Getting Pulse Oximeter Readings

The elevation scale.

A graph of your average oxygen saturation readings for the last 24 hours.

Your most recent oxygen saturation reading.

The oxygen saturation percentage scale.

A graph of your elevation readings for the last 24 hours.

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

  1. While you are sitting or inactive, press DOWN to view the pulse oximeter glance.
  2. Wait until the watch 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 watch at heart level while the watch reads your blood oxygen saturation.
