pressure waveform.
The typical SpO2 waveform indicates not only a good waveform, but helps the user find a probe
placement with the least noise spikes present. The figure below represents an SpO2 waveform of
good quality.
If noise (artifact) is seen on the waveform because of poor probe placement, the photo detector
may not be flush with the tissue. Check that the probe is secured and the tissue sample is not too
thick. Pulse rate is determined from the SpO2 waveform which can be disrupted by a cough or
other hemodynamic pressure disturbances. Motion at the probe site is indicated by noise spikes in
the normal waveform. (See the figure below.) It has been noted that letting the patient view the
SpO2 waveform enables them to assist in reducing motion artifact.
Stability of SpO2 Values
The stability of the displayed SpO2 values can also be used as an indication of signal validity.
Messages are provided in the SpO2 values window to aid you in successful SpO2 monitoring.
