Night 8, it's already Love - Hate. So glad I found you guys!

I think your doctor is a key part of the compliance determination. To avoid an adverse finding, you should advise him of your decision to discontinue the ST therapy, and the reasons for that decision. Express your concerns about compliance, and expectation that he is actively investigating a switch to ASV. It would not hurt to convey this in writing, and keep a copy.

It seems like a simple search and some phone calls should suffice to find a doctor that has expertise in CSA and the use of ASV to treat your problem. https://www.google.com/search?q=central+...fox-b-1-ab

    Great news!  My doc finally wrote the scrip for an ASV!  This is "pre" insurance authorization, but my results so far are terrific and I believe will justify the machine.  See the chart below.  

I am having a lot of hypopneas.  I created a table which lists the AHI and a breakdown of UA and HA. How can I attempt to eliminate the HA's on ASV, any thoughts?

Note: In the Sleepyhead chart attached, you'll see the results from my entire 1 year long journey to get to here.  In October 2018 I was prescribed BPAP ST.  I used it until I protested that it wasn't the right machine for me, and had two sleep studies, to be prescribed CPAP.  We switched the ST to CPAP mode.  I used it in CPAP mode from February 2019 until July of 2019.  I continued to press, and my doc believed APAP might work.  I used APAP from July until Aug 8, when my ASV arrived.  The different s,colors represent the different machines of course. I've been using ASV since Aug 8.

unless yours is different than mine, the colors in the ahi chart are for different apnea types. so for example, the purple in your apap section is central / clear airway apnea. interesting that you had no ca before apap. asv use looks a lot better as you point out, but you should be able to better still with the help of the more-experienced members. meanwhile, include some important info in your screenshots by including the left side bar of the daily / details tab, minus the calendar and pie chart.

Not sure what settings you are using in ASV, but the usual solution to hypopnea is higher PS min. Post a daily Detail chart and we can go from there.

Hi Sheepless.  
Thanks for weighing in.  The BPAP ST and the CPAP could not read centrals, as I understand it.  They registered non-hypopnea and non-obstructives as UA - Unidentified Apneas.

[sheepless]

thanks. I learn something new with every visit!

Thanks Sleeprider, always appreciate your input.  Here are last night and a worse night, a few nights ago.

Take a look at the Soft Cervical Collar wiki in my signature links, and the examples of another member using ASV.  Do  you think there might be a resemblance?

Wow yes!  Could likely be.  I'd always been curious about the high pressure and flow rates, always in proximity to the hypopneas.  Maybe I'm dealing with positional apnea?  I do believe im worst in supine position.

I could not see this other user's PS.  What is it, do you know?

The PS setting for those 2 images on Sleeprider's post are 2-10 for the first/bad one then 2-9 for the second/good one.
