BIS: Check SQI Level EMG Bar indicates electrical activity that
may be interfering with EEG recognition.
If EMG bar is illuminated,
attempt to determine and
eliminate cause.
Defective PIC. Verify Sensor Check passes. If
not, replace PIC.
Defective BISx. Replace the BISx.
NOTE: This message is displayed when
the Signal Quality is less than half of the
level desirable for optimal monitoring
conditions or when the signal quality is
too low to accurately calculate a BIS
value. This may occur as the result of
artifact (non-EEG signal) such as that
generated from motion (patient
movement or eye blinks) or the presence
of electrocautery, warming blankets, or
other devices.
BIS: Invalid Sensor Poor or contaminated connection
between sensor and PIC.
Connect/clean connection
between sensor and PIC.
Defective sensor. Replace the sensor.
Defective PIC. Replace the PIC.
Defective BISx. Replace the BISx.
BIS: Noise The signal from the electrode goes
beyond the measurable range
Re-prep the electrodes and
check all connections.
