Flow limitations

Flow limitations
Is there anything in these charts that would indicate what is causing these FL's?
Was my first night trying a P10 nasal pillow.  Also slept with a soft collar to help with jaw drop.

RE: Flow limitations
I don’t see a problem your flow limitations, nothing is jumping out fix me I would reduce the EPR to 1 and you may find your CA’s reduce if they are normally at this level. Other than that how are you feeling and sleeping

RE: Flow limitations
Your charts look good to me but I’m not an expert. If you feel good I would keep it as is. If it was me and I didn’t feel good I would put EPR on 3 and bump up the minimum pressure by 1cm h20 and give it a few nights. 

That’s not a recommendation It’s just what I would do

RE: Flow limitations
I would have to echo jaswilliams recommendation.

Set EPR to 1. (This may clean up a couple Clear Airway events.) They really aren't much, but that’s what I would do.

I don’t see a problem with Flow Limitations. Your FL readings are pretty low.

RE: Flow limitations
Thank all of you. Prior to recently starting APAP I felt exhausted/run down constantly. Been doing a lot of searching here on AB and a little fine tuning on my end, and have been feeling like I am getting a better quality of sleep, morning headaches are gone, and muscle cramps are gone (Dr felt it was hypoxia).
I found that if I set EPR to 3 that I have more CA events along with H and RE and feel generally poorer upon waking.
With EPR at 2, I get the few CA's (as shown) but no H or RE (typically). And generally feel rested upon wake.
With EPR at 1 or 0, there are virtually no events, but I feel horrible in the AM. Like I didn't sleep at all.
So for right now EPR 2 seems to be my happy medium.

The pressures seem to be working well for me. I recently lowered my Max to 14 because anything 15+ would give me a horrible headache.

RE: Flow limitations
Just a guess, but you might see whether the little bursts of FL continue to show the kind of pattern we're seeing here. Especially in light of your respiration-rate changes, this might be a REM-related phenomenon. In any event, nothing to worry about, it seems to me.

RE: Flow limitations
Late to the game, but there is nothing of concern here related to flow limitation. There are a couple periods of low flow limitation that work to increase pressure, at which point the flow limits resolve. This is exactly as designed. I agree with your conclusions that higher EPR would be counter-productive, and this looks effective and comfortable. Well done!

Dormeo, I've been trying to compare my fitbit data with that in the OSCAR charts to do exactly that.  But it is frustrating without being able to have all the sleep data right in OSCAR.  Someday I may invest in one of those EEG sleep monitors...

Sleeprider, thanks.  It's been an interesting journey.  Lots of great people here to learn from!
