Getting Pulse Oximeter Readings

You can manually begin a pulse oximeter reading by viewing the pulse oximeter widget. The widget displays your most recent blood oxygen saturation percentage.

1. While you are sitting or inactive, press UP or DOWN to view the pulse oximeter widget.
2. Wait until the device begins the pulse oximeter reading.
3. Remain motionless for up to 30 seconds.

NOTE: If you are too active for the watch to get a pulse oximeter reading, a message appears instead of a percentage. You can check again after several minutes of inactivity. For best results, hold the arm wearing the device at heart level while the device reads your blood oxygen saturation.
