The present invention provides new devices, systems, and methods for delivering enriched oxygen to recipients (e.g., chronically ill patients, such as COPD patients). One aspect is a more efficient portable oxygen concentrator that is configured to deliver an enriched oxygen airflow having a significantly lower overall oxygen concentration and greater overall volume administered as compared to currently marketed or known portable oxygen concentrators. Administering the lower oxygen concentration at higher volumes allows for the present portable oxygen concentrators to deliver an equivalent number of moles of oxygen as administered by traditional portable concentrators while increasing the efficiency of the system and the ability of the system to maintain the therapeutic level of oxygen concentration for a longer period.
