Viewing Your SpO2 Readings in Flight
CAUTION
The SpO2 readings are intended for backup information only. Always defer to applicable flight instruments for
primary awareness.
The D2 Air 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. During a flight, the device 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 widget settings (
Changing the Pulse Oximeter Tracking Mode, page 24
).
1 Start a FLY activity.
2 Swipe up or down to scroll through the data screens.
Your most recent reading appears as an oxygen saturation percentage.
NOTE: If you are too active for the device to determine your oxygen saturation, dashes appear instead of a
percentage. You should remain stationary for up to 30 seconds while the device reads your blood oxygen
saturation.
