I too have to use the ramp feataure on my CPAP, as I very senstive to pressure in my nose. I am on 8cms as well but it seem that my machine is doing more then 8cms at times, as I often catch it with 5 lights on, instead of they usual 4 lights on [rectangle lights] I wonder if my CPAP's mulfunctioning or not.
But I use the ramp and I too sleep like a baby......I sleep long heavy and soundly, alot better before I started the CPAP treament for sleep apeona. I like wearing the mask, but after a few days the mask gets a bit stinky! I have to wash it before I get it put back on my face after 3-4 day's time.
I am another so called "Hose head" OR in my terms, "Snorkle mask user".
