What does a BIS monitor measure?

The BIS monitor is the first quantitative EEG index introduced into clinical practice as a monitor to assess the depth of anesthesia. BIS technology measures only the hypnotic component of anesthesia. It consists of a sensor, a digital signal converter, and a monitor.

What is BIS monitoring in ICU?

Bispectral index (BIS) monitoring, an objective measure of the patient’s response to sedation, has been used in anesthesia for over a decade. This technology is finding its way into the ICU to provide a means of assessing the adequacy of sedation and preventing oversedation of critically ill patients.

What is a BIS sensor?

BIS™ sensors collect electroencephalograph (EEG) data. BIS™ technology enables simple EEG data collection via a noninvasive sensor applied to the patient’s forehead.

When is BIS monitoring used?

A bispectral index (BIS) monitor is commonly utilized to assess depth of sedation when administering sedative, hypnotic, or anesthetic agents during surgical and medical procedures. The depth of sedation is calculated by measuring cerebral electric activity via an electroencephalogram (EEG).

Are BIS monitors accurate?

Additionally, the results of small randomized controlled trials and prospective cohort studies show that, overall, BIS monitoring is relatively good at indicating the state of being alert; however, its algorithm does not accurately predict an unconscious state.

What is normal BIS range?

BIS values range from 0 to 100. A value of 0 represents the absence of brain activity, and 100 represents the awake state. BIS values between 40 to 60 represent adequate general anesthesia for a surgery, values less than 40 represent a deep hypnotic state.
