New Dreamstation Auto Bipap - lost on support settings
#31
RE: New Dreamstation Auto Bipap - lost on support settings
You asked what Min PS=0 would do,

It will do NOTHING to reduce CO2 concentration. Follow Sleepriders suggestions. None of us want to do anything to harm your wife, quite the opposite. PR machines are very slow to increase PS, thus the suggestion to increase min PS to 4.

The closest we can get to monitoring CO2 is to monitor Oxygen, so do get a pulse oximeter compatible with OSCAR.

My titration for a BiLevel was on a PR machine, It was a square wave signal and I actually had a very hard time with it. The pressure changed instantly (maybe .1 second) between inhale and exhale and not gradually but quickly. I suspect this may be what your wife felt in the hospital.

RE: New Dreamstation Auto Bipap - lost on support settings
I was just going by what you said earlier

"With the settings we recommended for your wife, the starting pressure will be 11.0/7.0 (IPAP/EPAP)"

RE: New Dreamstation Auto Bipap - lost on support settings
The key to that sentence is "starting pressure". By increasing the IPAP max, the machine is able to change pressure if and when necessary. I'm glad you called me out on it, as it is often difficult to communicate the complexity that comes with automatic or variable pressure. The starting pressure is the minimum. We give it room to adjust using the Auto BiPAP algorithm by increasing IPAP max.

I think there is an adjustment in there to adjust that delay time in between.  The machine must be in bi-level, not auto for that.  I just changed the settings.  When I gave it a brief test, the pressures were changing like I've thought they should. We wanted her to start the night at 11, she's comfortable at that.  So, now, I have 11.
  
EPAP - 20
IPAP - 7
MIN PS 4
MAX PS 5 

Camera on phone messed up right now, so I cant give picture proof (next project)... I know how to set them, just got lost and wanted the numbers, which I now have.

5 local stores, no collars that wont be too big.  We need 3 inches and all anyone has locally is 4 inch. I did find a travel pillow that we will try as a test. Better than nothing for a night or two. 

She really doesn't show all the bad symptoms form this.  Something changed a few months ago and these co2 issues started happening. We know now she has these breathing problems that can get mostly resolved.  Maybe it just as simple as more good air in, more bad air out

Russ, your settings above are wrong
Min EPAP = 7
Max IPAP = 20
MIN PS 4
MAX PS 5 

Her starting pressure will be EPAP=7, IPAP=11, and go up as needed from there.

For a very temp collar, try rolling a towel around a necktie (a wide something to tie). I'm sure you have the idea.

Russ, please, let's keep this simple. You are an acting caretaker and I'm concerned you are simply not paying attention.

Go to this link https://www.apneaboard.com/adjust-cpap-p...nual#THREE
Send an Email to Apneaboard@gmail.com
In the BODY of the email put these words: Philips-Respironics DreamStation Auto BiPAP
You will get the clinician manual for the machine.

The settings you need are:
Mode: Auto B
Min EPAP: 7.0
Max PS: 5.0
Min PS: 4.0
max IPAP: 20

Please, let's get this right. Take an image of your setup screen so we can check.

Please take a picture or your settings and post it. Let's please get this right.

That's what I have. 

I have the clinician's book. That's what drew me here. Might be more helpful to me now that I know more than I knew when I first saw it. I'll go through it again, as well as the Oscar manual.

As far as using any of this as some sort of a baseline to show improvement of her breathing in general, what data matters?  Or is all this a simple as keeping her airway open more and her normal breathing is capable expelling enough co2, as long as it's open?
