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:

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

Product Technology

BIS™ monitoring technology provides valuable information about the status of your patients to help address each their unique anaesthetic requirements.

BIS™ technology offers the clinician added security for providing specialised critical care and comfort for their patients, including those who may be more sensitive to the haemodynamic effects of anaesthesia.

BIS™ monitoring provides invaluable information about patient status to help clinicians address their unique anaesthetic requirements. This may be particularly valuable for:

  • Patients with complex conditions whose status may suddenly or frequently change
  • Patients with cardiovascular conditions
  • Obese patients
  • Trauma patients or others requiring reduced levels of anaesthesia
  • BIS™ monitoring technology enables clinicians to manage anaesthetic goals of hypnosis, analgesia and immobility.
  • BIS™ monitoring technology enables clinicians to assess consciousness and sedation separately from cardiovascular reactivity.
    • Reduce emergence and recovery time2
    • Reduce anaesthetic drug use2
    • Reduce the risk of awareness during surgery5,8


"BIS™ monitoring is recommended as an option for all patients receiving total intravenous anaesthetic (TIVA). BIS™ technology is also cost effective in this patient population due to the inability to measure end-tidal anaesthetic concentration."([FOOTNOTE=National Institute for Health and Clinical Excellence.
