New to ASVauto

[SDM1]

    Hey all,

I just completed my 2nd night with a new Resmed Aircurve 10 ASV, my numbers look really good but my sleep keeps being interrupted by what I assume high pressure. How does one limit the high-end limit of the pressures on this machine? or should I not be limiting either way on this since it's an Auto machine?

It's possible to edit settings where they won't negatively impact the ASV therapy. First we'll want some other OSCAR charts to help guide.

Events
Flow Rate
Pressure or Mask Pressure
Leaks

Certainly skip flow limits, as the ASV algorithm actually gives FL artifacts in this section. Most will have some activity on FL on ASV and you can't tune it out without hindering CA therapy.

Be sure to state some settings you've tried.

Here is the Oscar report you asked for, the only change I have made was to raise the EPAP min from 4.0 to 7.0.

OK got it, thanks.

Here's a combo I'd try.

Edit EPAP Max down 1 to 11, gives EPAP 7-11.

PS: I'd consider edits to both Min and Max. I felt better with using ASV if there's some differential always, as in some PS. Try PS 3-10. This makes your overall just 1 less on IPAP Max, but PS should fire then drop.

Try it even a few minutes, see if this changes it enough.

We can edit again if needed.

Okay, Thanks.

I'll give it a try!

So, I slept better (Longer Durations & kept mask on) but UA's & Hypopnea's took over. Thoughts???

Try setting PS Min to 2.0. Having some pressure support on every breath makes it feel less abrupt when the machine kicks in more PS to manage breath volume or rate. Your current setting are PS min 0.0, PS max 10.0. Make that PS min 2.0, PS max 10.0

Hello ALL!

So, I have been getting better sleep with this new ASV machine than I think I have in my life. My 90-day AHI is around 3.0 but I have nights like last night that it bounces up to 4.77. My doctor tells me that once I've got my settings to where my average AHI is at or below 5.0 to leave them alone, I say if I can get to 5.0, then I can do better. Looking at the charts from last night below, does anyone see something that I should adjust?

You were doing better with EPAP 7-11 in my opinion.

I would put this EPAP range to something like that again. You won't need EPAP 15, and your Hypopnea say to me they need more than EPAP 4 you have now.

I also would get PS minimum to 2, and 3 might be needed later.

I'll add the ResMed ASV Titration. You can certainly try this method. And getting the ASV set right, two things will happen, unclassified will diminish and you'll be comfortably under AHI 5.

Thanks Dave,

I've never seen this sheet before and can see that it can help. If I move my minimum PS above 1.4 it makes it to where I can't sleep, don't know why but every time I try it higher the mask hangs on the bedpost. Per directions I'm going to try raising the minimum EPAP a little at a time, when I have raised it in the past in typically blows my pressure numbers way high and then the leaks start. Instead of raising by a full point like I've done in the past, I'll raise it .2 at a time until I figure out the HPA & the UAO. Doc tells me to not worry about the max numbers since the Auto ASV should never go where it isn't needed. Do you agree?
