Bispectral Index™ (BIS™) Monitoring System

Bispectral Index™ (BIS™) monitoring enhances the clinician’s patient-targeted approach to induction, maintenance, and emergence. BIS™ technology non-invasively measures and interprets brain wave activity directly related to the effects of anaesthetic agents.

Among other benefits, BIS™ technology:

• Helps the clinician customise anaesthetic dosing to individual patient physiologies
• Indicates hypnotic effect through the easy-to-­read BIS™ index
• May be associated with improved patient outcomes as validated in multiple clinical studies([FOOTNOTE=Gan TJ, Glass PS, Windsor A, et al.

Brain monitoring is an adjunctive technology that should not be used as the sole basis for diagnosis or clinical decision-making.
