10 years with a CPAP, just had another sleep study done.

Thanks!
Right, Sadie. The 4- 20 range that is set in autopaps at the factory will include the single pressure from any regular cpap titration.

A person could use it that way, sure. Quite a few people, though, find that 4 or even 5 just doesn't feel like getting enough air through a mask. Some also seem to find they get smoother, more effective treatment by using an autopap with the lower pressure up fairly close under (or even on) their titrated pressure. One would naturally ask, "Well, what's the use of having an autopap if you're gonna use it almost like a straight cpap?!"

For me, I like having a margin of mostly unused pressure up above, just in case more is needed sometimes during the night, or on occasional nights. My "prescribed" single pressure would probably be any one of these -- 9, 10, or 11. When using an autopap I set my range at 9 - 16. It rarely hits 13 or 14 briefly on some nights. I've used lower minimum pressures in my range, like 7 - 16 and 6 - 16. But I can actually feel my throat slam shut if I let it relax at low pressures while drifting off to sleep. Knowing that, I elected to keep my minimum pressure on autopap up where that doesn't happen.

Others prefer keeping the lower pressure down fairly low to minimize mask leaks, aerophagia, noise, etc. Some use a very, wide range and do fine.

Still others find that they do better with just a single straight pressure.

The beauty of an autopap is its versatility. You can tweak around until you find a range that suits you. Or even use it as straight cpap, single pressure.

THANK YOU, CPAP GODDESS!!

One thing I don't understand though...(always that 'one' thing). I "thought" that if I 'demanded' via inhaling a certain amount of 'pressure', that's what I would get, HOWEVER, I SHOULD NOT BE IN CONTROL OF THAT, right? I'm learning as I'm typing and sorta thinking this over.
I DO have a range set on my APAP w/C-FLEX, which is GREATER than that from either of two sleep studies! I set it 7-11, but found it held at 11, so uppped it to 13. Need to do some readouts on that now, to see what's going on. Could be the cause of some snoring, which I guess is OK occasionally.

So, if one uses an APAP with a very wide range, they're probably not getting the amount of pressure they need, correct?

Thanks so much for the information, and causing me to think this latter part through for myself...IF I'm right, that is! .
