How Can I Perform An Accurate Spo2 Measurement - Withings ScanWatch Series Installation And Operating Instructions Manual

What is a normal SpO2 level?
A SpO2 value is represented by a percentage. If your ScanWatch says 98%, this
means that each red blood cell is made up of 98% oxygenated and 2% non-
oxygenated hemoglobin.
Good blood oxygenation is necessary to supply the energy your muscles need in
order to function, which increases during a sports activity. If your SpO2 value is
regularly below 90%, this could be a sign of poor blood oxygenation, also called
hypoxemia.
SpO2 values generally vary between 90 and 100%:
• 95% to 100%: Normal.
90% to 94%: Below Average. This measurement detects that your blood
•
oxygen level is below average but still normal. The results can vary based on
a number of factors, including but not limited to your health profile (whether
you are a smoker, if you have asthma, if you are very athletic or not, if you
have tattoos, if you have known conditions such as hypotension, anemia, etc.),
your environment (altitude, temperature), the way the measurement is done
(standing/sitting position, wristband tightening, etc.). We suggest you check
for best practices and train to improve your gesture.
• Below 90%: Low. The value can be a possible sign of hypoxemia. The results
can vary based on a number of factors including your health profile, your
environment, and the way the measurement is done. We suggest you check
for best practices and repeat the measurement. In case results in this zone are
associated with symptoms, contact your doctor or a health professional who
will help you make a diagnosis and take preventive actions. Symptoms include
being short of breath after exertion, coughing, fast or slow heart rate, rapid
breathing, sweating.
Each SpO2 measurement can easily be found in the Health Mate app and can be
easily shared as a PDF.

How can I perform an accurate SpO2 measurement?

The result of a one-time measurement with ScanWatch depends on the
measurement conditions. Performing multiple measurements allows you to better
monitor SpO2 by creating a trend.
To make sure that the measured value is as close as possible to the real physical
value, or if the measurement is qualified as "inconclusive", make sure that your
watch is correctly positioned and tightened, and that your gesture follows these
best practices.
