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 ...

   pulse dose oxygen conserving device demand pulse device Oxygen delivery device that senses the start of inhalation and provides a metered bolus, which if correctly matched to requirements, will be sufficient and effectively inhaled into the alveoli. Such systems can be pneumatically or electrically controlled. [60] pulse oximeter

   A similar function is provided by a mechanical demand regulator which provides gas only during inhalation, but requires some physical effort by the user, and also ventilates dead space with oxygen. A third class of system (pulse dose oxygen conserving device, or demand pulse devices) senses the start of inhalation and provides a metered bolus ...

   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.

7. 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 ...
