RE: Quick Setup question for PRS1
I can only speak for myself, but my System One will hike the pressure up to whatever max I set if it determines Flow Limitations and Snores, which in my early treatment I experienced many FL, Snores, and RERA's. And that hike in pressure would ultimately wake me up, so I keep my max setting to 2cm above my 90% number. On occasion, I encounter FL and Snores that will send the pressure right up to my maximum setting of 13, with no other apnea events in site, and I don't want it going any higher if not needed. Hope that makes sense.

Hi, cate. This thread has some discussion of reasons for capping max pressure. See post(s) by vsheline in particular.

Thanks green wings! It's good I guess to avoid the possibility of increased Centrals and increased Intraoccular pressure. Good catch!

RE: Quick Setup question for PRS1
These machines have algorithms in them that are tuned for the "average" user, you might say. But none of us are "average". While the algorithms are pretty good for a lot of people they do not work for everyone. If I leave my machine open at the top it goes pretty close to 20 and seemingly tries to blow the mask off my face. BUT it doesn't make my AHI any lower. In fact at a steady pressure of 11 with EPR set at three my AHI is pretty well always under one and zero maybe half the time. I'm not the patient this particular machine was designed for, although it works just fine as a CPAP machine and keeps my AHI low. But a low AHI doesn't help me much on its own because my 02 levels on the machine alone go very low even though no or very few apneas are recorded, obstructive *or* central. So they added oxygen in during sleep and that made the difference. I still want the positive pressure to prevent the obstructive events and to get good data on how I am doing.

Of course I am probably an outlier with very unusual requirements, but still since most of us aren't average it makes sense to me that many of us will be better off without the machine set to run "wide open".

X1 will work for any ffm or nasal mask.

As for pillows id set to 0. There are several x settings for different pillow masks in the repironics line. Id doubt you would hit the right pillow setting guessing.


The x setting has nothing to do with leak rate, everything to do with machine overcoming mask resistance to flow and pressure.
Use O on non respironics pillows
