    Abstract: The concentration of xenon, in a medical gas mixture of xenon as an active component with a known composition of oxygen and, optionally, nitrogen and/or helium recirculating through a medical device (103) in which carbon dioxide is introduced into the mixture, is monitored by removal (135, 133) of carbon dioxide downstream of the medical device (103) and subsequently passing the carbon dioxide-free gas through an ultrasonic gas analyser (143) upstream of the medical device. The gas analyzer determines the xenon concentration by measuring the time delay between transmission of an ultrahigh frequency ultrasonic pulse of at least 100 kHz axially through the sample chamber from a location at one end thereof and reflection of said pulse axially from the other end of the sample chamber back to said location. An analyser of novel construction is disclosed.

    Abstract: A medical device (103) is supplied (105) with a gas mixture from a higher pressure section of a main circuit (102) in which medical gas recirculates though the higher pressure section and a lower pressure section. Decontaminated spent gas is returned to the lower pressure section of the main circuit Pressure in the higher pressure section is maintained by a pressure maintaining valve (141) and gas flow in the main circuit is maintained by a volume regulator (145) in the lower pressure section. The composition of the recirculating gas mixture is maintained by addition of respective feed gases in response to concentration and/or volume variation measurement. The method has particular application to the feed of a binary oxygen/xenon mixture to a cardiopulmonary bypass oxygenator or an artificial ventilator.
