BIS™ Advance Monitor System Indications and Contraindications
BIS™ Advance Monitor
25
For both the 2-channel and the 4-channel systems, BIS™ monitoring is implemented
as follows: A sensor placed on the patient’s head transmits EEG signals to the BISx
module. The BISx module filters the data, analyzes it for artifacts and processes it
using digital signal processing techniques, then sends the data to the monitor for
display. The purpose of processing the EEG waveform data is to extract characteristic
features from the complex signal in order to provide easier pattern recognition of
changes over time during the recording. A list of the processed variables and a
description of each is provided in Table 1. The BIS™ Advance Monitor Parameters, on
page 31. This data is displayed on the screen according to the preferences set by the
user in the menu system.
