Re: Centrals been on the rise a bit.. Lower pressure?

Yeah, it would have been interesting to see where the machine wanted to go in response to that cluster of OAs.
Maybe you needed a little more pressure for some reason (most common reasons are of course REM stage sleep or supine sleeping or both....or maybe aliens )
You get the same speech I tend to give everyone. If pressure changes don't seem to disrupt sleep then might as well let the machine do what it is designed to do. That's why I do what I do even with my bilevel machine. Sometimes I just need a little more pressure and sometimes a LOT more pressure.
The other alternative is a little more straight cpap pressure to see if it makes any difference overall. We just don't know what it would have taken to prevent that cluster. Might have been just a little like 0.5 to 1.0 more straight cpap pressure or it might have been one of those times where you needed a LOT more. If you think that your overall quality of sleep is maybe better in cpap mode. Might want to think about just a little more cpap mode pressure and see how things go.
It's impossible to anticipate every possible scenario though. We simply don't know ahead of time what is going to happen during the night. So sometimes crap happens despite all our best intentions and preventative measures. I still will occasionally get little clusters like that despite having a wide open range to 20 cm...so that tells me that sometimes I probably need a little more minimum (in my case EPAP now on the bilevel machine). Since I sleep decently and feel decently...I don't worry about those random times where the clusters pop up like that where maybe I could have used a bit more pressure. To eliminate every little thing I would need to use more pressure all the time and that would mean using a lot more pressure all night and I just don't want to do that for maybe 15 minutes of needing a lot more. Plus most nights...don't need any extra pressure. I learned a long time ago that I really couldn't tell any difference in how I felt each day between AHI of 0.5 and AHI of 3.0 nights.
