Rev. 1.4 5.SpO2
Stability of SPO2 Values
The stability of the displayed SPO2 values can also be used as an indication of signal validity.
Although stability is a relative term, with a small amount of practice one can get a good feeling for
changes that are artifactual or physiological and the speed of each. Messages are provided in the
SPO2 values window to aid you in successful SPO2 monitoring.
In the monitoring of patients the coincidence of adverse conditions may lead to a disturbed
signal going unnoticed. In this situation artifacts are capable of simulating a plausible parameter
reading, so that the monitor fails to sound an alarm. In order to ensure reliable patient
monitoring, the proper application of the probe and the signal quality must be checked at
regular intervals.
