This image shows detail from the Sleepyhead flow rate graph for 3 CA events that I had a couple nights ago. There's nothing remarkable about there being 3 events.
I can't help wonder, when looking at these three graphs, if these are really all the same type of event.
The top one, I suspect, is from me rolling over in my sleep given the steady breathing beforehand, then a moment of chaotic breathing, then settling right back down to steady breathing. It might also have been from coughing in my sleep.
The second one, from a couple hours later into the night, looks like a typical obstructive event to me - definitely looks different than the first.
The third, based on what I've interpreted from some of the posts I've read on this forum, looks like the start of a section of periodic breathing, but it lasts for less than 60 seconds, so I'm not concerned about it.
In all three cases, the pressure was at or near my minimum of 9.6 EPAP/13.6 IPAP.
I'm curious about tiny differences like this because, while I typically have an AHI of below 1 (it was 0.41 on this night), I'm still tired most days - but some are better than others so I'm looking for insight into what's different on those nights when I wake up feeling more rested.
Thoughts? Barking up the wrong tree? Seeing information where there's really just noise?
