Central/Open Airway Apnea while starting to sleep?

Having severe trouble sleeping today. Have normally been down in the 2-3 apnea / hr range the last few weeks. Suddenly tonight I have trouble sleeping and over just a short period of time I'm up over 20 apnea/hr...nearly all of it open airway/central according to report. It felt like nights before I was even diagnosed and started CPAP. Haven't been over 20 events/hr for over a year.

My machine always starts at pressure of 4 and ramps up usually 2-3 hrs into the night. During times tonight you'll see it was at pressure = 4.

Are these true apneas or just trouble getting to sleep? Having trouble getting call back from Doctor this week to schedule my normal check in and now really wondering if I need to find someone else to check out these apneas.

Would higher starting pressure than 4 help prevent them while I'm starting to sleep?

Attachments show 5 minute increments though the same patterns continued for 40 minutes before I got out of bed. Apneas totaled 10 minutes (25% of total time).

You have zoomed in way too close and we can't see the flow rate or breaths that happened just prior to the onset of the flagged centrals but I suspect from what you say is that these are awake breathing irregularities getting flagged by mistake.

I suspect they are a symptom of the poor sleep and not the cause of the poor sleep.

More pressure doesn't ever fix central apneas.

Just curious: do you feel at all starved for air when the pressure is at 4?
