The large leak territory is shaded in light grey.
Sleepyhead looks equally bad:
It strikes me that on both charts when the large leak was at it's zenith around 130 L/min, my respiration got very shallow. Is this normal and to be expected? It could have happened before and I just never noticed. As a word of explanation, what no doubt happened here is that I had jaw drop right out of the bottom of my mask and it became dislodged from my face. This mask is the Quattro Air and is probably my favorite mask for a lot of reasons. Normally it throws good numbers; occasionally however it will ride up on my face and I'll awaken with the bottom of the mask in between my upper and lower teeth, and I'm sure that's what happened here.
I also notice that when the leak was at it's max the difference between the purple and green leak lines in SH approach 100 L/min. I thought that the difference between the two lines roughly equaled the built in vent rate for the mask itself which is around 45 L/min. Does everything just go out the window with a leak this big?
As an aside it's interesting that with all this leaking my AHI was still 1.24. Yes, I know that it is thought when leaks this large go on for so long AHI numbers are deemed unreliable, but normally when I have a bad leak night my AHI number skyrockets as well.
