Never put it in your checked baggage. There are plenty of Youtube videos about what baggage handlers do with the bags for you to put an expensive piece of medical equipment -- but of course I am preaching to the choir.
You can bring a CPAP onboard as a 3rd piece of carry-on. I've never had to argue the point but it is in the airline regulations. I find of course that it is logistically problematic with the overcrowding of flights these days and have a carry-on that will hold the CPAP safely plus my clothes and then bring the laptop bag and I am good to go.
