OT CPAP issues for sleep apnea

You should have a setting on your machine that lets you start out at a lower pressure and then build up to your recommended pressure. Call the place you got your machine from. Somebody there should be able to help you with being able to use it.
There are lots of different models of CPAP/BiPAP machines out there... some are Rolls Royces and some are Hyundais... they'll all get you where you want to go, but the Rolls have a lot more features than the Hyundais.

IOW, not all machines have this ramping feature you mention here, where you lie down at a lower pressure and then it gradually increases, allowing you to fall asleep at some point and then just sleep at the therapeutic pressure you need. I personally hated using the ramp feature on my machine and had it disabled (turned off), but some folks love it. She mentioned that she thought the pressure was set too high. I had that problem... my doc ordered my pressure set at 21 (which is very high) because my sleep study showed that it was the highest setting I needed to keep the apnea at bay during that study night. But it was way too high, so I complained, and we set it way down (I think to 6), which was way too low and I couldn't sleep. So gradually we upped it and upped it some more until we arrived at my present 14, where I've stayed for 3 years. I'm fortunate to have a Rolls machine that has an auto titration feature. I go to sleep at 14/12 (I have a BiPAP) but the machine will give me more pressure if it senses I need it during the night. The recording device inside has shown that I spend most of my night at 18/16, with only very occasional forays as high as that orginal 21.

So anyhoo, as you can see, when you first get your machine, you have to be willing to complain, readjust, keep fudging with it, and above all, at some point, you just have to bite the bullet and wear the damned thing. There's no other way to get used to it except to just DO IT. It doesn't take long, maybe 2 or 3 days, before it starts to feel like part of you. It's a marvelous feeling, to be able to breathe when you sleep, and very restorative. By the way, the machine techs can up your pressure at any time if you want, but if you want the pressure set down, it takes doctor's orders to okay it.
