I'll dial it back to what you suggested and make small changes from there. I was actually looking at nasal masks on line yesterday thinking that that may work better for me, so I may try one soon. I don't believe I have any respiratory issues as I am in pretty good shape, at the proper weight for my height, never smoked, don't drink, and I stay active and excercise. I just feel like when I exhale that I am not putting out as much exhailation pressure during the last half of my exhale as the CPAP is forcing into the mask. Kind of like trying to fill a tire when the tire has more pressure in it than the air compressor is putting out.
Thanks for the suggestions. I'll put them to work!
Remember, that with the exception of the inhale/exhale ration, the first night after you make changes will not generally give a good record of what your experience will be. You need to run for maybe 3 nights to see how you're doing.

So I'm wondering if perhaps you should consider a different type of mask. Either a nasal mask or a pillows mask. At the bare minimum I think it would be a good idea for you to find your favorite comfy chair recliner (hopefully) and sleep in it for a day or two at the new settings until you get used to exhaling as much as you inhale.
I find it very difficult to believe that the mask is making it difficult to exhale. The Mirage Quattro has a lot of vent area compared to masks of other types and so should make it a little easier to exhale. I would look at pressures first and a medical check up.
I agree Payton that it's not likely a mask issue per se', but a change to a different kind of mask may alter the body's tendencies as to how to relate to the mask during inhale/exhale, and therefor change the ideology of the experience. (I do not know what that means......)
