I wonder .....
Hey! Berneta
Do you have an APAP or a CPAP, I can't remember? I suspect you have an APAP, not just because you are in America, but because I think that sudden rush of air has little to do with your ramp function and a lot to do with you having an apnoea when, or very soon after, you fall asleep. I don't know how algorithms vary machine to manufacturer - or what yours is - and whether the auto response is higher in the hierarchy than the ramp or whether it is disabled, even, during the ramp period (to do with whether or not you would get the rush if you had an apnoea during the ramp peroid).
If you have a CPAP, that theory is blown (ha ha) and I suggest the machine needs servicing.
If you have an APAP, you could overcome or reduce the effect of that blast of air by setting your maximum pressure closer to your set pressure or your 90% pressure - or ask your CRT to do it. If the difference between your 90% and maximum pressures is large, I definately recommend it - always subject to your CRT agreeing.
There is no point in a sleep enhancing machine that wakes you up!!
As regards that suffocating feeling during the ramp period - I bet you can fix that by increasing the ramp start pressure. Not only will that help overcome feelings of not having enough air but it will also help make the mask more comfortable/easy to adjust. Ah! that last is true for full face masks, which you don't use, and maybe for nasal masks/pillows/prongs - I don't have experience.
Good luck and sweet dreams. I'm supposed to be doing yesterday's ironing, not posting here!!
