I actually had a problem a couple of years ago with American in Madrid. They almost would not let me board with my CPAP because I had a battery, which AA had told me to get in order to use the machine onboard when I had called for authorization before my trip. Then, they kept asking me, "does it produce oxygen?" I told them that it did not, but only blew air. It took a total of an hour and a half at checkin before they finally gave me my boarding pass and allowed me to board.
