SpO2 Monitoring: Signal and Data Validity
Signal and Data Validity
It is extremely important to determine that the probe is attached to the
patient correctly and the data is verifiable. To make this determination,
the signal strength indicators on the Apex Oximeter and the CIC Pro are
of assistance.
Signal Strength Indicator
A signal strength (perfusion) indicator is displayed on the Apex Oximeter
display and at the CIC Pro in the appropriate patient window.
On the Apex Oximeter, this indicator is a perfusion LED that blinks with
each SpO2 pulse detected. The LED blinks green for each acceptable
strength pulse. It blinks yellow for SpO2 signals of marginal quality, and
blinks red when the SpO2 signal is too weak or the quality is very poor.
When the perfusion LED blinks red, the numeric data displayed on the
Apex Oximeter will be replaced by dashes within 10 seconds.
At the CIC Pro, the signal strength indicator consists of 0, 1, 2, or 3
(strongest) asterisks, depending on the strength of the signal.
Proper environmental conditions and probe attachment help ensure a
strong signal.
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.
