Is it possible that when I "sleep" for 10 hours my O2 sat gets down to the point where I am causing physiological damage? Anyway, GP thought it was plausible, but did not know.

Just guessing, but O2 desat could be cumulative.

The longer you sleep the longer your REM cycles are. If you have most of your events during REM (as most everyone does) then the later into your sleep, the longer the REM cycle, the more the events and the lower your O2 sat goes.

The logic sounds right, but I don't know if the conclusion is correct. Bottom line: certainly possible.

Wow! Thanks to all! I've been thinking all this time that I was the only with this problem. Frankly, I was starting to get somewhat depressed.
I too HAVE to sleep on my side/stomach, which as many know causes all sorts of problems with mask comfort/leakage. I have not tried the breeze yet but it sounds like it's the only game in town for us side sleepers.
I use the cpap every night, but awake feeling just as tired when I went to bed. I guess thats better than the pre-cpap days of feel worse than the previous evening.
Anyway, thanks again to all

Gary,

One of the other posters on this forum got a lot of help by raising the pressure up a notch. Can you do that? Without reading back through the post, I don't know if you're on auto or cpap, but either way, perhaps you can adjust the pressure just a little bit more? When we go for our studies, they titrate us based on one night when that may not even be an ordinary night for us for them to judge us on. Maybe you're not feeling well because your pressure just isn't doing what you need it to do. Just a thought. I'm so sorry you're not feeling better by now.

Comfy side sleeping was the Breeze's claim to fame for a long time. It's very good for that...for most folks. Each individual's mileage may vary, of course.

The Breeze nasal pillows interface was my favorite for almost a year. Aura by Aeiomed is even better, imho, for ANY position - side, back, tummy. Many can manage the Swift fine for side sleeping too.

As far as "cover the nose" nasal masks go, the Activa is probably best in that category for side sleeping.

I'm one of them. I'm all over the bed: left side, back, right side, and almost completely over onto my stomach. After the first few days of getting the straps "just right" and figuring out which side of the barrel I wanted the tube to enter, I was just fine. Now, the Swift follows my tosses and turns all night.

Remember: One good turn deserves another. But one really good turn gets all the covers! .

I didn't pay any attention to this post when it first appeared but I just realized after trying to nap with my Remstart autocpap that my throat closes off on the exhale when I lie on my back. The machine fails to open my throat. I have had no success with cpap, in fact I am worse with it. I still fool around with it, though, expecially since I just got a 3rd mask. I can nap with it successfully since I nap on my back and do not toss and turn as I do at night so the mask stays put. However, I feel no good results after using it. The exhalation apneas may expalin why sewing a tennis ball onto the back of a t-shirt makes me feel a little better. Unfortuantely, the t-shirt has the same effect as the apneas and the cpap---they all awaken me. I envy you sound sleepers, who can sleep with a hurricane blowing down your throat and the monster from the movie ALIEN attached to you face.

Gary,

If you have a REMSTAR Cflex you may want to lower your CFLEX number from 3 to 2, or 2 to 1. It will increase your exhale pressure a little.
