18.1 Overview
Bispectral index (BIS) monitoring is used to monitor the level of
consciousness state of patient with general anesthesia or sedative treatment in
the operating room and intensive care unit. BIS monitoring involves putting a
BIS sensor in patient's forehead to receive, filtrate, and process the patient's
EEG signals through the BISx module. Through bispectral index and power
spectrum analysis, a BIS value which can represent the consciousness level of
the patient can then be obtained. Furthermore, by using this method, patient's
level of consciousness state can be comprehensively evaluated and depth of
anesthesia can be determined based on EEG signals.
18.2 Safety Information
Warning:
The conductive parts of electrodes, sensors, and connectors can't
contact other conductive parts, including the ground.
To reduce patients’ risk of ecrasement, the monitor must be placed
carefully and the patient interface cable must be immobilized.
When a defibrillator is used for patients, the BIS sensor can't be
placed between the pads of the defibrillator.
In high-frequency surgery, when the electrodes are connected, the
BIS sensor cannot be put between the surgery units and the return
electrode of electrical surgical equipment in case of burns.
When brain stimulation components are used, to reduce the risk of
combustion, the stimulation electrode should be placed far away from
the BIS sensor. Meanwhile, the sensor should be placed according to
the instructions for use.
