Thanks. I won’t be concerned about that issue. However, I noticed that the pressure increased at the same time and I had a leak shortly after. Did the machine increase pressure because a change in breathing, or am I reading too much into this?

The machine will increase the pressure because it thinks it needs more pressure to keep the airway from collapsing.
Obstructive apneas, hyponeas, snore or flow limitations....these are what drive the pressure up.

Leaks don't drive the pressure up. The machine will NOT increase the pressure itself in an effort to fix a leak.
Now sometimes the more pressure the machine wants to gives in an effort to prevent airway collapses will actually cause a leak and it might be so close together in timing that it looks like the machine is increasing the pressure trying to fix a leak but it isn't.

If you look at your last zoomed in on image where you wondered about the flow rate after 04:15 ....look down and see the little bumps in the flow limitation graph....those are why the pressure went up a bit and stayed up a bit.
That increased leak line about the same time....probably mask movement since the leak actually started about 6 minutes prior to the increase in pressure.

I'm back to see if someone could comment on my last night's OSCAR data. I feel like I had good night's sleep, but I noticed I had some RERA's that seem to line up with elevated flow limitations. Am I reading this correctly and is there an adjustment that could be made to address it. Thanks again for all your help.
