Q: Why is the Blood Oxygen Measurement lack 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 a finger-width 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.
