METHODS AND APPARATUS FOR PROVIDING CONCENTRATED THERAPY GAS FOR A RESPIRATORY DISORDER

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)....

description	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.
