How many CA's are normal to have in a night? I have my auto pressure set to 10/17 and it seems to be controlling my apneas pretty well. My AHI was 2 last night. When I look at my sleepyhead report it is showing most of my events are centrals. When I look at the times that I am having these, I know that I am asleep. I don't appear to wake up from most of these events. Since it's only 5-10 a night, is it normal to have these? I currently have my flex set to 3 to make breathing comfortable. Since I am having the best sleep that I've had in probably 10 years, I really don't want to change anything unless I have to.

Yes...it's normal to have a few centrals during the night and have them be the real deal.
Like it's normal to have what is called a sleep onset central when we transition to sleep.
We normally have more than one transition to sleep besides the obvious one at the beginning of the night.
It's normal to wake after a REM cycle (we may or may not remember awakening) and we fall back asleep so another opportunity for a sleep onset central. We can have several REM cycles...and we can also wake up for any number of reasons.

It's also likely that some of the "centrals" may not be real but instead might be a turning over in bed hold your breath central.

So it's possible that some of yours are real and some aren't real.
Doesn't really matter though...you aren't having enough of them to be a problem even if every one of them was real.

Most doctors won't worry about the number of centrals unless they are seeing at least 5 per hour average consistently throughout the night and every night.

So...since you are sleeping good and feeling good with current settings...I wouldn't change anything and I wouldn't worry about the small number of centrals you are seeing. It's normal to see a few here and there...not a big deal.

Is there any way to recognize these onset/turnover centrals graphically (on Sleephead)? Do they have identifiable wave forms?

Sometimes we can spot awake/post arousal central vs asleep central based on the flow rate but it's not always black and white.

Jason has a video explaining what to look for

Are these real centrals or 'junk' centrals...they seem to be preceded by an large inhalation?

They do look a bit "iffy" to me with the inhalation just prior to the cessation of breathing. Couple of them more so than the other but can't really see the flow pattern that preceded the event all that well to get a good feel for was it asleep breathing or a turn over in bed pause thing.
Sometimes looking at this stuff and determining real or not is easy and sometimes it's not so easy.
I like to try to see more of the flow pattern than what was shown here to help me out because sometimes I need all the help I can get deciding if real or awake or whatever.

These are OA flags...pretty sure they are real due to the nice normal respiration pattern preceding them.
Image

This one isn't zoomed in as close but I think post arousal...SWJ...the irregularity in breathing just prior to the flag is very easily seen. So awake or semi awake that may or may not be remembered.
Image

I don't seem to have a good example of a central handy (I don't see many of them) but if I spot one on my report and I don't forget I will come back and post it for you to see. I don't have the time to go digging right now.
