I thank everyone on the board for sharing their thoughts and info it is very helpful. I have been a CPAP user now for 120 days. I was diagnosed in a sleep study overnight stay with moderate sleep apnea (20 per hour). I currently use the resmed airsense 10 with autoramp set to 15 and auto pressure. For the last 110 days all was fine, like everyone else just starting out, it takes alot of getting use to. I use pillows (resmed) and have recently tried a nose mask (resmed) but reverted back to pillows because I found that there was more leakage on the nose mask and i had a higher AHI and AI.
For the last two nights now while laying in bed but awake, I notice the machine increases pressure shortly after the ramp time is done. It increases to 14.8 and remains there until I shut the machine off. It does not come down. I have not seen this in the last 110 nights why now? Isn't the pressure suppose to fluctuate when on autopressure. Go up when you need it and down when you don't?? Is my machine defective??
The lab study showed a requirement of 10 but at a constant 10 my AHI and AI were still high around 12. When switching to auto my AHI and AI have both dropped to 7 and 5 with a central of about 5. Not sure I will ever be able to get lower than a 7.
In any event I thank those who read this and have an answer
Look at your data on your computer and see when the pressure rises and when it falls. Where it is 95% of time, and so forth.
It could be that as you lay in bed awake you are on your back and you doze off, causing your airway to partially collapse. This would make the pressure go up.
What are the pressure range (max and min) settings on your machine?

Sounds like your auto has gotten switched to straight cpap mode.
With all the modem this machine calls in that stuff it happens. Heck DME could have set your card up that way.
Its not likely any auto would go to a single specific pressure and remain there constantly, regardless of body position.
