An apparatus for enriching respiratory gas with oxygen, wherein the entire enriched respiratory gas can be taken from an absorber bed and the enrichment concentration is adjustable by action on the total flow through the adsorber and the portion of the total flow in excess of the consumer flow is removable via an outflow, is improved so that adjustment of enrichment concentration and consumer flow independently of each other is possible and the enrichment concentration is maintained also at fluctuating consumer flow. To this end a control circuit for the stabilization of the set enrichment concentration is provided, to which is connected a control section for the adjustment of the consumer flow, and an outflow being is arranged at the junction between the control circuit and the control section.
