I know that most personnel at security checkpoints in airports are familiar with CPAP machines. t’s advisable to carry along your prescription and/or statement of medical necessity from your physician so that you can demonstrate the need for your CPAP machine.

I found from different sources that many CPAP users report no problems getting through the X-ray machine and passing the subsequent explosives and chemical tests, while others are forced to check their CPAP machines because they don’t pass the X-ray check.

My recommendation would therefore be to expect to be able to take your CPAP machine on an airplane with you, but don’t be surprised if you end up having to check it. And don’t forget your prescription from your doctor!

Good luck!
