3-38
Ground Check
A test is performed immediately after every sensor check and at 10-minute intervals during
monitoring to check the status of the patient ground connection. During the test, the EEG
display shows a flat line and the message “GROUND CHECK” displays on the screen
Diagnostics
The BIS VISTA monitor provides diagnostic codes to assist the user in tracing the source of
any problems that may occur. Codes are displayed above the Message Region only if the user
has requested them in the Diagnostic Menu.
3.10.4 Monitor Data Memory
The monitor stores recorded trend data with time and date of acquisition. The duration of
trend data stored is approximately 72 hours. Trend memory can be viewed on the screen in
Review Mode.
When the memory is full, the oldest data are automatically erased as new data are stored.
Memory will be retained even if the battery has been discharged and remains when the
monitor is in the power off condition.
3.10.5 BISx Data Memory
The BISx stores processed EEG parameters, including the BIS value, with time and date of
acquisition. History data stored in the BISx can be accessed by exporting it to a removable
drive using the “Export Data” function. The duration of BISx data stored is approximately
1200 hours.
To view BISx history for a specific case, the user must first identify which BISx was in use
during the case by looking up the BISx serial number in the Maintenance Menu’s “BISx
Connection History.” The appropriate serial number BISx can then be connected to any
monitor to export its History Data.
When the BISx memory is full, the oldest data are automatically erased as new data are
stored. Memory will be retained even if the monitor battery has been discharged and remains
when the monitor and BISx are powered off.
