Question about Garmin vivosmart 4
Hello, is it possible to measure the oxygen saturation at night?
Helpful answer
Yes - the device measures the blood oxygen level. As the device measures blood oxygen in the small (peripheral) vessels of the skin, this is called peripheral oxygen saturation (SpO2). To activate/adjust: Device Settings > Fitness Tracker > Pulse Oximeter. Important: Not intended for medical use!
Have fun!
