory for later transfer to the ViHealth app. Data can be shared as a picture, PDF, or raw data (CSV) for viewing in spreadsheet software.
