  2. High altitude breathing apparatus - Wikipedia

    en.wikipedia.org/wiki/High_altitude_breathing...

    Pulse dose (also called intermittent-flow or on-demand) portable oxygen concentrators are the smallest units, which may weigh as little as 2.3 kilograms (5 lb) Their small size enables the user to waste less of the energy gained from the treatment on carrying them. The unit administers a set volume (bolus) of oxygen enriched air at the start of ...

  3. Oxygen concentrator - Wikipedia

    en.wikipedia.org/wiki/Oxygen_concentrator

    An oxygen concentrator takes in air and removes nitrogen from it, leaving an oxygen-enriched gas for use by people requiring medical oxygen due to low oxygen levels in their blood. [4] Oxygen concentrators provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generation plants.

  4. Portable oxygen concentrator - Wikipedia

    en.wikipedia.org/wiki/Portable_oxygen_concentrator

    Portable oxygen concentrator used with bottle humidifier. POCs operate on the same principle as a home concentrator, pressure swing adsorption. [6] The basic set up of a POC is a miniaturized air compressor, a cylinder filled containing the sieve, a pressure equalizing reservoir and valves and tubes.

    Demand Valve Oxygen Therapy (DVOT) is a way of delivering high flow oxygen therapy using a device that only delivers oxygen when the patient breathes in and shuts off when they breathe out. DVOT is commonly used to treat conditions such as cluster headache , which affects up to four in 1000 people (0.4%), [ 1 ] [ 2 ] [ 3 ] and is a recommended ...

    A chlorate candle, or an oxygen candle, is a cylindrical chemical oxygen generator that contains a mix of sodium chlorate and iron powder, which when ignited smolders at about 600 °C (1,100 °F), producing sodium chloride, iron oxide, and oxygen at a fixed rate of about 6.5 man-hours per kilogram of the mixture.

  8. Fluidized bed concentrator - Wikipedia

    en.wikipedia.org/wiki/Fluidized_Bed_Concentrator

    A fluidized bed concentrator for VOC control at Honda Manufacturing of Alabama. [1] A fluidized bed concentrator (FBC) is an industrial process for the treatment of exhaust air. The system uses a bed of activated carbon beads to adsorb volatile organic compounds (VOCs) from the exhaust gas. Differently from the fixed-bed or carbon rotor ...

  9. Concentrator - Wikipedia

    en.wikipedia.org/wiki/Concentrator

    A concentrator usually provides communication capability between many low-speed, usually asynchronous channels and one or more high-speed, usually synchronous channels. Usually different speeds, codes, and protocols can be accommodated on the low-speed side. The low-speed channels usually operate in contention and require buffering. [1]
