Irregular breathing causes transitional sleep apnea?

I'm experiencing the same symptoms described on this thread. Basically, my breathing becomes shallower and more labored as I'm falling asleep. Eventually when I doze off, my breathing stops completely. Immediately my body wakes me up with the need to "manually" take a breath.

Last night I hooked up my CPAP and I tried to document what I was feeling with real data.

This is my "awake" breathing, while I'm comfy settled in bed.

And this is my breathing a few minutes later, as it becomes more labored. You can even see the pauses that wake me up:

Does anybody have any idea what this could be? Is my diaphragm or some nerves damaged?

What kind of CPAP do you have? Are you using EPR (ResMed) or Flex (DreamStation)? The pressure seems to be on the low side. You might find some benefit in a higher pressure and using EPR if you are not already.

This is from a ResMed Airsense with EPR. I think between EPAP: 4 and IPAP: 8. How much higher do you think it should go? Thanks!

It would be helpful to see your mask pressure chart as well. I would try setting Your minimum pressure at 8 cm, with a ramp start pressure of 8 cm also. I like to use the Ramp Time set to Auto. And set the EPR to 3 cm (that is the max) and also to Full Time. That will start you out with an IPAP of 8 cm, and EPAP of 5 cm. When the machine detects you are asleep it will switch to auto and increase pressure as needed above 8 cm.
