2. Portable oxygen concentrator - Wikipedia

   en.wikipedia.org/wiki/Portable_oxygen_concentrator

   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. It is similar to a home oxygen ...

3. Oxygen concentrator - Wikipedia

   en.wikipedia.org/wiki/Oxygen_concentrator

   Research into oxygen concentration is ongoing, and modern techniques suggest that the amount of adsorbent required by medical oxygen concentrators can be potentially "reduced by a factor of three while offering ~10–20% higher oxygen recovery compared to a typical commercial unit." [15] The FAA has approved the use of portable oxygen ...

4. Emergency oxygen system - Wikipedia

   en.wikipedia.org/wiki/Emergency_oxygen_system

   Pulling down on one oxygen mask starts the oxygen supply for that mask only. The entire system can usually be reset in the cockpit or in some other location in the aircraft. [citation needed] A decentralized gaseous system, often called a pulse oxygen system, [4] is used on some modern airliners such as the Boeing 787. These systems have a ...

   Some airlines will provide cylinders for passengers with an associated fee. Other airlines allow passengers to carry on approved portable concentrators. However, the lists of approved devices varies by airline so passengers may need to check with any airline they are planning to fly on.

6. High altitude breathing apparatus - Wikipedia

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

   The unit administers a set volume (bolus) of oxygen enriched air at the start of each breath, which is the part of the breath most likely to reach the gas exchange regions of the lung beyond the physiological dead space. Their ability to make efficient use of oxygen is key to keeping the units compact. [18]

   en.wikipedia.org/wiki/Glossary_of_breathing...

   [citation needed] There are three basic types: a manual version (also known as a bag valve mask) consisting of a mask and a large hand-squeezed plastic bulb using ambient air, or with supplemental oxygen from a high-pressure tank. The second type is the expired air or breath powered resuscitator. The third type is an oxygen powered resuscitator ...
