This disclosure provides an oxygen delivery and reclamation system that supplies breathable oxygen-enriched gas to one or more users in a chamber. The one or more users receive oxygen at specified oxygen level setpoints. Exhalation air from the one or more users may be purged from the breathing loop using one or both of a recycle pump and an electronically actuated valve. Exhalation air in a purge line and optionally chamber air pulled from the chamber may be recycled using an oxygen concentrator. The oxygen concentrator generates oxygen-enriched gas and oxygen-depleted gas, where the oxygen-enriched gas may be delivered back to one or more users in the chamber.
