Reviving this thread rather than start a new one...

Fine.
But that's no reason for you to come back with the same settings you had when the thread started.

?? I didn't. I've changed the settings as I was advised to: minimum of 6, maximum of 10. Before it was 4 and 10.

You did. I was so impressed by your snoring and flow limitations seeing the machine reporting a minimum of 4 that I only saw that you did nothing with the ramp, despite three people suggesting you do not leave it at 4 for 45 minutes.

In your new settings, you raised the minimum pressure to 6, but by raising EPR from 2 to 3 you caused you exhale pressure to be lower. In other words, even when your inhale pressure goes up to 7, you drop to 4 when you exhale. And 4 is too low and seems to have exacerbated both the snoring and the flow limitations. The machine isn't responding quickly enough when your breathing switches from exhaling to inhaling.

Yes, it was a respected forum member who recommended raising your EPR from 2 to 3. I'd say your trial shows that doesn't work in your case. First thing I'd do if this was my data is take EPR to 2, so that your exhale pressure isn't that much lower that your inhale pressure.
