Plmnb's Never Ending OSA Journey (Data)

Yes, ApneaQuestions, this helps.

So, according to the sleep lab report I DID have real, confirmed Central Apnea events, correct?

If this is really the case, then I DO have MIXED APNEA?  Even if it wasn't a ton of those?

I think you might be mixing your terminology

"Mixed Apnea" describes a single apnea event that starts off looking like one thing and ends up looking like the other

"Complex Sleep Apnea" describes your diagnosis over the whole night.

and here: https://www.medscape.com/answers/295807-...ixed-apnea

BTW I edited my previous post several times so read it one more time

Oy vey.  This is so confusing ApneaQuestions.  But you are helping me to understand.  So, what I now mean to ask is, is it possible that I might have "Complex Sleep Apnea" even though I have so few central apneas compared to my other apneas as per my sleep study?

I don't want to make a mountain out of a mole hill if not important to bring up to the drs.  But with how difficult it has been to get right with this situation I am trying to leave no stone unturned.  I have copied and am trying to simplify and organize the information for my appointments.  Should I leave out mention of the concern I have about the centrals?

Thanks!

Reading links posted by ApneaQuestions.  According to what I am reading Complex Apnea is determined after you start therapy with the machines. 2. Definition

Complex sleep apnea syndrome (CompSAS) is a form of sleep disordered breathing in which central apneas persist or emerge when obstructive events have disappeared with PAP therapy.


If this is so, how come I have any Centrals reported without the machine?

[ApneaQuestions]

...., is it possible that I might have "Complex Sleep Apnea".....

Well I see why you are asking the question... but here is where the arbitrary thresholds creep in.

Remember... if you stop breathing for 9.9999 seconds ... you did NOT have an "apnea"
but if you stopped for 10.00001 seconds... you DID

The definition of "Complex Sleep Apnea" has these kind of thresholds too.
Take a look at the link I mentioned earlier showing definitions or google for a quicker answer

Notice the talk about 5 per hour, notice also the talk about being measured during a PAP titration to clear up the obstructives.
If you only got 6 in a whole night... then that's not likely to be over 5 per hour.


The better question to ask yourself might be.....
Once I've done everything to optimize my PAP treatment using the best device I can get.... can we see any residual Central Apneas that may warrant further thought and a possible move to (say) an ASV machine? 

My best guess is... I doubt it.  Let's try it and see.
It seems like you may have improvements with the new BIPAP machine.
Once you've got some solid data using that machine for a while, see how things are looking then.

Make sense?

You are possibly mixing terminology again ;-)

In an untitrated study you can still MEASURE and DETECT Centrals.  That's exactly what they did.

But you can't officially use the magic phrase "Complex Sleep Apnea" unless and until you follow the strict definition of that expression.
The term seems to be reserved for the findings during a titration study not in an untitrated sleep study.

Do you see the subtle distinction?

[Plmnb]

Lol, sigh. How do you all keep this information straight? It seems so technical and complicated. So many nuances and stuff. I suppose helping people so much is one way. Do some of the helpful board members have training in the field?

I’m not used to sitting back and taking it easy so this wait for the next couple of appointments is gonna be tough. Be prepared for many more questions.

By the way, you are obviously working hard and doing a great job of figuring this stuff out.
You probably are not reading my thread because you are (rightly so) wanting to get your own situation sorted.

However I recently put some "easy to understand" posts on my thread to document stuff I learn as I learn it.

This post (and the subsequent 2 posts) might be useful for you.

Using the terminology on that post, you have finally "moved up blue arrow number 2" from PAP to BIPAP.
Your questions about Centrals are a little premature for the time being and are more related to "moving up blue arrow number 3" to ASV

Those last two sentences will make more sense after you've looked at the post.

I don't think you'll end up needing to make that move to ASV.
We'll soon find out after you've been using the BIPAP for a while and tweaked the best settings.

 Thanks ApneaQuestions.  I will go read your links right now.

You have very few CAs on your OSCAR charts and only 6 central apneas with 2 mixed apneas on that report. You don't have complex apnea based off what you have posted.
