Abstract: The invention relates to a device for supplying gas to a patient, in particular a patient breathing spontaneously. The device includes a) a metering device (A) which is used to meter the gas to be inhaled by the patient (P) into the gas tank (B), b) a gas tank (B) which is used to store the gas to be inhaled by the patient (P), c) a demand valve (D) which regulates the volume flow of the gas inhaled by the patient (P), d) a reservoir (F) which is used to hold the gas exhaled by the patient (P), e) a carbon dioxide separating unit (G) which is used to separate carbon dioxide from the exhaled gas, f) a pump (H) which is used to return the exhaled gas purified of carbon dioxide into the gas tank (B), and g) an analysis/control unit (J) which analyzes the gas returned to the gas tank (B) and controls the metering device (A) according to the composition of said gas.

Abstract: A device is described for making available a respiratory gas (mixture) to a patient, comprising means for making available one or more gases and means for delivering the respiratory gas (mixture) to the patient, their being assigned a respiratory air line that is connected to the surrounding area and in which a negative pressure valve is arranged. According to the invention, the negative pressure valve (D) is dynamically connected to a device for generating a warning signal (C, E), preferably an acoustic and/or optical warning signal.

Abstract: A method and system for the controlled admixing of at least one gas or gas mixture to a gas (mixture) flow, so that, after the admixing to the gas (mixture) flow, the gas or gas mixture has a preadjusted and/or preadjustable concentration in this gas (mixture) flow by use of a pressure controller.

Abstract: The gas-supply system for the inhalation treatment of humans or mammals, entailing controlled dosing of at least one gas, characterized by a tidal volume-dependent regulation of the gas dosing.

Abstract: The gas-supply system entailing controlled dosing of at least one gas or at least one aerosol is characterized by a control means for a dosing whereby the feed of the gas or aerosol into a breathing gas starts at a defined point in time during the expiration of a patient.
