Still getting high Hypopneas
[attachment=1671]Hi everyone I've recently taken delivery of a Resmed S9 Autoset and going great with the data reporting etc, but these reports have confirmed to me something that has pretty much plagued me from day one - namely, high hypopneas. I am getting a reasonably healthy AHI score of around 4 most nights with only a couple of apnea events usually but this score is almost invariably inflated by the high occurence of hypopneas, and I know I can get the AHI a lot lower if I could just eliminate some of them. A few can be accounted for by mask leaks, but not all. I have experimented a bit with my pressures, but this doesn't seem to have made any difference. I'm at a loss, so I have posted a screenshot of last night's sleepyhead data. I realise it's time consuming to comb through it but I'd really appreciate if it if anyone could take a look and see if anything jumps off the page. Or maybe I shouldn't even be worried about these events? Thanks everyone

RE: Still getting high Hypopneas
Can you post a shot showing "Details", and graphs ... pressure, snore, flow limitation

Is this what you mean Zonk?

Hi Andy,

I think this is what Zonk has in mind. Note which graphs are showing -- these are the most helpful for us to see. (Drag graphs in SleepyHead so they'll all appear in one screenshot like this example.)

Are you using EPR? If yes then At what level (1,2 or 3)?

Kaiasgram I can't get everything to appear in one window even by changing my screen resolution. How did you do that?

I think I've included everything across the two screenshots though

Hi AshSF

No I'm not currently using EPR

RE: Still getting high Hypopneas
In SleepyHead you can grab and drag graphs into the position you want them. You can also shrink the height of graphs by positioning your cursor on the horizontal line of a graph and 'pull down' the ceiling of that graph. I shrink my event flag (top) graph, and since I don't really have significant leaks or snores I shrink those down too, in order to fit all the graphs in one screenshot.

If you're having trouble you can post your graphs in two separate screenshots -- but it's nicer if we can see them all in one shot so we can look at correlations between pressure and say, flow limitations or snores, all at the same point in time.

RE: Still getting high Hypopneas
Thanks, that's helpful. Interesting -- your pressure never hit the Max, and the 95% number means that your pressure was at or below 12.70 for 95% of the night. So if that was my SH report I think I would increase the Min pressure a little and see if the Flow limitations and hypopneas start to decrease.

Yeah I did try that already but didn't see any improvement. It may not have been enough. And as you say, the upper pressure isn't being hit, so...hmm....I'm still a bit mystified by it.
