Is this Cheyne-Stokes?

That doesn't look like Cheyne-Stokes to me. What it looks like is that after you have an apnea event, you breathe deeper for the first few breaths afterwards as you "gasp for air". If you look at the Wikipedia article, Cheyne-Stokes breathing has a much slower breathing depth on recovery. The breathing oscillations are almost circular in shape. Yours, on the other hand, show much more of a "decay" pattern as an initial high flow rate slows down and another apnea event happens.

I see... Maybe it's another variation of periodic breathing? All those successive central apneas don't look good to me
