Passenger Hypoxia Protection Utilizing Oxygen Enriched Gas Mixtures
Currently, existing civil aviation standards address the design and certification of oxygen dispensing devices that utilize oxygen sources supplying at least 99.5% oxygen. This Aerospace Information Report discusses issues relating to the use in the passenger cabin of oxygen enriched breathing gas mixtures having an oxygen content of less than 99.5% and describes one method of showing that passenger oxygen dispensing devices provide suitable hypoxia protection when used with such mixtures.
Rationale: There is increased interest within the aviation oxygen community in the possibility of using on-board oxygen concentration systems to supply oxygen-enriched breathable gas mixtures having less than 99.5% oxygen content. This Aerospace Information Report provides information that supplements standards addressing other aspects of passenger oxygen dispensing device performance, such as AS8025A.
