Checking the Impedance

Impedance checking is an important part of BIS monitoring because it tests the quality
of the BIS electrode connections. Make sure that the BIS sensor passes the impedance
check before starting BIS monitoring to avoid misleading BIS data. To optimize
performance, check the individual electrode status (provides a smoother trend with
decreased variability and sensitivity to artifact in addition to the overall status.
Individual electrode impedance value may display " ***", even though the overall
impedance passes).
To check the BIS impedance

The BIS impedance menu, depicted below,
classifies the status of each electrode.
Pass - Indicates that the impedance check
has passed based on the combined
electrode impedance values. You can exit
the impedance menu and resume normal
monitoring.
Fail - Indicates that the impedance check
has failed. In this case, do the following:
— Press the electrodes firmly to in place to provide good contact.
