An oxygen concentrator system with altitude compensation includes at least o ne oxygen concentrator sub-system and a plenum subsystem. The at least one oxyg en concentrator sub-system produces oxygen-enriched air which is outputted to both the oxygen concentrator system output and to a plenum chamber within the plenum subsystem. The plenum chamber is trickle charged with the oxygen-enriched ai r when the at least one oxygen concentrator sub-system produces an excess amount of oxygen- enriched air. Should the demand for oxygen-enriched air exceed the capabilit y of the at least one oxygen concentrator sub-system, additional oxygen-enriched air is provided by the plenum chamber until such time that the capability of the at least one oxygen concentrator sub-system exceeds the demand for oxygen-enriched air. At that time, oxygen-enriched air is no longer provided by the plenum chamber but rather t he plenum chamber is again trickle charged. A monitor/controller having an absolute pressure transducer controls the cycle times of the oxygen concentrator subsystem in accordance with an ambient barometric pressure measured by the absolute pressure transducer.
