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. NOTE: The first time you view the pulse oximeter glance, the watch must acquire satellite signals to determine your elevation. You should go outside, and wait while the watch locates satellites. 1 While you are sitting or inactive, press UP or DOWN to view the pulse oximeter glance. 2 Press START to view glance details. 3 Press START, and select Take Reading to begin a pulse oximeter reading. 4 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. Turning On Pulse Oximeter Sleep Tracking You can set your device to continuously measure your blood oxygen saturation while you sleep. NOTE: Unusual sleep positions can cause abnormally low sleep-time SpO2 readings. 1 From the pulse oximeter glance, hold . 2 Select Pulse Ox Options > During Sleep.
