narrowing pressure ranges yields worsening results

On the first graph it actually hits the max during a spike at 6:25AM. I take it as long as the max is very brief and doesn't "stay there" and flatline like a maxed out CPU then there's no need to raise the limit?


Correct. If you notice the APAP responded after the OA and Hypopnea event, then came back down.
If the pressure stays at your max setting for a long time during the night, then that's an indication it wants to go higher, sometimes not in response to an apnea event but in response to snores and flow limitations.

You cannot evaluate any thing until your sleep quality improved and not sleeping without the machine
You'll need to figure it out, whether its comfort issues, such as mask doesn't feel right or comfortable,
too much or too little humidity and pressure relief

Noted. Is the opposite also true, in that if the APAP pressure never flatlines on the minimum, touching it only briefly before jumping up to a higher pressure, is that a sign that there is no reason (apart from initial comfort) to lower the minimum?

You can lower the minimum if your therapy warrants it, but it serves no purpose to have a minimum pressure set too far below the medium or 90% pressure, because the APAP will take longer to reach the pressure needed to open your airway.

My PR SystemOne does this "hunt and peck" thing, meaning it never a stays at my start pressure for any length of time. It will raise pressure approximately 1.5cm and then goes back down when nothing it detected, meaning no FL, RERAs, Snores that may indicate an upcoming apnea event.

It doesn't do this continuously, because I can see where is will go back to starting pressure and stay there for short periods of time, only to start its "hunt and peck" again.

I don't know for sure how ResMed APAP's work in that regard.

I agree with Zonk. You need to concentrate on whatever is causing you to not use the CPAP all night long. With incomplete nights of machine use there are a number of variables added that make what we see in the data very questionable. As an example, the CAs may be sleep-wake junk whether you feel that is true or not. If you removed the CAs, your graphs would look a lot better except for the leaks. What are the issues that keep you from using the CPAP all night long?

Best Regards,
