Pulse Oximeter

The D2™ Delta PX device has a wrist-based pulse oximeter to gauge the saturation of oxygen in your blood (SpO2). Knowing your oxygen saturation can help you determine how your body is adjusting to high altitudes. As your altitude increases, the level of oxygen in your blood can decrease. When you view the pulse oximeter widget while you are not moving, 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. During a flight, the device automatically takes pulse oximeter readings more frequently, so you can monitor your SpO2 percentage (Viewing Your SpO2 Readings in Flight).

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.
