The accuracy of the IL404 oxygen alarm monitor has been tested against oxygen/nitrogen mixtures of known composition. The effects of inhalational anaesthetic agents and of changes in flow rate, PCO2 and humidity have also been investigated. The instrument was found to be sufficiently stable and accurate for clinical use and was unaffected by the presence of volatile anaesthetics, change in gas flow rate and the presence of nitrous oxide, carbon dioxide or water vapour. The instrument incorporates an efficient alarm system which gives both audible and visible warning should the oxygen concentration fall or exceed pre-set limits.
