Claim 11:
12. A method of assisting breathing in a patient having low blood oxygen saturation, the method comprising:
(a) providing the patient with a portable oxygen concentrator that delivers an enriched oxygen airflow, wherein the portable oxygen concentrator comprises:
(1) a pressure gradient generating system,
(2) at least one nitrogen adsorption media that generates an enriched oxygen airflow when exposed to air and acted on by a sufficient pressure gradient and that is selectively isolated from the ambient environment by at least one air enrichment area separator, and
(3) an enriched oxygen airflow outlet that is fluidly connected to a flow line and a patient oxygen delivery interface,

(b) causing the portable oxygen concentrator to deliver an enriched oxygen airflow to the patient for a period of at least 1 month, the delivery of the enriched oxygen airflow comprising
(1) generating a moderately enriched oxygen airflow comprising an oxygen concentration of 33-48% and
(2) pulse delivering to the patient at least about 300 ml of the moderately enriched oxygen airflow per average inspiration of the patient, and
(3) changing between pulse delivering the moderately enriched oxygen airflow and a continuous delivery mode wherein the continuous delivery mode comprises the portable oxygen concentrator automatically
(I) generating an intensively enriched oxygen airflow comprising an oxygen concentration of at least about 60% and
(II) continuously delivering between about 640 ml and about 1200 ml of the intensively enriched oxygen airflow per average inspiration to the patient, and

(c) operating the portable oxygen concentrator at up to 3.125 watts per liter per minute.
