Viewing Your SpO2 Readings in Flight
The D2™ Delta PX device has a wrist-based pulse oximeter to gauge the saturation of oxygen in your blood (SpO2). During a flight, the device automatically takes pulse oximeter readings more frequently, so you can monitor your SpO2 percentage.
During a flight, scroll up or down to view the SpO2 data screen.

Your most recent reading appears as an oxygen saturation percentage and position on the color gauge.

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.
