摘要：
A method of filling a portable tank with compressed oxygen-enriched gas includes the steps of providing a coupling such that when a portable tank is connected with the coupling oxygen-enriched gas can flow through the coupling into the portable tank; directing oxygen-enriched gas from an oxygen concentrator to a compressor; compressing the oxygen-enriched gas in the compressor; directing compressed oxygen-enriched gas from the compressor to a reservoir; storing the compressed oxygen-enriched gas in the reservoir; and thereafter directing stored oxygen-enriched gas from the reservoir to the coupling to enable filling of a portable tank with compressed oxygen-enriched gas from the reservoir.
