  2. Oxygen concentrator - Wikipedia

    en.wikipedia.org/wiki/Oxygen_concentrator

    An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream. They are used industrially, to provide supplemental oxygen at high altitudes, and as medical devices for oxygen therapy .

  3. 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.

  4. Flow-restricted, oxygen-powered ventilation device - Wikipedia

    en.wikipedia.org/wiki/Flow-restricted,_oxygen...

    The main components of flow-restricted, oxygen-powered ventilation devices include An inspiratory pressure safety release valve. A trigger or level positioned to allow both hands to remain on the mask to provide an airtight seal while supporting and tilting the patients head. A peak flow rate of 100% oxygen at up to 40 L/min.

  5. High altitude breathing apparatus - Wikipedia

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

    Bottled oxygen, more broadly known as high pressure compressed oxygen, medical oxygen, and aviator's oxygen, is oxygen in small, portable, high-pressure storage cylinders. For aviation, the weight of the cylinder is usually not critical, and the choice of material may be affected by economic considerations such as purchase price and useful ...

  6. Continuous positive airway pressure - Wikipedia

    en.wikipedia.org/wiki/Continuous_positive_airway...

    Helmet used as a CPAP oxygen delivery interface. CPAP therapy uses machines specifically designed to deliver a flow of air at a constant pressure. CPAP machines possess a motor that pressurizes room temperature air and delivers it through a hose connected to a mask or tube worn by the patient.

  7. Breathing gas - Wikipedia

    en.wikipedia.org/wiki/Breathing_gas

    A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas. Other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft, submarines ...

    Average mortgage rates edge higher for 30-year and 15-year terms as of Wednesday, December 18, 2024, as the Federal Reserve is set to conclude its final policy session of the year.

  9. Zeolite - Wikipedia

    en.wikipedia.org/wiki/Zeolite

    Zeolite-based oxygen concentrator systems are widely used to produce medical-grade oxygen. The zeolite is used as a molecular sieve to create purified oxygen from air using its ability to trap impurities, in a process involving the adsorption of nitrogen, leaving highly purified oxygen and up to 5% argon.
