Continuing research
Dr David Humphrey, who trained in London and is a well known research anaesthetist. He has won two research awards for his work on the ADE system, one being from the Royal Society of Medicine, London. He is currently involved in research with sevoflurane in low-flow techniques, particularly in veterinary applications.
If you would like to invite him to lecture on "Safe, simple low flow anaesthesia" or contact him about any issue connected with the ADE-circle system or on low flow techniques, please see "Continuing Professional Development" on Home page.
