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. (Refer to this chapter, Troubleshooting.)
WARNING
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.
