The previous phase of getting started using cpap again and determining settings is here: viewtopic/t115992/Vote-on-the-starting-settings.html. Apparently the Flow Limitation graph is 'active', and I'm trying to figure out how much it was involved in cpap not working effectively for me previously.

please stop making a new thread for every random thought you have, keep all your stuff together and it's easier to help you.

also, stop obsessing about the past, "and I'm trying to figure out how much it was involved in cpap not working effectively for me previously. " the past is the past, focus on now, and go back to the other thread where the question was raised, and follow through.

Thx - you said it better!

I don't know how much of a part these flow limitations are playing in how you feel.
Your awake breathing shows more flow limitations than I expected but it's fairly obvious that your asleep FL graph is still more active.
Is this UARS maybe? I dunno. It wouldn't be impossible.

If I have time today I am going to try the awake experiment with my machine in cpap mode to see what my FL graph looks like.

Do you happen to remember what your original sleep study showed in terms of AHI and oxygen levels? The diagnostic sleep study...without cpap.
Do you still have your tonsils and if you do are they very big?
I still have mine but they have atrophied to the point they might as well be gone.
Were you experiencing any nasal congestion at all during the awake experiment?

I am including links to the other 2 relevant threads in case someone hasn't been following.

viewtopic.php?f=1&t=115992&p=1127363#p1127363

I thought I saw the FL snippets in another thread but I can't find them now so there may be another thread that I am missing.

one of the things to keep in mind while trying that experiment, wake breathing is typically much less regular than sleep breathing, with pauses, and irregularities, and those, as we know, play havoc with the machine that assumes you'll be asleep and breathing regularly.

so when doing your experiment, I suggest trying to focus on your breathing, and try and have a few minutes of nice, even, regular breathing, without doing anything much else.. maybe a little meditation

Well crap. My Aircuve 10 ST doesn't do flow limitation graphs even in CPAP mode.
Also it doesn't seem to have EPR available either. That surprised me about no EPR.
High dollar machine doesn't do FL graphs and does not offer EPR in cpap mode. I knew it didn't offer EPR in the bilevel modes but not having it in CPAP mode surprised the heck out of me.

even? Isn't it the mode when it won't register FL?

The model AirCurve 10 that I have has 4 different modes. 2 of which I have tried...CPAP and S (which is really just a fixed bilevel mode) and neither mode offers FL reporting of any kind...no numbers or graphs.
The other 2 modes won't have it either as they are just fixed bilevel with back up rates available to force me to breathe at the rate setup and I don't want to do those modes and I don't need those mode.

I have a PR S1 machine but the way Respironics reports FLs is totally different and we don't get any graphs with it and it's the graph I was wanting to see.

The AirCurve machine I have doesn't do any auto adjusting at all of the pressure in response to events or snores or FLs. So maybe that's why the machine doesn't record any FLs....it can't do anything about them anyway.
I figured it wouldn't do an FLs in S mode but I thought it would at least do it in CPAP mode but it doesn't.
I also don't have EPR in CPAP mode. I guess since S mode with PS functions like EPR functions they just offer bilevel mode for those that want EPR.

min 11, max 20.

If your numbers look pretty good (and they do) and apart from a possible small boost in pressure you might want to try, I wonder, seeing as flow limitations are a problem, if you'd consider trying a soft cervical collar that would keep your airway more open, especially if you end up with your head down when sleeping, and a collar would keep it more upright, allowing a smoother flow of air.

Apparently the Flow Limitation graph is 'active', and I'm trying to figure out how much it was involved in cpap not working effectively for me previously. As well as trying to discover any other factors in my control that can influence the outcome towards success.

Below are flow limitation graphs comparing 2 situations. The top one is while awake (first half of it lying on my side, second half while sitting up). All subsequent rows are from various sections of the previous night's graph, displayed in approximately the same time increment and scale. I'm only starting to learn about flow limitations, so I'm not sure how significant the differences are, or whether and what of interest or useful the graphs show...

desiderata, what kind of mask are YOU using? Is it discussed in your previous post(s)
