Flow limitation

RE: Flow limitation
I'm pretty sure I'm repeating myself. Flow limitation is treated with bilevel positive pressure therapy. Have I somehow failed to link this article? http://www.apneaboard.com/wiki/index.php..._and_BiPAP

RE: Flow limitation
Sleeprider,

Sorry to have miss-red your comments.

I was wrongly under the impression you had backtrack on those comments.

I will check if I can get a Aircurve Vauto.

Until then I will keep the current settings.

RE: Flow limitation
My first question is what can be the long term health effect of having a flow limitation higher than 0.1?
My question is based on the probability I would not be able to get a bi-level machine.

SCREENSHOT 1
Sessions 1 &2, pressure was set to 6/15.
When I woke up after session 2, I realized my mouth was open.
Not certain if the collar has shifted or not.
I then reset the pressure to 10/20 for session 3 and things got back to what I usually see.

My second question is can breathing through the mouth have an impact on the flow limitation.

SCREENSHOT 2
For the following night I kept the pressure settings to 10/20

I will try once more to set the pressure to 6/15 and see what happens.

RE: Flow limitation
We don't have any health data on flow limitation, but since it is a form of obstruction, and is the root of respiratory effort related arousals, hypopnea and OA, it is logical to try to minimize its occurrence. A mouth-open condition reduces pressure in the airway and interferes with the feedback the machine requires to measure the flow rate. We often see higher flow limit during periods of high leaks. You should probably include a leak chart to see if these events correspond to loss of pressure by leaks. In the graphs above, you are attempting to draw a correlation between pressure settings and efficacy, but have other issues that may be obscuring those results.

I think many of us using the Vauto have dealt with denials from insurance or medical systems, and choose to purchase the higher level of therapy out of pocket. My current machine is now over 20K hours and was provided through insurnace, but with the transition to Medicare it seems unlikely that will continue. I have a backup Vauto I purchased several years ago out-of-pocket and it looks like that will be my future approach to getting a machine.

RE: Flow limitation
To Sleeprider.

Thanks again for your patience with me.

I have always had weird health issues and test results.

For example, a normal person would take one or two regular Tylenols for a headache.
I took up to 5 (650mg each) with no significant pain reduction.
I did the same with different brands with the same results.
It seems painkillers don't work for me.

So I am most of the time in doubt about health issues and remedy.
This trying to explain why I would come back and ask more questions on the same subject.
Sorry for that.

SCREENSHOT 3
I have included the leak graph.
Leaks were a concern of my doctor in the past and I tried with the collar and mask tightening to reduce those. 
I was quite successful.
In this screenshot, I had the MAD, the rigid collar and added a chin strap over all.

When I woke up, the chin strap had gotten off. Maybe it explains the leak rate at the end, I don't know.

VAUTO
I have sent a request to my doctor to get the Vauto.  Waiting for her reply.

I have browsed internet to try and find a seller for the Vauto that do not require a prescription with no success.
I still have to search for a used one but I am not to comfortable with that solution since I would not get the warranty nor the support from my local provider.

Thanks again for your input.
