[Treatment] Still fatigued, history, are these CAs real?

Look into a weighted blanket if you haven't tried one yet. Keeps me from moving around so much.

What to watch.
All the standard apnea, obstructive and central defined events.
Flow Limits
Not expecting issues but Tidal volume, minute Vent, respiration rate, shift in inspiratory vs expiratory ratio.
O2 levels, I forgot that one.
and a blue oval type chart.  I liked that one for seeing what is going on.

edit, and Leaks as they represent venting at the mask.

A single section of 6-9inch tube is only 58 mL of rebreathing space. Don't be too disappointed if another section or two is needed.

Well, this didn't work. I put the EERS extension on and discovered that the Corr-A-Flex tubing appears contaminated -- air flowing through it gets an incredibly strong, musty/moldy odor. I don't think it's safe to breathe that. I'll be getting some more tubing from another source.

While you are sorting out parts, you might enjoy reading about another member that just started EERS http://www.apneaboard.com/forums/Thread-...Now?page=2

Looks like EERS is becoming quite the "in" thing, at least here on the forum.

[Sleeprider]

I don't know if it's an "in" thing, but it works well for some people willing to try it out and fabricate the EERS. The results have become pretty predictable, improving respiratory volume and drive while reducing CA events. It sure beats paying for ASV in marginal cases of CAI.

[GuyScharf]

While I wait for the new Corr-A-Flex tubing, I am continuing to lower pressure to see what happens.  Last night I used 8.8 - 8.8 with EPR=3.  I am beginning to see a few OAs. Here is the whole graph and the 3 OAs from last night as well as the usual sample of H and CA.

Do you have comment on the OAs?

            

[Sleeprider]

The OA event here is not anything to be worried about. I think you are approaching the minimum effective pressure, and once we get EERS up and running, you may be increasing pressure a bit and adding in EPR. I think bonjour will agree that with EERS the exhale pressure relief should be tolerated without CA, and I think you will see improvement in the flow limitation. I think that was his original intention.

[Gideon]

Yes, EERS to fight the CA and a higher EPR to address the flow limitations. To deal with both I expect either the 12 or 18 inch deal space segments to be needed, but one step at a time.
