Pulse Oximeter
The Descent Mk2i device has a wrist-based pulse oximeter to gauge the peripheral saturation of oxygen in your
blood. 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 widget (Getting Pulse Oximeter
Readings, page 84). You can also turn on all-day readings (Turning On All-Day Pulse Oximeter Readings,
page 84). When you remain motionless, your device 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 device, 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.
