Status Messages: Possible Causes: Corrective Actions:
Data unavailable due
to poor signal quality
[0028]
The signal quality is too low
to accurately calculate a BIS
value. The BIS value and
other trend variables that
are adversely affected by
artifact are not displayed
1.
Artifact, such as those
generated by motion or
eye blinks, is causing
loss of EEG
recognition.
2. EMG Bar indicates
electrical activity that
may be interfering with
EEG recognition.
3. PIC is defective.
4. BISx is defective.
Note : This message may
occur as a result of artifact
(non-EEG signal) such as
those generated from
motion (patient movement
or eye blinks) or the
presence of electro-cautery,
warming blankets, or other
devices.
1. If ARTIFACT label
appears above the EEG
waveform box, attempt to
identify and eliminate
artifact source.
2. If EMG bar is illuminated,
attempt to determine and
eliminate cause.
3. Verify Sensor Check
passes. If not, replace PIC.
4. Replace BISx Bulkhead
Connector or replace BISx.
BIS Out of Target
Range
Low [0029]
High [0030]
The BIS has fallen outside
the target range set by the
user.
1. Check patient.
2. Take note of BIS at limit
set by user.
