Viewing Your SpO2 Readings in Flight
The SpO2 readings are intended for backup information only. Always defer to applicable flight instruments for primary awareness.
The D2™ Air X10 watch 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. During a flight, the watch automatically takes pulse oximeter readings more frequently, so you can monitor your SpO2 percentage.
TIP:
You can improve the accuracy of your SpO2 readings by turning on all-day acclimation mode in the pulse oximeter glance settings (Changing the Pulse Oximeter Tracking Mode).
