That looks pretty nasty, but I'm not sure the CA and periodic breathing are legit. That might just be a gnarly cluster of obstructive events with deeper recovery breaths in between each one. Might be easier to tell if you zoom in a little closer.
Did you ditch flex and increase pressure in CPAP mode, or at least up the minimum in APAP to 10 last night? How did it go?

I increased the min to 10 and max to 14. I had a case of insomnia last night, so I wasn't able to sleep at all. Hopefully I'll be able to sleep tonight and see if there were any improvements. I attached some zoomed in screenshots.

Looks like you have an unusual partial obstruction pattern in the majority of your breaths in this time period. A partial obstruction commonly presents as a sharp peak in the inspiration flow with an early reversal followed by either another peak or a plateau. Yours technically look like this, but it's unusual because the second peak is taller. Normally, the body gets some air, encounters an obstruction, puts a little more oomph into the breath to fill the lungs, and then exhales. You are encountering resistance and then taking in a big breath after breaking through it. Might be because it's apnea recovery breathing, but I definitely think you have airway resistance at the root of these events.
I always had plateaus before surgery (now afterwards I haven't seen any flow data yet), but different types of obstruction cause different shaped flows. Yours might look a little different as well because I believe the Phillips machines record at 5 Hz and ResMed machines poll and record flow data at 25 Hz.
