> Do I need higher pressure.
Yes

Increased EPAP to 7 and max pressure to 12. Yesterday was great (and my longest night yet), today, not soo much. I think I couldn't keep the air out of my mouth, which woke up me a few times and after about 6 hours I was not able to get back to sleep.
I am confused why I have MORE events marked as OA now at the higher pressure.

Slept very poorly last night, even though I had not a single Apnea.

Do you have an explanation for attached flow rate curve patterns? I had a lot of them in the last two hours, in which I was constantly waking up. No flagged FL, leaks or snoring.

Do you guys feel EPR should be maxed with UARS?

Of course, I leave myself open to be corrected by the experts/people with more expertise and experience, but the first flow rate to me (between 5:18:30 and 5:18:40), it looks like you were trying to take a breath but the machine wasn't catching it?

I wouldn't want to guess at that without also seeing the mask pressure trace.

and the 2nd and third flow rate graphs look like...you are maybe having mouth exhalations??

Where are you getting that?

The middle one is a big inhalation, hold then exhale...

The bottom one is normal breathing except for the burble.

Here it is: Thank you, really appreciate any input.


Had changed EPAP to 8/PS 2 last night, slept very well. Had much less of these kinds of "events", which, of course, might just be a coincidence.

At least some people think so: http://www.apneaboard.com/wiki/index.ph ... _and_BiPAP
It was the whole reason why I bought the much more expensive VAuto (even though insurance will have to pay, at least if I do have some kind of SBD).

You *might* benefit from raising the trigger setting. That could have been an attempt at a breath right about where the FOT vibrations started up.

Ok, I will try that. Do you think that could help because the pressure might be too low at the beginning of the inhale?

When you start to inhale, it 'triggers' the machine to switch to IPAP, (then when you start to exhale, it "cycles" back to EPAP. by increasing the trigger sensitivity to high, or very high, it make the machine more sensitive to the start of a breath.

If your airway is starting to close, and you're not able to get much of a breath, then it's *possible* that if the machine catches that small attempt at breathing, and switches to IPAP pressure, it may help you get that breath, instead of having an apnea.

If you're just asking 'is my pressure too low", then the answer is "yes, at that moment, it was", but probably not over all.

I try to stay disciplined and leave it at EPAP 8 with PS 2, trigger high for at least four days. Thank you for the explanation.

I have a lot less of these events now. I am generally feeling much better, however, not great yet. I would like to stay at EPAP 8 with PS 2 for another week and then maybe increase Epap a bit.

Two last nights:

Think these two episodes are interesting.

the first one you posted kind of looks like the 2nd inspiratory flow shape in this paper - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4688581/
