I strongly suspect that in the unrecorded gaps the machine simply does not detect my breathing and stops recording any data. Of course if it can't detect any breathing it can't treat any events that I might have. One night I had the machine going for 8 hours but just under 3 hours of data was present and there were some huge gaps. I felt like crap when I got up that morning.
I've tried to cover all the possible issues including power supply, faulty SD card, etc. I have turned off both the auto start and auto on but this has changed nothing.
Before I return the machine I am wondering if the resistance setting might affect the machine detecting my breathing. I use a Dreamwear mask yet Respironics doesn't seem to have a setting for it. All their other nasal masks use setting 1 so this is what I used for the Dreamwear. But as the Dreawear has two vents this may be wrong.
Any thoughts on this would be appreciated. I'd like to cover all the bases before returning the machine all the way to the US from Australia only to find that the problem was an incorrect setting.
