The system log can hold up to 1,000,000 records or up to 50 cases, whichever is
smaller. (The system log differs from the monitor log in that it includes data about the
system as well as data about the patient.) If the log reaches a capacity of 50 cases, the
earliest complete case will be deleted upon the opening of a new case. If the log
reaches a capacity of 1,000,000 records, records (but not a complete case) will be
deleted upon the addition of new records.
Data recorded in the log will be retained even if the monitor battery has been
discharged and will be retained when the monitor and BISx are powered off.
5.3. BISx Data Memory
The BISx stores processed EEG parameters, including the BIS value, with time and
date of acquisition. History data saved in the BISx can be accessed by exporting it to a
removable drive using the Download function. The duration of BISx data saved 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,
as follows: Main Menu>Settings and Maintenance>Maintenance>Logs>BISx
Connection log. The appropriate serial number BISx can then be connected to any
monitor to export its History Data.
To download BISx history, connect the relevant BISx unit, but do not connect a
sensor. Attach a USB flash drive to the monitor. Select Main
Menu>Download>BISx Saved Cases>Download. The BISx memory will be
downloaded.
