Download and print your medical equipment tag

CPAP Machines are considered medical devices covered under the American's with Disabilities Act and do not count as one of your carry-on items.  

It's also a good idea to take your machine on the plane with you in the event that your luggage gets lost or damaged in transit.

The TSA recommends labeling your carrying case with a medical equipment luggage tag, but this is not mandatory. 

You can download tags templates here and laminate them on your own or you can purchase a laminated tag from a qualified online retailer.
