Note the Clusters of Obstructive events. Clusters are a tell of what is most likely a form of positional apnea. Try one pillow vs two or latter, less firm pillows. Why? The most likely cause is you are tucking your chin into your chest. Try it, I'd bet you find it more difficult to breathe that way. The goal is to remove that kink in that hose we call an airway. You may need to use a soft cervical collar, see the link in my signature. This typically is not fixed with pressure and most likely is why your pressure rises to the max that you have set. Flow Limits, yours are all high, will increase pressure as well OA and H events. Positional apnea will cause flow limits.
There is no official medical parameter but we have observed the FL 95.5% stat of 0.10 or higher should be addressed, Preferably down to 0.02-0.03 or lower if possible. EPR=3 is what will help this AFTER you manage the Positional Apnea.
