Been using APAP since 2008 and used the ramp for the first week or so, then shut it off. It's not a problem for me to start at therapeutic pressure, and that is my preference. I found ramp to be a bit suffocating.
I started on an APAP with wide open 4-20 range. So for me, there was no ramp. But after a few weeks, I raised the minimum to 5. Then to 6 in two weeks. And then to 7 after two weeks. And I do feel relieved to be breathing ample air at 7 vs. the feeling of labored breathing at 4. But I went up slowly otherwise I don't think I could handle 7 on first day.
So in this way, its a sort of a ramp but I tried each starting pressure for at least 2 weeks to get comfortable.
A strategy you can take is (if the A10 Elite) allows it, is to have the ramp start pressure go up 1 notch every 10-14 days. This way, you will soon eliminate the need for a ramp to 7 as you will start off at 7. So do the ramp from 4-7 for 10 days, then do ramp from 5-7 for 10 days. Then 6-7 and then finally no ramp needed at 7.
Started APAP 4-20, Closed range to 7.5-14, then straight 8.0 w/ Aflex 3
RDI always below 1. But sleep much much better at straight pressure.
Started on F10, Tried Quattro Air successfully. Finally settled on P10.
never saw the need so never used the ramp
I don't use the ramp because I when I put my mask on, I like to wiggle it around to eliminate any tendency to leak. That's easier to do if the pressure is at least at the minimum of my auto range.
It is good that you can use the CPAP without ramp. At your therapeutic pressure there really is not much ramp anyway. There are some whose therapeutic pressure is much higher and utilizing the ramp is nice. It is nice for the ramp feature to not be a necessity. Way to go.
