Fred, I think the better option might be increasing EPR to 3. What do you think?

So a follow up on the ear pain/drainage issue.

I tried dropping the pressure to 11 for a few nights and my AHI numbers crept up (2.5 ish). The ear issue remained. Next I put the pressure back to 12 and changed the EPR to 2 (was at 1) and the AHI went back down to almost 0 - no change for the ear however. Last night I changed the humidity level from 5 to 4 and there seemed to be a small improvement. I'll leave it for another night or 2 before making further changes.

No improvement in the ear pain after a few days of reduced humidity. I am at a loss about how to proceed. The drainage into my throat is a serious problem as it's making me hoarse. I am a professional musician/singer and having an inflamed throat long term is going to be a career killer.

I noticed a comment on another thread about ear pain that having higher EPR (keep pressure more constant) seemed to be helpful but that would put me back where I started with an EPR at 1. These issues began with machine switch so there has to be some pressure related component.

Any suggestions about what changes I could make to improve things?

Reviewing your entire thread.

I'd like you to try 2 different things.

First, as SR suggested, try EPR=3.  This is using EPR to treat your flow limitations.  Then post your charts for review.  

if that doesn't work
For comfort reasons I would like you to drop your max pressure way down, (your flow limits will try to raise it to where you are at now)
Set your Max Pressure to 8.  Why, Your original machine, the 760P, was providing pressure at 7.5 (med) for the entire night.  let's try that.  That is a radical change, a MUCH larger change that we normally would ask for.  I'm not sure what that will do for your therapeutic treatment, likely increase your AHI, but let's see if we can help that ear pain some. And, for now leave the EPR at 3 (from the previous night).  (that lowers the pressure for your exhale portion of the breath cycle in addition to treating your flow limits.

And an update. .. I raised the EPR to 3 - no change. Next I tried lowering pressure as suggested - that latest about 2 hours.

Finally I went to see my primary care doc to have my ear examined. Seems I have developed something called eustachian tube dysfunction - fairly common and hopefully treatable with some steroid based nasal sprays. Hopefully it's not related to cpap use.
