Tale of Two Masks: The Good and the Bad

[Crimson Nape]

Looking at your charts on this thread, I would say that you might have been having a bad night and just happened to be wearing that mask. Some of your charts look like a pressure roller coaster, as if you might be tossing and turning. Do you have access to a camera with night vision to look at this possibility?

Before posting that chart I made sure the AHI were "typical" for both a nasal cushion night (<1 AHI) and an FFM night (2.5 to 3 AHI). It was just handy that I used both mask types on the same night. 

My wife, the all-time lightest sleeper in the history of womankind, would know if I tossed and turned a lot. "Trapped" by my CPAP set-up, collar and flat pillow, I sleep on my back almost all night, but in the last hour or so before waking, the old "side sleeper" in me tries to roll onto my side, whereupon leaks begin to drive me bats until I get up.
