Getting Pulse Oximeter Readings
You can manually begin a pulse oximeter reading by viewing the pulse oximeter glance. The glance displays your most recent blood oxygen saturation percentage, a graph of your hourly average readings for the last 24 hours, and a graph of your elevation for the last 24 hours.
- While you are sitting or inactive, press UP or DOWN to view the pulse oximeter glance.
- Press START to view glance details and begin a pulse oximeter reading.
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.
- Press DOWN to view a graph of your pulse oximeter readings for the last seven days.
