finally, your chart are almoste there...thanks.

How do your feel this night?

Your chart is plagued by plateaued type unflagged FL, as well as arousal/awakenings. examples: 4;30 false OA following awakenings, unecessary bump in pressure. 5;38...false OA, awakening before REM, 6:30 ..awakening....6;50 likely another REM.
It looks your are having some architeture; this is good.
However, your I:E  index  close to 1.0 is clearly compromised.
It appears there would  not be much doubt left you could benefit a lot from going to BPAP.

good luck

I only slept 1/3 of the night with CPAP due to early awakening from water in mask so I can't really say. What do you mean by plateaued type unflagged FL, a flattening of the inspiratory curve? What does I:E index mean? Wouldn't I be best trying a higher EPR value first? Is this the post you're talking about?

Yes, I think it would be wise to see if the EERS allows you to tolerate higher EPR first, and then see how things look.

"Flattening of the inspiratory curve" is when the normally smooth top of the airflow curve is not smooth, but jagged. This indicates breathing restrictions that can cause arousals. 

You normally fix this with higher EPR/PS; sometimes more than the 3 that a Resmed CPAP can offer.

To expand a bit, early in this thread, Sleeprider  noted you have flow limitations that suggest you may benefit from bilevel, but centrals appeared to preclude that.

But it looks like EERS may remove that restriction.

Please, let's wait a few days keeping the current settings and getting a solid EERS baseline before making any other changes.

Of course, this precludes seeing anything that could be dangerous which would need an immediate change, something that I don't expect to find.

And with all changes, can we keep them a bit slower than we typically see. Why, because this is the first user we have a chance to the impact of EERS with so let us not cloud the data with multiple changes. And please frequent charts and impressions from the user. Let's keep this well documented. I want to be able to apply this to many other users.

Sleeprider, can you add an EERS label to this thread for searchability.

Yea I'll stick with the same settings and post all the data in a few days  Coffee
Nothing I post is medical advice and should not be taken as such, always consult a medical professional for guidance.

If you figure out a good solution for the rainout of the EERS hose, please post it. This is a new frontier, so best to document solutions as we discover them.

This seems a trend with EERS here (my one-night experiment, and Joey's case): that it lowers CAs, and raises TV/MV.

RE: Interpreting sleep study results, EERS enhanced expiratory rebreathing space
If it isn't convenient to acquire or to use a hose sleeve for some reason, I lay mine across my midriff under the top cover.  It works both to keep the hose from sagging back toward the machine, which will happen easily, and to keep it warm with minimal temperature set in the hose climate control. I never have rainout in my hose using this method.  Granted, it won't work for everyone, but if you sleep relatively sedately, and don't toss and turn much, you will get used to turning over on your side with the hose across your waist.

I used this technique when I tried EERS the one night, but to cut down on noise from the swivel vent. It worked for that.

I did also get rainout, but not sure why (if it happened despite using this technique, or not), since I wasn't paying attention to that.
