Yes, it works. I travel with a CPAP in my rollaboard. I take just the motor portion (the pump itself) out and bin it like I would a laptop. They recognize it as a CPAP and will do a simple swab test. In some cases, they offer to take it to the table and swab it while I get everything back together... If you leave it in the carryon bag, you will get a bag check.

There have been other threads about sanitary issues. I personally don't think there's a problem, but remember that you can ask for the screener to use fresh gloves when handling your CPAP. You can also pack disinfecting wipes if you really want worry about it. The screeners should NEVER need to examine or handle the hoses and mask. If they try, scream bloody murder and demand a supervisor.
