Viewing Your SpO2 Readings in Flight

WARNING

The SpO2 readings are intended for supplemental information only. Always defer to applicable flight instruments for primary awareness.

The watch has a wrist-based pulse oximeter to gauge the saturation of oxygen in your blood (SpO2). 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 the All Day pulse oximeter mode (Setting the Pulse Oximeter Mode).
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 watch to determine your oxygen saturation, dashes appear instead of a percentage. You should remain stationary for up to 30 seconds while the watch reads your blood oxygen saturation.
