Abstract: Oxygen concentrator apparatus provides variation in therapy gas during a breathing cycle such as by varying flow rate and/or oxygen purity of enriched air. The apparatus may include a compressor and a valve set that operates sieve bed(s) for the enriching air and to vent exhaust gas from the bed(s). The therapy gas may include released enriched air and exhaust gas. The apparatus has a supply valve to selectively release enriched air from an accumulator via a primary path to a delivery conduit. The apparatus may include a secondary path, such as with a valve, to release a portion of exhaust gas to the delivery conduit. A controller actuates the valve set to produce the enriched air, and the supply valve to release enriched air to the delivery conduit. The controller may actuate the secondary valve in anti-sync with the supply valve to release exhaust gas to the delivery conduit.

Abstract: Systems and methods for managing the power consumption of an oxygen concentrator are disclosed. An oxygen concentration system may comprise a compression system, a canister system, one or more processors, and at least one of a pressure sensor or a movement sensor. The one or more processors may be configured to transition the oxygen concentration system to at least one of a prescribed mode of operation or a standby mode of operation. The timing of the transition may be based on at least one of a number of breaths detected from the pressure signals generated by the pressure sensor or an estimated energy content of the movement signal generated by the movement sensor. A predetermined volume or concentration of oxygen enriched air may be supplied to a user during the prescribed mode of operation. A reduced power may be provided to the compression system during the standby mode of operation.
