Garmin DESCENT MK3 Series User Manual

Pulse Oximeter
Your watch has a wrist-based pulse oximeter to gauge the peripheral saturation of oxygen in your blood (SpO2).
As your altitude increases, the level of oxygen in your blood can decrease. Knowing your oxygen saturation can
help you determine how your body is acclimating to high altitudes for alpine sport and expedition.
You can manually begin a pulse oximeter reading by viewing the pulse oximeter glance (Getting Pulse Oximeter
Readings, page115). You can also turn on all-day readings (Setting the Pulse Oximeter Mode, page115). When
you view the pulse oximeter glance while you are not moving, your watch analyzes your oxygen saturation and
your elevation. The elevation profile helps indicate how your pulse oximeter readings are changing, relative to
your to elevation.
On the watch, your pulse oximeter reading appears as an oxygen saturation percentage and color on the graph.
On your Garmin Connect account, you can view additional details about your pulse oximeter readings, including
trends over multiple days.
