The Brain Anaesthesia Response Monitor

Welcome to Cortical Dynamics

Cortical Dynamics ltd is an innovative Australian medical device technology company that has developed an industry disruptive brain function monitor that has been described as “paradigm busting”.

The core-product is the Brain Anaesthesia Response Monitor (BARM) which has been developed with the objective of better detecting the effect that anaesthetic agents have on brain activity, thereby aiding anaesthetists in keeping patients optimally anaesthetised.

BARM’s competitive advantage arises from its two unique measures of brain activity, Composite Cortical State (CCS) and Cortical Input (CI)1, which have been recognised by leading world experts in anaesthesia2.

The BARM is currently regulated for clinical use in Europe3, Australia and New Zealand4 with further territories to follow. Cortical Dynamics has now commenced an extensive sales campaign in Europe and the Asia-Pacific region.

An expert opinion on BARM

Dr Adrian Sultana MD, FRCP, FANZCA

Dr Adrian Sultana trialling BARM

Dr Adrian Sultana trialling BARM during 2018 has shown “significant reduction in anaesthesia recovery time using TIVA (Total intravenous anesthesia is a technique of general anesthesia which uses a combination of agents given exclusively by the intravenous route without the use of inhalation agents (Gas Anesthesia)) with the BARM”. His conclusion was that BARM was “Remarkably stable and the responsive signal permitted a new level of belief in the awareness monitoring technique and allowed him to run cases at a CCS index of 45 with confidence in early tapering “of the patients anaesthesia” using TCI (infusions of propofol and remifentanil)

Dr Sultana was very impressed with its stability and speed of response. He reported that “he was able to administer significantly less TIVA.

Dr Sultana commented that “Often when using the BIS/Entropy, they dramatically lag the patients emergence and I have had patients that take up to 20 minutes to wake up after exceeding the index of 65 on either modality, or conversely that in a rapidly changing situation, eye opening of the patients may occur before the processed EEG signal “takes off” from a baseline of the index number 35-45. However, while using BARM, my patients emerged reliably at a Composite Cortical State (CCS) index of 70.”
