RE: Mouth Leaks = CAs?
First a CA event won't increase pressure. The machine will reduce pressure in response to a CA event. For links on cervical collars you can try Amazon or your local drug store. There is not any one soft collar that works for all. You'll have to measure yourself and than try them on. As far as the time of night when your having mouth leaks it could be as simple as you rolling to your back at that time each night.
RE: Mouth Leaks = CAs?
a question and a few comments.
WW, is that right? does an apap respond to ca by lowering pressure? I've never understood what an apap does with respect to ca, if anything. it does ID them so it I guess it responds somehow.
isuck, I just shopped around town at the pharmacies for a soft cervical collar. surprisingly hard to find but Walgreens has 2, one adjustable and one not. both under $20. good place to start, otherwise people seem to shop online for wedges (front only, strap around back of neck) like dr dakota or a wrap around like releaf caldera or something like that. might take a few tries to find best for you.
the worst part of my night for snoring, leaks and events is in the later part of the night / early morning like somewhere between about 3 and 6. that's when I tend to get my longest sleep sessions and presumably reach deepest sleep when everything goes lax so not surprising it might happen to you too.
I believe mouth leaks can sometimes be identified in flow rate, particularly with non ffm's I think, by series of reduced magnitude exhales.
