ASV cost

Three sleep tests have now proven that my OSA is actually central.(natch) Does anyone have any idea what the ASV machine costs? My new sleep doctor is now going to "jump through some hoops and they're pretty big" to get my HMO to pay for the thing. I'm buying it, if the HMO turns me down, but I'm going to give them

This guy is my second opinion fellow; my first visit with him was in Nov. I've been on BiPAP for 5 years now. I had a sleep study with a BiPAP in December and the results are below. I had an ASV test last week and will get the results in about ten days.
