  • Patent number: 7703455
    Abstract: An apparatus for supplying respiratory gas to a patient in which respiratory gas components are metered with great accuracy and sources of error are detected early. The apparatus has metering devices for respiratory gas components which are connected, on the leading side of a mixing chamber volume, to a ring line; a first respiratory gas analyzer on the trailing side of the mixing chamber volume; a second respiratory gas analyzer at a patient connection; a regulating device for the respiratory gas components which controls the delivery of respiratory gas components, as a function of the concentration measured with the second respiratory gas analyzer, in such a way that the difference between a predetermined concentration and a measured concentration at the patient connection is minimized; and means for performing a plausibility comparison between the measured values of the first respiratory gas analyzer and the second respiratory gas analyzer.
