What am I missing? - Rcgop - 10-20-2016
Graph 1.
Took a nice mid-day nap. Best nap ever with good results.
Graph 2.
Went to bed about 9:30 and slept for the longest time to date. Best sleep too. Got up for bathroom break. (didn't think i was up that long but not the issue)
Went back to sleep and slept very good until around 4:00 in the morning. I woke up and was just laying there half awake and half asleep. All the time thinking I was going to have the best night of my life. OBTW, night before was a zero night.
Graph 3.
About 4:00 all hell breaks loose. Leaks are under control, Flow limits are reasonable. Snores do not exist (after 4:00) I know it might just be sleep/awake junk but my O2 level dropped to at least 86%. I know this because I have an Oximeter and put it on my finger to see if I could catch it just right and I caught that. It could have been lower but I have to wake up to read it.
Is there something I can tweak or should I just start getting up at 4:00?
Am I missing something?

First let me say I have not gone back and looked at any other threads, so I do not know your history.
Sleep/wake junk can effect O2 levels-if you stop breathing, your O2 will go down, regardless of the reason. it's just that CPAP does not effect sleep/wake junk so when talking about CPAP we ignore sleep/wake junk
For anything else I will let those who know more history comment

Looks like sleep/wake junk to me. I would ignore it. When you are waking up or awake or in that very light in and out sleep, it is normal to have a lot of apneic events. I used to have the same kind of stuff all of the time. Made me wonder how some people could possibly get a zero AHI. I did notice that their flow rate looked more consistent and even than mine. I stopped thinking about it and over time guess what happened. My flow rate got more even and consistent and, if I decided to lie in bed and vegetate for an hour after awakening, I no longer got a bunch of apneic events during that time.
I do not know for sure what changed. I do know that previously when I would lie down to go to sleep I would consciously breathe more deeply than normal and it almost seems like that carried through on and off during the whole night. At the point where I think this started changing, I decided to try to emulate my "asleep" breathing (a little quicker and shallower) and I am still doing that. I think that started the change to my whole night's breathing. That and I think that my mind decided that it could trust the machine to allow it to breathe all night long without interference.
The shorter version is; don't worry about the sleep/wake junk, it is not meaningful

Yeah, if you are awake, or in the gap between sleep and awake, the machine and you can have disagreements. I've noticed it with mine as well. If I wake up and can't decide if I am going to fall back asleep or get up, I reach over, turn off the machine for a few seconds, and turn it back on. If I do fall asleep, all is well. If I don't, then I can remove that data from the SH results.
I do the same thing if I have trouble falling asleep. If I lay there and can't fall asleep, I reach over and turn off/on the machine just so I know to remove that data. Even if no events happen, time is as much a part of the AHI as events are.

Nooo. We aren't number driven at all.

How do you remove the data?

Having made my living dealing with numbers, how can I ignore them.
RE: What am I missing? - PaytonA - 10-20-2016
What makes you think that you are the only one who has made his living dealing with numbers? Besides numbers are easy to ignore when you finally find out that, in general, they are only somewhat meaningful.
If you do what Paula said, when you wake up and you just want to lounge for a while in bed, turn your CPAP off momentarily and then turn it back on. That will give you a new session that you can turn off in Sleepyhead. Go to the daily tab and the details tab on the left side in Sleepyhead. Scroll down to the session information. There you will find the sessions for this day. You can turn any session off by clicking on the little green switch which should then move to red. Any events in the session that you turned off will be turned off too

Nice feature. Thanks PaytonA and Paula02.

As I said before, I am a numbers guy. And since trends are important here, I made a spreadsheet to determine my 90% pressure. Going back, using the process above, I re-did the sheet. Adding a least square trend line, I can be reasonably assured my 90% pressure (for October) is between 8 and 9. I am going to say 8.5.
Starting in November, I will probably start moving my min closer to 7 and my max down closer 9.5-10.
