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?

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.

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.
