High-altitude climbing usually requires the use of portable oxygen apparatus when climbing Mount Everest or the other eight-thousanders, though some mountaineers—and alpine style climbers in particular—have deliberately ascended Everest without oxygen (e.g. starting with Reinhold Messner in 1978).
A lightweight portable oxygen concentrator: Inogen One G3 (2,2 kg) Sequal Equinox, transportable concentrator with a high oxygen flow rate A portable oxygen concentrator (POC) is a device used to provide oxygen therapy to people that require greater oxygen concentrations than the levels of ambient air.
Most commercial aircraft that operate at high flight altitudes are pressurized at a maximum cabin altitude of approximately 8,000 feet. On most pressurized aircraft, if cabin pressurization is lost when the aircraft is flying at an altitude above 4,267 m (14,000 feet), compartments containing the oxygen masks will open automatically, either above or in front of the passenger and crew seats ...
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. [1]
An oxygen hood is a plastic hood used for high flow oxygen therapy in infants. It surrounds the head and has an opening for the neck. A high flow rate is necessary to prevent carbon dioxide accumulation. Supplied gas must be warmed and humidified. [37] oxygen mask An oxygen mask is an interface between an oxygen delivery system and the human user.
The emergency oxygen supplied to passengers in commercial airliners that have lost cabin pressure is also a basic form of built-in breathing system, where the oxygen is generated and supplied as a constant flow for a limited period, which should be sufficient to allow the aircraft to safely descend to an altitude where the ambient air oxygen ...
