Oxygen concentrator

An oxygen concentrator, as PATH and CHAI describe it (2021), is a medical device that draws in ambient air and passes it through molecular sieve beds to remove nitrogen, delivering typically 90% to 96% oxygen; ISO 80601-2-69:2026 sets its basic safety and essential performance requirements.

The 2020 edition of ISO 80601-2-69, revised by the 2026 edition, covered concentrators that increase the oxygen concentration of gas delivered to a single patient; the 2026 edition applies to transit-operable and non-transit-operable oxygen concentrators. PATH and CHAI give output pressures of 30 to 135 kPa and power requirements of 300 to 600 W. ISO 7396-1:2016 excludes oxygen concentrators for domiciliary use from its scope, and the International Pharmacopoeia monograph for medicinal oxygen (2025) does not apply to oxygen from portable concentrators for home care or bedside use.

WHO-UNICEF technical specifications (2019) name compressed gas cylinders, oxygen concentrators and oxygen plants as the three most common sources of medical oxygen in health care facilities in low-resource settings. The ISO 80601-2-69:2026 abstract states that the standard does not specify requirements for oxygen concentrators for use with a medical gas pipeline system. Ultra Controlo also uses the term inside its central plants: ULTRACON is the oxygen concentrator of ULTRAOX plants, with two molecular sieve columns and a zeolite adsorbent, and its table runs from 0.32 to 111.4 Nm³/h at 93%.
