BIS™ Brain Monitoring System

By providing insight into the direct and patient-specific effects of anaesthesia on the brain, the BIS™ brain monitoring system helps clinicians determine and administer the precise amount of drug to meet the needs of each individual patient, leading to increased patient anaesthesia satisfaction.

Advanced Monitoring for Improved Outcomes

Bispectral Index™ (BIS™) technology was the first clinically proven and commercially available direct measure of the effects of anaesthetics and sedatives on the brain.

BIS™ technology enables medical professionals to reliably gauge the precise amount of anaesthetic medication required by each patient, resulting in better overall patient care.
