Pulse Oximeter

The Descent™ watch has a wrist-based pulse oximeter to gauge the saturation of oxygen in your blood. Knowing your oxygen saturation can be valuable in understanding your overall health and help you determine how your body is adapting to altitude. Your watch gauges your blood oxygen level by shining light into the skin and checking how much light is absorbed. This is referred to as SpO2.

On the watch, your pulse oximeter readings appear as an SpO2 percentage. On your Garmin Connect™ account, you can view additional details about your pulse oximeter readings, including trends over multiple days (Setting the Pulse Oximeter Mode). For more information on pulse oximeter accuracy, go to garmin.com/ataccuracy.
