2 Part question:
1. Did the machine come set with what the respiratory therapists WANTED me to use? I.e they programmed it custom for me?
2. Assuming thats true, would restoring it to factory restore it back to that setting?
Did you ever have a sleep study, where the tech put you on cpap and mask, to figure out pressure needs?
If you didn't...no one has a clue what pressures you need and even if they did it doesn't mean they were correct.
Think about it...how would anyone even have the least little idea what pressure to use?
Most likely they just sent you a machine with factory defaults (or near defaults) and then hoped the machine itself would sort out the pressure needs and deal with things. That the most common thought for both doctors and DMEs and respiratory therapists when it comes to dispensing auto adjusting machines.
And hey....sometimes the defaults work well for some people so worth starting with and then adjusting later if there is a proven need.
A big problem with the defaults is that the very low starting pressure simply isn't comfortable and people feel air starved and can't sleep well because of feeling like they are suffocating. They won't suffocate but try telling the brain that fact.
The brain won't listen and it will try to keep its human awake so it can't suffocate.

Result...can't fall asleep.

From the AHI of 24 from my original test, can I assume that that AHI was from OA?
Yep. Safe assumption. Your machine is doing its job...preventing obstructive apnea events...extremely well.
Easily seen with the minimal number of OAs and hyponeas (those are obstructive in nature events).
The CAs/centrals are primarily false positives related to crappy sleep...and once we get you to sleeping more soundly those will go way down in numbers.
An occasional real central is normal and no big deal anyway. So don't think you won't ever see a real central because you will...centrals aren't problem unless present in large numbers (and you were for sure asleep) or they cause desats or in the case of sleep onset centrals they bounce you out of sleep repeatedly. I don't see that with your last night's results.
What I see is simply crappy sleep from probably external stimulus issues.
You had a bad night...it happens...we shrug our shoulders and move on.
You are new to all this stuff and people new to cpap tend to think everything wrong with sleep is apnea related and fixable by the machine and the cold hard fact of life is that nothing is further from the truth.
Last night was a "bad sleep" night...but not from apnea or airway issues....just a bad night in general and nothing we can do from the machine's stand point can fix the cause of the bad sleep last night.
Quit trying to micro analyze it....combination of just being new to cpap therapy causing the brain to be hyper sensitive and likely your worry about your dog is the cause of the bad sleep last night. It's water under the bridge....tonight will be better.
I may have to RISE but I refuse to SHINE.
