Zusammenfassung:	Methods and apparatus provide controlled operations in an oxygen concentrator (100) such as by adjusting valve opening time to regulate amount of oxygen enriched air released to a user. The apparatus may generate, with a sensor configured to sense pressure at a location associated with accumulation of enriched air produced by the concentrator, a signal representing measured pressure of the accumulated enriched air. The apparatus may generate, with a sensor, a signal indicative of respiration of a user of the concentrator. The apparatus may include a controller configured to receive the measured pressure and respiration signals. The controller may control, responsive to the respiration indication and according to a target duration, actuation of a valve adapted to release a bolus of accumulated oxygen enriched air. The controller may dynamically determine the target duration during the release of the bolus according to a function of a value of the measured pressure.
