So here I am, the past few weeks trying to figure out why I've been having high AHI's. I've got one of the most expensive machines on the market and yet some nites I have a 6 or 7. Others an 8 to 10. And still others, I'll have a 15 or 16. I even had a 20 a couple of weeks ago. But NO 5's or under.
Earlier in this thread, it was recommened that I lower my Min PS and EPAP to try and increase my AHI. It didn't work.
So I put my setting back to prescription strength and that's where I've been at.
But 2 nights ago, I saw this:
Of particular note is the last hour where my PTB's flatline at 0...I'm not doing any breathing on my own whatsoever. Yet my AHI during that time is 0. I had an AHI of 6 for the night.
And that's when it hit me. The machine was acting as a ventilator and
pressure support is at it highest, yet I had no AHI's during that time until my breathing picked up again and the pressure dropped.

So last night, I decided to up my Min PS and EPAP. I upped my MinPS to 6 and my EPAP from 7 to 8.
And last night's report is a 3! I haven't had a 3 in months:
------------------------------------------------------------------------------------------------------------------------------------------------
That's not the whole night, I woke up about 6 am and pushed the Min PS up to 7 and EPAP to 9. (So Encore Pro broke down the night into 2 reports even though sleep was almost continuous). And below is my last 90 minutes until I woke up this morning,
No AHI's.
So, I am cautiously optimistic and hoping I am on to something here. I'm going to try this again tonite and see if this continues it to be successful.
