I've had a hard time telling what my pressure actually gets up too, I am thinking maybe 16 I am not sure tho, as I don't see any of that info on my new machine, need to investigate it more. I know it's high. (pressure when I originally started using cpap was set a 8, now it is set to adjust to what I need that works better for me.)
You know if you think you've used your ramp time up before drifting off, just restart the machine and it will start over with a fresh 45 mins of time. I know I've had to do that sometimes where it's taken longer to fall a sleep. I am real happy with my new machine that I got early Spring, I can track my sleep on my iPhone although sometimes it claims that I am sleeping better than I thought I did. The other night I scored a 100 on sleeping and for once I would agree with it as I did sleep really good that night, been battling some upper respitory (sp) crud and doing alot of coughing, used NyQuil and slept very soundly. ( Wed evening) But my usual score is between 96-99, but I'll have to see if I can find what level the air pressure is at when I am sleeping the most soundly, I know I snore really, really bad, and I am overweight which doesn't help. The more you use your machine the more comfortable you will become with it, I can't live with out it. Power outages at night are the pits and really lead to nights of distrubed sleep......lol
