Contact the Airline
Not all airlines allow the use of portable oxygen concentrators. Check with your airline before flying. Also check with the manufacturer to determine whether the oxygen concentrator is approved for in-flight use.
Inform the TSA Officer
Inform the TSA officer that you have a portable oxygen concentrator and whether you can disconnect during the screening process.
Consult your doctor to determine whether you can safely disconnect during screening.
Screening in Standard and TSA PreCheck® Lanes
If you are able to disconnect from the concentrator, submit it for X-ray screening and continue to the AIT or WTMD.
If you must remain connected, your equipment will be tested for traces of explosives material.
Standard screening

Nebulizers, CPAPs, BiPAPs and APAPs as well as facemasks and tubing may remain in their carrying case for X-ray screening, but may be required to be removed from the carry-on.
Precheck screening
Nebulizers, CPAPs, BiPAPs and APAPs as well as facemasks and tubing may remain in their carrying case, and in the carry-on, for X-ray screening.
