1. Normal night: AHI=.8 avg, pressure ranges from 4 to 12, leaks are near zero, both the mask and pillows are comfortable.
2. If I set the S9 to CPAP and pressure of 4, I get an AHI of .3 with only 1 or 2 events total per night. This is the same with the pillows or full face mask. Seems odd, but I like it. Makes me wonder why in APAP mode it ramps the pressure up to 12-14 a couple of times a night. Based on the CPAP mode and 4 pressure, that isn't necessary.
3. The pillows are amazingly comfortable. But for some reason, I seem better rested after a night on the full mask. No leaks with either and I don't mouth breath and the snore index is always zero these days. Thought this was strange and causes a dilemma as to which mask to use. I love the pillows for the comfort and I can use my glasses with them. I love the full face mask because I don't know what to do with all the energy the next day. Although I am infinitely more rested with the pillows than I was without CPAP. Just a curious result that I cannot trace to root cause.
That's it. Since starting this a month ago I've started to eat right, exercise and I can go all day without a nap (been a long time since that has happened). I travel a lot (4 days / week, multiple cities) and didn't think I would lug the S9 around but I won't go anywhere without it. Gives me my edge back.
I did get lucky and my Medical Savings account covered the cost of the machine and equipment. Now trying to get TriCare to pay for the ongoing supplies. Speaking of which, why do I need a new mask every 3 months? If it still works, why replace it? I can understand if insurance is paying, but so far this has all been self funded.
Thanks to everyone on the board. Without your help, I never would have tried this out and that would have been unfortunate. Life is good.
