Getting Pulse Oximeter Readings
You can manually begin a pulse oximeter reading on your device at any time. The accuracy of the reading can
vary based on your blood flow, the device placement on your wrist, and your stillness.
1 Wear the device above your wrist bone.
The device should be snug but comfortable.
2 Select UP or DOWN to view the pulse oximeter widget.
3 Select START.
4 Hold the arm wearing the device at heart level while the device reads your blood oxygen saturation.
5 Keep still.
The device displays your oxygen saturation as a percentage.
NOTE: You can customize the pulse oximeter settings in your Garmin Connect account.
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 widget, hold UP.
2 Select Sleep Pulse Ox > On.
