A system for providing a NO-containing gas flow to treat a biological object. The system includes a nozzle receptacle for receiving NO-rich air from a plasma-generated NO source, tubing coupled to the nozzle for directing the NO-rich air to a scrubber, the scrubber configured to receive a solvent for absorbing NO2, tubing coupled between the scrubber and a gas mixer for directing scrubbed NO-rich air to the gas mixer, where the gas mixer is coupled to a source of atmospheric air for selectively mixing the scrubbed NO-rich air with the atmospheric air to create diluted NO-containing air; and a manifold for distributing the diluted NO-containing air to a plurality of patient locations.

The present disclosure generally relates to systems and methods for delivery of therapeutic gas to patients, in need thereof, receiving breathing gas from a high frequency ventilator using at least enhanced therapeutic gas (e.g., nitric oxide, NO, etc.) flow measurement. At least some of these enhanced therapeutic gas flow measurements can be used to address some surprising phenomenon that may, at times, occur when wild stream blending therapeutic gas into breathing gas a patient receives from a breathing circuit affiliated with a high frequency ventilator. Utilizing at least some of these enhanced therapeutic gas flow measurements the dose of therapeutic gas wild stream blended into breathing gas that the patient receives can at least be more accurate and/or under delivery of therapeutic gas into the breathing gas can be avoided and/or reduced.

Various examples disclosed relate to an apparatus and method for use in verifying input gas, such as differences between a first and a second gas in an anesthesia flow control where one of the gases is oxygen gas and the other of the gases is nitrous oxide gas. The apparatus can include, for example, a chamber having an inlet to receive gas and a vent to exhaust the gas, a gas control to fill the chamber with the gases to a determined begin pressure, and a microprocessor configured to measure respective times to exhaust the first gas and the second gas from the chamber, via the vent, to reach a determined end pressure. Based on time to exhaust the respective gases, a difference between the first and second gases can be identified; this verification can verify that improper crossover/ross-connection of gas supply lines is not present.

Medical gas delivery devices are provided. A garment or another object may include a hose assembly configured to couple the garment or the object to a medical gas source. The garment or the object can be configured to deliver a medical gas to a patient. Additionally, medical gas delivery devices configured to be removably coupled to a garment or another object are provided.

An apparatus for administering a respirable gas to an individual includes a body receivable against a facial area for enclosing a respiratory organ, a vacuum hose, and a scavenger valve. The body is cup shaped, and includes a first side and a second side. An inhalation member extends from the first side of the body. An exhalation member extends from the second side of the body. The vacuum hose is for coupling a vacuum source to the exhalation member. The scavenger valve is coupled to the vacuum hose. The inhalation member is for administering respirable gas into the body, the exhalation member is for exhausting exhaust gas from the body into the vacuum hose, and the scavenger valve is for exhausting exhaust gas therethrough from the vacuum hose to an atmosphere.

This disclosure includes a method for treating a patient suffering from alcohol withdrawal. The method comprises administering an effective amount of oxygen to the patient and administering an effective amount of nitrous oxide to the patient. In some embodiments, the effective amount of oxygen and the effective amount of nitrous oxide are administered to the patient via a nitrous oxide sedation system.

A signaling apparatus for an anesthesia machine, the signaling apparatus comprising an user input sub-module for receiving input information from an user, an available gas sub-module for signaling types of currently available gases according to information of the user input sub-module, and an available gas outlet sub-module for signaling currently available gas outlets according to information of the user input sub-module.

An arrangement and a process filter out at least one gas from a gas mixture. A filter unit (4) of the filter arrangement comprises an inlet and an outlet and is adapted to filter the gas out of the gas mixture while the gas mixture flows through the filter unit (4). The filter unit (4) takes up the gas and heats up in the process. A filter temperature sensor (46, 46.2) of the filter arrangement is adapted to measure at least once an indicator of the temperature in a first measuring area (MP, MP.2) inside the filter unit (4). Depending on the measured temperature, a message is generated and output in a form perceptible by a human being. This message includes information about the current state of the filter unit (4).
