Prior to joining Dalhousie University (Halifax, Canada) in 2007, Professor Michael Schmidt was a cardiac anesthesiologist and leader of the Neuroprotect Research Group at the University of Ulm (Germany), which included the study of several aspects of xenon as an anesthetic. He holds appointments in the Department of Anesthesia, Pain Management & Perioperative Medicine, the Department of Physiology and Biophysics, and the School of Biomedical Engineering. His research interests include post-operative neuro-cognitive decline and the development of organ-protective strategies. It is tempting to speculate that his experience with low flow anesthesia to administer xenon and his “exposure” to oxygenators during cardiac anesthesia may have blended into a radical, new design of a type of CO2 absorber that might ultimately eliminate Ca(OH)2 granules as a CO2 absorbent: “No more CO2 absorber canister changes !! From CPB oxygenator to everlasting CO2 absorber”.
