I love the machine and the mask. I was on it for a month and was getting AHI's of around 1.7 to 3 until I decided I needed a chin strap that then put me down to 0.6 to 1.2 AHI. My omly problem was that at a constrant 10Cm h2o, I was very bloated during the day amd expelling it a lot. When I found out that I could set my machine to APAP, I did so and set it for 8 to 13 cm h20. After doing that I no longer had the bloating and I noticed my 90% is 9, so I have not been hitting my prescribed 10 cm. However, since going to APAP, my AHI"s have increased to 2.6 to 3.3. I know that I am ok if I am below 5 but I am wondering if I should set my lower limit closer to 10 if it gives me better readings? I am afraid I will go back to the bloating then. Should I stay where I am at and be comfortable and forget about the higher readings, or try to adjust for the lowest AHI?

Hi tsmith3605,
You could move your starting pressure to 8.5 and see if that makes a difference for you as long as you don't experience the aerophagia. If you do, then move it back down. I know that can be a "pain" to deal with. Don't make too many changes, give it time to work; maybe a week to 10 days.

The only other thing is if you are tracking your therapy on sleepyhead, check and make sure where your max pressure is. Does it goes as high as 13? If not, you can lower it by .5 also. This way you would be at 8.5 to 12.5. Sometimes the small changes make a big difference.

A lot of people don't feel that the max pressure is a concern, but with the system one machines, they will raise the pressure in response to flow limitations and snores, even if no apnea event is present. That rise in pressure can affect your sleep, but in your case if the pressure goes up to 13 may cause more aerophagia, which is what you want to avoid. So watch that for awhile and if the max doesn't rise that high, then you are pretty safe in lowering it a bit.
