Leifurh, As for interpreting OSCAR Reports, CPAPFriend is a forum member who has posted several very helpful YT videos. Try these to start with.

Try hydrating first thing in the morning with a tall glass of water, follow up with hydration early and throughout the day, start restricting fluid intake after 1900 to minimize the 0345 wake up for a bathroom pee break.

Two points I forgot to address. First, will an AirSense 10 allow a 4 cm spread between minimum and maximum pressure? I thought 3 cm. was the maximum difference supported. Second, how do I share a whole OSCAR "daily" log? The only guidance I have seen addresses screen shots - which inherently can't do the entire report.
RE: Low SPO2 despite CPAP use - UnicornRider - 07-22-2024
EPR is limited to 3 cmH2O.
Min and Max pressures can differ any where from 0.00 cmH2O to ~16 cmH2O
You will have to take separate screenshots, The YT videos will show you how to pin graphs and arrange graphs for requested views.

As for "ramp", all I know is that before falling asleep I hardly feel any pressure. I thought that was "ramp" in action.
As for sleeping positions, I never sleep on my back, I alternate between the two sides.

flow limit (FL yes) means your airway is restricted. the machine responds to flow limits by raising pressure which should open your airway and reduce the flow limits. sleeping on your back could have explained why yours seem to go up when the machine raises pressure. but that's clearly not the case here.
ramp keeps the pressure low for a set amount of time or until you fall asleep. it's usually better to leave it off unless you really need it. says ramp off in the left column.
edit: you can read more about FLs in the oscar guide
