Monitoring Bispectral Index (BIS)
2000966-386D
Dash™ 3000/4000/5000
18-7
SR
The suppression ratio value identifies the percentage of epochs in the last 63 seconds
in which the EEG signal is considered suppressed, or the percentage of time the EEG
waveform is flat-line over the previous minute. The range is zero to 100 percent.
SQI
The signal quality index value identifies the percentage of good epochs (episodes) in
the last 60 seconds that could be used to calculate the bispectral index. The optimum
SQI is 100.
SEF
The spectral edge frequency is the frequency between zero and 30 Hz at which 95
percent of the total power is a lower frequency and five percent exceeds the spectral
edge frequency.
EMG
The electromyograph value measures the absolute power in the 70 to 110 Hz range.
The power value is in dB (decibels). This is the measurement of the facial muscle
activity or other artifact in the EEG signal within this frequency range.
The indicator displays up to seven bars; the more bars the greater the EMG activity.
No bars display when EMG values are less than 30 dB. Seven bars display when the
EMG values are 55 dB.
Troubleshooting
For clinical-level troubleshooting, refer to the GE “Critical Care Monitoring Clinical
Reference and Troubleshooting Guide.”
Message
Cause
Solution
CHECK SENSOR - RESET BIS
Sensor failure.
Reposition or replace the sensor, PIC cable
or BISx.
CHECK BIS - RESET BIS
Hardware failure.
Reconnect BISx.
COMM ERROR
Communication failure.
Reinstall BISx.
CONNECT SENSOR
Connection or communication failure.
Reposition or replace the sensor, PIC cable
or BISx.
BIS FAILURE
Over-current electrical condition.
Contact service.
BIS TEST IN PROGRESS
A self test is in progress.
This is a normal procedure message.
EXPIRED SENSOR
The current time and date exceeds the
recommended usage date of the sensor.
Select
Resume BIS
to initiate a sensor
check. If the sensor check passes, BIS
monitoring will begin. Then Re-prep or
replace the sensor, PIC cable or BISx.
