 Blood Oxygen Level Measurement Accuracy
The Blood oxygen level will be affected by factors such as motion, watch placement on
the wrist, skin temperature and skin perfusion. These factors will cause fluctuations in
blood oxygen measurements.
For a single measurement on the watch, please wear the watch two fingers wide below
the wrist bone, snug but comfortable on your wrist. When measuring, stay still and make
sure your wrist is flat with the watch facing up. If you are sitting, you can rest your arm on
a table with the watch facing up. For sleep blood oxygen detection, please wear the watch
snugly but comfortable on the wrist when sleeping.
The smart watch blood oxygen sensor isn't a medical device and won't be able to
diagnose or monitor any medical conditions. If there is a problem with the
measurement, we recommend you consult your doctor.
