This link will show an example of a night's sleep with meds onboard: Losartan, muscle relaxer, nerve pain med, double dose of acid reducer, and an anti anxiety med. Upon waking: No aerophagia, state of groggy for 1 hour,
blood pressure 171/95. Current state: Feeling more rested, groggy down by applying caffeine. Various pains down to level 1 (that will change shortly). Cognitive function impaired.
That sounds like the BP is not very well controlled. What does your PB usually run?
I think the meds allowed for a continuous 8 hours of sleep. While a bit wobbly, I am up and at em, trying to hard to get some things done for a change. The change in AHI is impressive on this report.
What the heck was happening between 1:00AM and 3:00AM Alabama time last night?
Here is a slightly zoomed in shot of your data (time stamps in the screen shot are EDT since I'm in Buffalo, NY.):

Lots of events, lots of flow limitations, and lots of snoring are all being scored. And the machine can't raise the pressure any more in an attempt to "normalize" the breathing since you've capped the max pressure at 9cm.
But the big question is:
Were you sound asleep during this period? Or were you dozing and going in and out of sleep during this period?
I ask because you also write:
Beginning sleep position: left side to left side with rotation towards being belly down. Other positions acquired during sleep: supine. Restless attempts at sleep positions are a continuous roll from left to right side, supine, on stomach then get up and forget trying to sleep.
Furthermore, if we zoom in further on your data, we see this right at the beginning of that horrible stretch. (The timestamps in the screen shot are for my local Eastern Time Zone, since I'm in Buffalo.)

Now there are several things I want to point out about this part of your data:
1) You obviously had turned the machine off and back on just before this stretch starts. When your machine starts, it activates a ramp and your pressure ramps up from 4cm to your current minimum setting of 5cm. And your machine does not record events during the ramp period. That's why those things that look like apneas/hypopneas in this stretch have not been flagged as apneas/hypopneas.
2) Because we know you were awake right at the beginning of this stretch, it's reasonable to assume that this breathing pattern right at the start of this stretch is what's often referred to around here as
sleep-wake-junk breathing, or SWJ for short. The transition to sleep is not always smooth and sometimes that is reflected in the breathing: The handoff of control of breathing from the voluntary to automatic (involuntary) nervous systems sometimes involves glitches that can look like apneas. On an in-lab sleep test, the tech has the EEG data and the data from the belts to properly figure out if ragged breathing right as you are trying to go to sleep is actually sleep disrupted breathing or just a normal variation on transition to sleep breathing. And if it's just a normal variation on transition to sleep breathing, these kinds of stretches of "not breathing" don't get scored as a sleep disordered breathing event--i.e. a hypopnea or an apnea.
3) The problem here is that the SWJ-type breathing pattern that we see right after you turn the machine on
continues for a very, very long time--as in it continues for the next 2 hours pretty much non-stop. You never really transition to a normal, regular sleep breathing pattern during this whole 2 hour time period where the huge number of OAs are scored. And what happens after the ramp period is over? The machine starts scoring events every few minutes because the machine's programming now assumes you are in fact asleep and those stretches where your respiration is significantly reduced now match the machine's criteria for being scored as events. But the machine has no EEG data, so it cannot tell when you finally fall asleep. So, as I said before, the question becomes:
Were you sound asleep during most of this 2-hour period? Or were you dozing in and out of sleep during this 2-hour period?
4) Notably right around 3:00 AM Alabama time (4:00 AM on the screen shot since I'm in Buffalo, NY), your breathing
does settle down into normal, regular sleep breathing. And no events are being scored and the machine finally starts to lower the pressure. Here's what your
normal, regular sleep breathing looks like:

So we can definitely conclude that you were in fact sound asleep by 3:00 AM your time and that the machine's pressure was doing its job of preventing obstructive events from occurring.
