2. High altitude breathing apparatus - Wikipedia

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

   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).

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.

5. 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.
