[Treatment] Flow Limitations, a problem or not?
#11
RE: Flow Limitations, a problem or not?
having major issues with foggy brain/fatigue. The last year has been a train wreck, just getting organized enough to focus (no pun intended) on my foggy brain and fatigue again. Have set my machine to what you see on profile I will post results after a couple of nights...thanks all....

RE: Flow Limitations, a problem or not?
My understanding of ASV has evolved to where I expect to see what appears to be flow limitations in users that are dependent on pressure support to initiate or sustain inspiration. While the ASV can certainly keep you breathing, the reliance on the machine's pressure support results in an inspiratory peak that appears flow limited, as compared to inspiration by a normal person with spontaneous inspiratory effort. This does not explain why you continue to feel fatigue or brain fog, only that I tend to dismiss flow limitation as having the same meaning when using any bilevel with a backup rate, and especially where high pressure support is persistently needed to maintain respiratory volume and rate.

Nice to see you back at it, and we will of course do what we can to help.

RE: Flow Limitations, a problem or not?
This was last night...After reading Sleeprider's post, which has confirmed what am afraid of, I would like to see if any tweaking will help
but understand that it probably won't...lol

I'd like to see the full picture of events and pressure range. Please be sure to minimize the monthly calendar and turn off the pie chart.

I am not expecting any improvements in this, just more getting conformation that the machine is doing its
best, and my foggy brain is another issue....
thanks for any adjustment suggestions...

Do you have an Oximeter ?

It would be good to check your not getting any desaturation but the numbers from the ASV looks good

RE: Flow Limitations, a problem or not?
I used to have one, was reading a thread about them last night, been thinking it would be good to
check O2 levels again...
Thanks for the suggestion...

RE: Flow Limitations, a problem or not?
AHI is incredibly low, but as you can see the machine is backing up breaths more often than not. Your median pressure support is over 5-cm, so my suggestion is that we try increasing the minimum pressure support to stabilize pressure. Currently your minimum is 2.0, but I could see your minimum PS being much higher. Let's try 3.0 to start, and I expect we will move to 4.0 or 5.0. The objective in these adjustments is to implement the PS into the settings instead of relying on the machine to make them. This should make the therapy more steady and restful.
