9. Evaluating measurement results
WARNING
The following table for evaluating your measurements does NOT apply to people with certain
pre-existing conditions (e.g. asthma, heart failure, respiratory diseases) or whilst staying at
altitudes above 1500 metres. If you have a pre-existing condition, always consult your doctor
to evaluate your measurements.
SpO₂ measurement
(oxygen saturation) in %
99-94
93-90
< 90
Decline in oxygen saturation depending on altitude
Note
The following table informs you of the effects of various altitudes on oxygen saturation value
and its impact on the human body. The following table does NOT apply to people with certain
pre-existing conditions (e.g. asthma, heart failure, respiratory diseases etc.). People with pre-
existing conditions can show signs of illness (e.g. hypoxia) at lower altitudes.
