Claim 10:
11. A method of a controller of an oxygen concentrator apparatus, the method comprising:
receiving a flow rate signal in the controller, the flow rate signal generated with a flow rate sensor that is pneumatically coupled to (1) an accumulator for oxygen enriched gas produced by the oxygen concentrator apparatus, and (2) an outlet for the oxygen enriched gas; and
evaluating, in the controller, the flow rate signal to detect an onset of inhalation by a user of the oxygen concentrator apparatus;
controlling, by the controller, a delivery valve to release, to the outlet, at least one bolus of oxygen enriched gas based on the detected onset from the evaluation of the flow rate signal from the flow rate sensor; and
monitoring, in the controller, the flow rate signal during release of the at least one bolus.
