default speed is 12.5mm/s . The larger the value, the faster the wave sweeps.
3) Display
Select “ Display ” drop-down menu to set BIS waveform type for display. BISx is a
dual-channel EEG signal monitoring device for unilateral cerebral hemisphere BIS monitoring.
Waveform display options are
EEG I
,
EEG II
, and
Trend
. When you select
EEGI
or
EEG II
,
EEG I or II waveforms are displayed in the BIS waveform area; When you select Trend, BIS
real-time trends are displayed in the BIS waveform area.
4) Trend Interval
Select “ Trend Interval ” drop-down menu to set Trend time interval for display. You can
select 2s, 6s, 12s and 24s. The default setting is 2s . You can set the Trend Interval only when the
Display
is
Trend
.
5) Parameter1
Select “ Parameter1 ” drop-down menu to set Parameter1 for display in BIS parameter area.
You can choose: SR, TP, SEF or BC. BC is only visiblewhen Extended sensor is used.
6) Parameter2
Select “ Parameter2 ” drop-down menu to set Parameter2 for display in BIS parameter area.
You can choose: SR, TP, SEF or BC.
BC
is only visible when Extended sensor is used.
7) EEG WaveformScale
WaveformScale is shown in the form of gridlines, corresponding to the magnitude of the
scale line. Select “ WaveformScale ” drop-down menu to chooses 50μV, 100μV,200μV or 500μV.
8) SmoothingRate
Select “ Smoothing Rate ” drop-down menu

Select 15s, 30s, 60s or 10s. The default
smoothing rate is
15s
.
The smoothing rate defines how the monitor averages the BIS value. With the smoothing rate
becoming smaller, the monitor provides increased response to changes in the patient’s state.
Contrarily, the monitor provides a smoother BIS trend with decreased variability and sensitivity to
artifacts.
9) High-pass filtering
（
HPF
）
With BIS filters you can filter out disturbances from the EEG signal and improve thesignal
quality. Select “ HPF ” drop-down menu to set High-pass filtering frequency

Select: OFF,
30Hz, 50Hz, 70Hz, the default setting is OFF .
10) Low-pass filtering (LPF
）
With BIS filters you can filter out disturbances from the EEG signal and improve the
signal quality. Select “ LPF ” drop-down menu to set Low-pass filtering frequency

Select: OFF,
0.25Hz, 1.0Hz, 2.0Hz, the default setting is
OFF
.
