When I was using a nasal mask, I thought that i was getting no leaks and my machine seemed to think so too. When I got the software and reader and started looking at my data, I found that I was mouth leaking quite a bit and It was effecting my AHI. I recommend that you get Sleepyhead and a card reader if you do not have one and check it out. Sleepyhead is free and there is a li9nk at the top of each page to get it. USB SD card readers are cheap and very available.
Just some comments.
When the mask and hose are new they are such a bother to us that they can interfere with our ability to sleep well. Yes, they serve the purpose in that they allow us to breathe when we are asleep, but their presence may cut down on the amount of time we spend sleeping.
The good news is that we're human. Humans have a remarkable ability to adapt to new situations. So after awhile we get used to it and it doesn't bother us anymore.
