flow rate irregularities during REM

[Morbius]

SWJ is Sleep Wake Junk (a term I invented), used to describe single channel data that appears to contaminated by Wake, Movement, Earthquake, etc.

Oh right, now I remember.

I got another one-- "Train Wreck Sleep Architecture".

Based on what has been stated so far, IMO you don't have an "SDB" problem, you got a "S" problem.

OMT just so I can get my post count up.

Look at this and tell me where you would get the most bang out of your buck:

That's a good one. Gotta remember that. TWSA

Sort of like this guy below who didn't even have OSA (per in lab sleep study AHI 1 ish) but had really, really crappy sleep.
He got rather annoyed at me because I couldn't pull some magical machine settings out of my bag of tricks to fix his problem and wanted him to at least consider the Wellbutrin/or similar med (I forget exactly what he was on) as a contributing factor to the crappy sleep.


FWIW to the OP here....I see variances in flow rate similar to yours pretty much every night. It might be the phasic REM like Morbius talks about or it might just be from some tossing and turning a lot since I do have some pain issues causing some sleep problems.
Heck, might even be dream related changes in breathing.

Just to pick up on the question about FLs and flex. When pressure increases at the beginning of inhalation, that little boost can prevent FL in some cases, reducing the effort and potential disruption that FLs can (in some cases) cause.

You might try A-flex, which might reduce the feeling that you're being hustled too fast into your next breath.

Your O2 levels are within the normal range,well above what's considered low.

Your device appears to be treating your apnea very well. Perhaps increasing your pressure, *might* optimise it a bit more. You had 3 flagged Flow Limitations and given the last one occured at the end of the session it's probably not real.

You're not allowing your device to increase pressure should it need to. Why?

Increase your maximum pressure, but I don't think whatever problems your having will be fixed by changing your CPAP settings.

I could try it I suppose, but in the past i felt like the high pressure was waking me up.

[jcpruitt89]

The top of the curves look like I'm getting flow limitations.

So how many? Your software says you got 2. Isolated single FLs, if they do not disturb sleep continuity (i.e., generate an arousal)(and you sorta hafta guess if all you got is a flow waveform) are totally benign. IMO you're trying to fix something that doesn't need fixing.

I guess I wasn't really specific, I have a significant amount of RERA's in addition to the FL's. Based on my stats I average around 1.5-2 RERA per hour and even with pressure changes this number doesn't change. I just don't feel rested even if I don't wake up which I often do.

This was probably the best ahi I've had in probably 3 months but RERA is the highest. So maybe RERA? So are these Ratty Wave forms normal? Not every wave form dip triggers an event but a pretty large amount of all the "REM" waves have inspiratory dips to some degree. How do you decide when it is a problem?

There could be some truth to that in there. I do have mild OSA per the take home sleep study but it wasn't until I discontinued TRT that I could no longer sleep through the night. Back on TRT briefly to see if that was the ultimate cause or not. I sleep better but I'm still not relieved. I just don't feel rested ready to start the day ever. Just trying to find anything that stands in my way.

Oh, I'm sorry.

In that case IMO you're trying to fix something that doesn't need fixing.

No. It's Variable Breathing at 45%.

IMO a real NPSG is warranted because I seriously doubt your AHI is even 6.xx (done with a home study).

And I say this because you're spending a lot of time and money on SOMETHING THAT DOESN'T NEED FIXING!!

And that needs to proven to you.

Put up a FatBit graph.

Pugsy gave you good advice in your initial posts.

Yeah, I'd go with taking horrible sleep and then trying to wear a CPAP mask at 15mH2O.

So variable breathing is indicative of insomnia or poor sleep and that's what you think I should address? By saying "doesn't need fixing" what do you mean? My sleep lab titration was 13cm and you say you believe a setting of 15cm is contributing to my problem. What you should I do with the CPAP?

Something is waking you up, and you're blaming it on high pressure.

Since you were asleep, you have no way of knowing what actually woke you up.

[Morbius]

What you should I do with the CPAP?

NFI.

Get your sleep fixed and then we'll talk.

I think this answers that question.
