The DME guy said that would be 15 and according to the prescription they would set it for that on this coming Tuesday, the end of my 2 weeks. I have written my physician and asked to change the prescription. I feel suffocated at the level 4 and whenever the machine gets anywhere close to 15, I wake up and stare at the clock until my 4 hours are up, for compliance reasons, then take the darned thing off. I can't sleep at that high pressure. Most of the time, it doesn't need to be that high, so I asked the doctor to change the prescription to start the ramp at 6 then go to an automatic variable between 9 and 16. I have not heard back from her, yet, but it is the weekend. I would also like to have some exhalation relief, but the technician said that the doctor would have to prescribe that, too.
Setting your pressure at the 95th percentile is a bit much. The best bet is to stay in auto mode and set the minimum pressure to the median pressure. This takes a lot of the pressure swing out. For CPAP mode, the 90% value is usually used.
Resistance may be futile, but the settings are very easy for YOU to change. Passive resistance would dictate letting the DME and doctor be happy setting up your machine. Then bring it home and reset it where you know it should be.
Get Sleepyhead, do it now. Do the setting changes yourself before your appointment. I suspect that you will avoid the sense of air starvation, and the machine won't adjust up as high when the minimum pressure avoids many of the precursor events.
