The Respironics Oxygen Enrichment Adapter is used to introduce oxygen into the CPAP/Bilevel airstream. It is commonly installed where the breathing tube connects to the machine. The pressure line from an oxygen concentrator or tank can then be connected to the fitting on the adapter. The fitting adapter can be closed when oxygen is not required. Please consult with the owner's manual for your oxygen concentrator and/or CPAP or BiLevel machine for details. Pk/10
