Very Strange OSCAR Results

[upsman]

In my entire 10+ years of PAP therapy, I've never had results like this before. 
I must admit that last night was a "fitful" sleep session where I remember quite a few arousals. Probably 5 occasions. 
I'm guessing that the clumps of centrals would probably correspond to the times I woke up, but it just looks very odd and extremely unusual for me. 
The second screenshot is a typical sleep session for me.

You got into some "periodic breathing," where you do some heavier breathing, which blows off some CO2, which reduces your drive to breathe, which results in a CA, which is followed by heavier recovery breathing, and on and on. I bet you're right that this is connected with your fitful sleep. When you experience an arousal from sleep, this often involves heavier breathing, which can set off a periodic breathing cycle.

Just keep an eye on it. If you see this every now and again, I wouldn't worry about it if I were you. If it gets to be a regular thing, you might turn off your EPR to see whether that helps.

Thanks, Dormeo.
That’s pretty much what I was thinking too. 

I’ll watch things and hopefully this just a one-off situation.
