18.1 Overview
Bispectral Index monitoring helps to monitor the hypnotic state of the brain based on acquisition
and processing of EEG signals. The monitor processes raw EEG signals to produce a single
number, namely BIS, which correlates with the patient's level of hypnosis. The user can view the
BIS measurement result via connected CMS.
The V-BIS module and BISx device provide the monitor with the display consisting of:
