Not anywhere near Cheyne-Stokes respiration in terms of the minimums, but a clearly repeated pattern through much of the night. My machine scores zero central apneas. I am wondering about this as my AHI is usually well below 1 and my RDI below 2 and I still feel like I need more sleep when I wake up. I was thinking maybe UARS but this is a new idea.
I reviewed my own graphs and did some searching on periodic breathing, and I'm pretty sure I really don't understand what is being described, but I did have an idea - have you tried measuring your blood oxygen levels at night? If the periodic breathing you're describing is the reason you feel you need more sleep, then maybe pulse-oximetry would help show that there is a problem there.
