7 Assessing the Validity of a
SpO Reading

You can check the quality of the pleth wave
and the stability of the SpO values to assess
2
whether the sensor functions properly and
whether the SpO readings are valid. Always
2
use these two indications simultaneously to
assess the validity of a SpO reading.
2
Generally, the quality of the SpO pleth
2
wave reflects the quality of the light signals
obtained by the sensor. A wave of poor
quality manifests a decline of the signal
validity. On the other hand, the stability of
the SpO values also reflects the signal
2
quality. Different from varying SpO
2
readings caused by physiological factors,
