Getting Pulse Oximeter Readings

You can manually begin a pulse oximeter reading by viewing the pulse oximeter widget. The accuracy of the pulse oximeter reading can vary based on your blood flow, the device placement on your wrist, and your stillness.

NOTE: You may need to add the pulse oximeter widget to the widget loop.

1. While you are sitting or inactive, swipe up to view the pulse oximeter widget.
2. Tap the widget to view more details and begin a pulse oximeter reading.
3. Hold the arm wearing the device at heart level while the device reads your blood oxygen saturation.
4. Keep still.

   The device displays your oxygen saturation as a percentage, and a graph of your pulse oximeter readings and heart rate values for the last four hours.
