Abstract: The invention provides new systems/methods for providing oxygen to chronically ill patients, such as COPD patients, through a more efficient portable oxygen concentrator (“POC”) that at least sometimes delivers an enriched airflow having a significantly lower overall oxygen concentration than that administered by typical POCs. In aspects, the methods/systems of the present invention are configured to automatically switch from pulse delivery to continuous delivery, from continuous delivery to pulse delivery, or any combination thereof, at least once per day, when certain conditions occur. Methods/system can comprise the ability to switch between mode(s) comprising delivery of a moderately enriched oxygen airflow (MEOA) and mode(s) comprising delivery of intensively enriched oxygen airflow, highly enriched oxygen airflow, or both, and back again, based on one or more parameters.
