Your SleepyHead charts show your treated central apnea index to be zero. You have a lot of untreated hypopnea. One easy way of seeing whether Centrals are an actual issue would be to switch to Spontaneous (S) mode and see what happens to the CA index.
One thing that stands out to me, since I look at respiratory data primarily, is that your median tidal volumes and minute volumes are very low. That could be due to all those untreated hypopnea. The answer to that is generally more IPAP/Pressure Support, but it has to be done carefully.
What is your current backup rate set as? And, on the machine itself, what does it say your Percent Triggered Breaths % is on the report screen after a night of therapy?
Your median respiratory rate is rather low, so if your natural RR while asleep is bumping against the backup rate a lot while you sleep, it can cause you to “fight the machine” and unwanted arousals may happen as a result.
