BIS™ Advance Monitor
Ground Check and Combined Sensor
Check
The monitor automatically performs a ground check every ten minutes during
monitoring, to ensure that the sensor is positioned correctly on the patient. During
the ground check (duration approximately 5 seconds), EEG values will not be
collected, but the BIS™ value will continue to be displayed. If the results of the
ground check indicate a problem with the sensor, an on-screen message will display
this information; if there is no issue, monitoring will resume automatically.
Combined sensor check mode is the performance of ground check and sensor check
at the same time. The monitor automatically performs this combined check during
monitoring. If the results of the ground check indicate a problem with a specific
electrode on the sensor, an on-screen message will display this information (so that
this can be corrected, perhaps by adhering that sensor section better to the patient);
if there is no issue, monitoring will resume automatically.
3.6.4. Case ID
A unique Case ID will be generated automatically by the BISx module when a sensor
is attached to the system and passes the sensor check.
To view the current Case ID, click on the ID icon or the small arrow to its right; it
appears just to the right of the time on the upper right side of the screen. The ID
window will open, displaying the Case ID. If required, record the Case ID in your
institutional records. This window will automatically close in one minute. In Figure 28.
Case ID Indicator on Home Screen, below, the ID window is seen next the ID icon.
If there is no sensor connected to the BIS™ system, no Case ID is assigned and the ID
window is disabled and cannot be viewed.
If a sensor is attached to the system, and then detached and re-attached, the monitor
will automatically resume the case with the same Case ID.
