PS [Pressure Support]
#1
VPAP Auto, Sleepyhead, Apple MacBook Pro Retina, OS-X 10.13.1.  In Sleepyhead -> Statistics lower right, it says PS 1.0 over 4.0 - 19.0.  I would like to change the PS 1.0 to 3.0.  I am in auto mode.  What do I change?
Thank you.

Go to clinic settings on your machine and change PS from 1 to 3. If you need it you can get the clinic manual in the private files section.

Larry, that is a very wide range of pressure. What is your median or average EPAP and IPAP?
Walla is correct that PS is in the clinical settings, along with EPAP min (4) and IPAP max. (19)

To enter the Clinician Mode on the S9, hold down both the Info button and the large rotary knob to its right for over 3 seconds.

Thanks to all. I do know about how to make the thing take clinical directions. The reason it's wide is because it's on auto and I wanted it to do what it wants without my restricting. My biggest problem is that I seem to have a lot of CA's and the machine can't do anything about them. I notice that I got better scores when PS was higher so I thought I would try that. My IPAP/EPAP are all over the place. It looks (from the next page) like pressure runs between 6 (EPAP) and 17 (IPAP) with about a constant 4 lb. between them. Thank you.

Hey Larry, keep in touch on this. My observation with most people that experience CA events is that they do better with more steady pressure and less pressure support. If the problem is severe, you need a bilevel with a backup rate (ASV), that can cause a breath when needed. I assume your problem is not at that level. Good luck!

That's interesting!  The last prescription I had was 14/10 CPAP.  I thought I might do better if I used the auto ability but so far it hasn't happened.  I have to tell you that I really like the low pressure where it starts, but I'm not liking the OA's, H's, and CA's that follow.  On the Software board I'm trying to get setup with a FlashAir so I can use Sleepyhead easier.  I had about 3 sleep studies.  At first I was over 20. but eventually I ended up at 14/10.  That gives me an AHI about 3.  I can't do as well with the auto so far but I can do around 5 or 6.  Thanks!

What you're describing is fairly common here on the forum, and it is an under-reported problem because it is rarely caught by doctors or sleep centers who conclude you're well treated by CPAP. It's a form a complex apnea and as pressures and pressure support rises, the breathing becomes increasingly disordered. If you're willing, I think it would really help to take a look at a typical chart on the forum.

I'm willing!  Tell me where to go or what you would have me do next!  Thanks!

Larry, simply post Sleepyhead results from your sleep therapy. Choose one or more nights and take screenshots of the Detail results in Sleepyhead. The instructions to organize and post are in my signature links. Many members have done this, and we're getting pretty good with the complex apnea problems. Wish we could say they are uncommon, but not so much. We have many members that have used the information obtained on the forum, and moved their therapy into something that works. For some ideas, take a look at posts by Richb, SpyCar, Hojo, Sarcastic Dave, and many others.
