   [1] The scrubber canister uses potassium superoxide as both a carbon dioxide absorbent and as an oxygen source. A sodium chlorate oxygen candle in the base of the unit generates oxygen on start-up as the canister has to reach a high internal temperature before it will start generating oxygen.

[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 ...

5. High altitude breathing apparatus - Wikipedia

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

   At high enough altitudes the partial pressure of oxygen in the air is insufficient to support useful work and consciousness, even after acclimatisation, and at even higher altitudes it cannot support human life. At altitudes where the problem is hypoxia, breathing gas with a higher oxygen content at ambient pressure is a viable solution.
