Pulse Oximeter

WARNING

The Garmin device, accessories, heart rate monitor, pulse oximeter sensor, and related data are intended to be used only for recreational purposes and not for medical purposes, and are not intended to diagnose, monitor, treat, cure, or prevent any disease or condition.

The vívoactive device has a wrist-based pulse oximeter to gauge the saturation of oxygen in your blood. Knowing your oxygen saturation can help you determine how your body is adapting to exercise and stress. Your device 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 device, 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 (Changing the Pulse Oximeter Tracking Mode).
