Were you retested or how do you know your apnea is gone?

No it's not!

You must take everything VERY seriously or you'll be punished!

Oops!

Run hours?

Are you on any new meds? Are you using a humidifier? Are you in a new place where humidity is lower than old place? Some hints would be helpful, like which model of what machine, what pressures, etc. etc. Can you download Oscar (see Stickies) and provide some info?

Would she be willing to try wearing some kind of backpack (even a fanny pack thing) to keep her from flipping when asleep?

If you can manage not to sleep on your back, your hypopneas should lessen by a lot. Try it for a few nights and you might just be surprised.

Can you please go to your Profile and add which model of what machine you use? And what mask? Then download (free) Oscar from the Stickies at the top of the page and post results in this thread... if it won't work (things are full here) then use e.g. Imgur.com and put a link here to those results.

Not sure what you're asking about being 'normal', but of course since the heat applies to the water in the tub, the tub will overheat (and stink) if water's used up - so don't let it go dry, or make sure to refill if it does.

And I was thinking to raise your max pressure because it looks like it's 'capping' the min. that might want to go higher to deal with obstructives... aerophagia aside for the moment. I don't understand why your min. and max are overlapping on Oscar. I suppose you could try both ideas because leaving...

Cpap keeps your throat open, not your nose.

Does it matter why it happens?

I would just set the min. pressure a bit higher and maybe it will help.

99% of us never (or soo rarely) clean the hoses - nothing but air ever goes thru them at any time.

Even if the DME's had some way to see your data, tho' nothing at all as comprehensive as Oscar, they are NOT MDs and cannot prescribe anything, whatever they tell you, plus while they know the machines, they don't know medicine, tho' always want to advise. Please don't take your info from them.

Have you installed Oscar (see info Stickie top of messages)? Post results here and the experts will help you interpret and suggest any adjustments that might need making.
