The displayed impedance value will flash to alert you if the values are out of
range.
Filters
You can set the low and high cutoff filters and line frequency filter in the system
parameter menu. The low cutoff filter determines the lowest frequency that is
displayed and processed, and the high cutoff filter determines the highest
frequency that is displayed and processed. The LINE FREQ key selects either
50Hz or 60Hz line frequency.
Touch the FILTERS key to enter the sub-menu where the high cutoff, low cutoff
and line frequency filters are set.
Touch one of the keys (0.5Hz, 1.0Hz, 5.0Hz) to select the desired low cutoff filter.
The key will be highlighted.
Touch one of the keys (20Hz, 32Hz, 50Hz, 70Hz) to select the desired high cutoff
filter. The key will be highlighted.
Touch LINE FREQ and select 50Hz or 60Hz. The selection will be highlighted.
Remote Monitors
This section covers the differences in display format and user menus between the
local bedside monitor and remote monitors. EEG cannot be displayed on a split-
screen central monitor and remote monitors do not have access to all keys and
functions that are available at the local bedside.
Bed Name / Patient Name Interference
If the EEG key is not selected then bed name and patient name are displayed at
the bottom of the display zone on remote monitors. This conflicts with display of
the EEG data. When the EEG key is selected bed name is displayed on the
message line instead.
Display Formats - Remote Bedside
EEG uses one, two or four display zones at the local bedside, depending on how
you configure the module. Remote views at bedside monitors only use one
display zone to display the remote EEG data.
Case #1 - One display zone used at the local bedside (2 EEG channels, dual
format off).
In this case, the remote display of EEG data is almost identical to the local
bedside’s display of that data (refer to Figure 24-11).
