I do not use the ramp feature as I get used to the machines pressure within the first few minutes of use. I have awakened with the pressure at 9 and 6, at all times my breathing was comfortable. I feel my nest step is to increase my pressure, be it by directly increasing the pressure or reducing the EPR. The say EPR is a comfort setting but I feel ( at least in my case) it can affect my numbers and sleep.
The other change I made was to try a "Large" pillow instead of my "medium" pillow. The air flow is more comfortable not to say the "medium" is uncomfortable. I do not see where this should affect my numbers but I feel I did sleep better with the large.
Back to the question, do I increase the pressure, or turn the EPR off? I feel either will not change my comfort position but I need to eliminate some of the sleep/wake junk and the big swings in pressure.
