Not always worth trying to squeeze out a bit more sleep

Sometimes it's just not worth trying to squeeze out a bit more sleep in the morning.

Here's an overview of my data from the night of Aug. 9:




You'll notice things look pretty decent prior to that wake at around 9:00 AM. At that point I decided
I was still somewhat ssleepy and not ready to get up. So I turned Kaa back on and this is a close-up of the mess that resulted:






Wow! 12 events in about 30 minutes. And periodic breathing. And only one labeled as a CA.

My best guess? I spent most of those 30 minutes in WAKE or transitioning between WAKE and Stage 1 because I remember some tossing and turning in an attempt to get comfortable. And I remember a lot of "thinking/daydreaming", but I also remember feeling like I'd dropped off to sleep for a few minutes now and then. (And I wasn't wearing the zeo last night.)

I've concluded that I might as well have gotten up instead of trying to squeeze out a few more zzzzzs: Not only does this half hour look ugly, but when I did get out of bed it was because I was feeling the aerophagia starting to build up in the ol' tummy.

Anybody want to offer opinions?

Am I likely awake during most of these events? And if so, why are they labeled as OAs instead of CAs?

Final note: That last half hour is very atypical of my data these days. The rest of the night is pretty typical of most of my data. You throw out that last 30 minute session and the overnight AHI goes from 3.30 down to 1.32. And before lying back down and turning Kaa back on at 9:00ish, I wasn't feeling any aerophagia either. *sigh*

Back in May I had a night where I woke up around 1 AM really, really sick to my stomach. I lay there tossing and turning and trying to decide if I needed to go throw up but I stayed in bed with mask and machine on. I did lay there and was really miserable though. It took almost an hour before things subsided and I finally went back to sleep. I am 99.99% sure I was awake tossing and turning and breathing like we do when we are nauseated and fighting it.

I had a cluster pretty much like your 30 minute cluster.
18 events in about 45 minutes...11 Centrals and 7 obstructives.

I have also had little 30 minute clusters right before I get up and I have been laying there thinking about getting up but not really wanting to. Had both centrals and obstructive events.

When I look at them up close I can't really see much difference between the flagged centrals and obstructives.
I think that the machine just makes a mistake and thinks that some "centrals" are obstructives. I don't know why though.

I have seen this happen fairly often when I lay in bed cussing the dog or bird for waking me up and like you, trying to get just a little more sleep but can't really go back to sleep. Since I know that the machine can mistake awake irregular breathing for some sort of event that is why I always question similar clusters when I see fragmented sleep especially if there are periods of nothing before and after.

I think you are probably correct. Awake or maybe semi awake cluster of events because the machine got fooled.

I sometimes, after awakening in the morning, lie in bed half dozing for a half an hour or hour. I get similar disturbance patterns to what you posted. They consist of various apneas and even an occasion PB episode. They wreck my usual AHI < 2 daily averages, but I just figure "So what?". I can easily go into Sleepyhead and drop out the 'dozing segments' to accurately calculate my true sleep AHI. Sometimes it's just fun to lay in bed for an extra half hour and watch the colorful visions unfold.

Here's a related link to the phenomena of lucid dreaming, ie, the hypnagogic state of sleep:

IMO I think that you were "half" asleep.... very lightly dozing here and there. Instead of relaxing and enjoying the extra time in bed, you were restless and subconsciously concerned about what the data might look like if you stayed in bed.

I'll agree I was only half asleep and restless due to some comfort issues.

But the data was NOT what was on my mind. Aerophagia was an issue. And I was still tired from the night before: We'd driven from Buffalo to NoVA and got into my brother's house around 2:00AM. So I thought I'd let myself have a bit more time to sleep after waking up at what's become my default wake up time of about 9:00.

Forgot you mentioned Aerophagia... sorry about that. I'm sure it was a problem but I do think the restlessness manifested itself in many directions.

At any rate, I'm sure tonight will be much better... even if you decide to sleep in a bit.
