The BIS parameter field contains the following
elements:
A Bispectral index label (BIS)
B Secondary parameter label (selectable)
C Secondary parameter value
D EMG label
E Electromygraph bargraph indicating the current
amplitude of the EMG signal
F Signal quality index (SQI) bargraph indicating
the quality of the detected signal
G Signal quality index label (SQI)
H BIS value
EMG bar graph
The EMG bar graph consists of 5 tic marks. As the
amplitude increases, more tic marks are filled in
white.
A First section is filled in – 30 to 38 dB
B Second section is filled in – 39 to 47 dB
C Third section is filled in – 48 to 55 dB
D All sections filled in – > 55 dB

NOTE
If the SQI value is less than 15%, the parameter
values for BIS, BSR, BCT, SEF, and PWR will be
replaced by *** identifying them as unreliable.
If the SQI value falls between 15% and 50% a
question mark appears next to the BIS value
indicating the value may be unreliable.
If BSR is less than 5%, the BCT value will be
replaced by *** identifying it as unreliable.
