The pressure spikes around 8 AM are just the routine test pressure probes where every so often, depending on what the machine is sensing in general, it increases the pressure 1.5 cm and tests the "waters" so to speak. Just normal function that happens to look more remarkable due to the scale of the graphs here. On Encore they would be tiny. They aren't as rapid as it initially looks like either...in reality the increase is much more subtle.
See this thread for examples that are a little easier to see.

I need to go back and look at some of the initial reports where the AHI wasn't so bad.
Given that the AHI seems to have gotten worse instead of better and it seems to be mainly hyponeas and the machine doesn't want to kill them...I am wondering if they are central in nature and if that is the case then I wouldn't be increasing the pressure...I would be backing way up and starting lower at maybe a fixed pressure.
Give me a bit of time to go back and look at the older reports where I was wondering where the titration study came up with RX of 13 and the machine didn't want to go there. I need to refresh my memory a bit.
Edit: Okay I went back and refreshed my memory and the first reports in terms of AHI were a lot better than what we are seeing now and the leaks were better too.
Things have gotten worse with the pressure increases and not better in terms of AHI numbers and that along with the hyponeas in abundance (and I assume you weren't awake during that time period) and the machine not wanting to increase the pressure makes me wonder if they hyponeas are central in nature or maybe half and half or something.
I would back way up if it were me and try 8 or 9 cm with no range or teeny tiny range.
I suppose we could try apap with min of 13 and max of 15 or 16 just to see what the machine wants to do but if those are centrals related to pressure it won't help and may make them worse.
