Advantages or disadvantages of ASV machines
#1
I recently posted a copy of my SH data showing a 35.4 AHI. I visited my doctor's office last Friday. They are going to do some additional testing. They did raise the pressure slightly and see if that helps this week. So far, the AHI's have dropped somewhat. They also talked about the possible switch to an ASV machine. Have any members switched from CPAP to ASV? If so, what were the results? Advantages or disadvantages?

I would appreciate hearing from others. Thanks!

Roger, this is a fairly common occurrence for individuals that have central and complex apnea. It is normal to start patients on CPAP and evaluate whether they can be effectively treated. If they continue to have significant mixed or central events, then the ASV can be approved by insurance, however a CPAP trial is almost always required first due to the cost. Most of the member here that use ASV have very good results. I'm going to put a bug in your ear that much better success and comfort appears to occur for those put on a Resmed Aircurve 10 ASV as opposed to the Philips Respironics BiPAP Auto SV Advanced. The Resmed machine uses the patient's respiratory rate and volume as a target rather than the clock, so it tends to feel more natural to most people. Both machines have their fans. The prior version of the Aircurve 10 was the S9 VPAP Adapt.

I think you will be surprised how many members here use these machines and have had good success. Good luck!

Thanks for the feedback. I appreciate the recommendation for a ResMed machine; I think the doctor will recommend that if he finds it necessary to change. Glad to hear that there are many positive reports from those using ASV!

Thanks for your reply and I'm glad to hear that you are doing well with your ASV.

Roger - I started on an old M series Respironics cpap when C-flex was cutting edge, then moved through a number of models and modes.  As I aged, pressure requirements grew & so did the centrals, tried BiPap and then ASV.  The transition to ASV was actually the easiest for me.  It really felt the most natural breathing and I never felt I was fighting the machine on an ASV.  LOTS of fans here for the ResMed Aircurve ASV 10 - have not tried the 10.  I use and love my PR System One auto ASV Advanced (a 950 - there being a 960 introduced around 2013?) and PR just released the DreamStation ASV version last month.  Both are great machines - they do respond a little differently.

Basically the ASVs are checking what is going on breath by breath and adjusting the exhale and inhale pressures continually and they also will respond to your rate of breath - so if you don't inhale, it will switch from the exhale pressure to the inhale pressure based upon what it thinks your average breath rate is over a period of time (auto) or can also be set for a breath rate. (Sleeprider, I'm doing the Cliff Notes version here Smile )  Lots of other stuff - but the bottom line is that they are not to be feared, and in my mind, if you need more than auto CPaP, forget everything in between and get the ASV.  It can always be dumbed down, and will grow if your requirements change.
Good Luck!

Thanks, robertbuckley

I am pleased that the consensus seems pretty much unanimous regarding ASV. I'll try to update the info if an ASV is prescribed. Smile

One more ASV fan here. My AHI went from over 60 untreated to around 40 on APAP down to less than 1.0 on ASV.

I did try the then-current Philips but could not get comfortable with it. The Resmed was a revelation and I have had excellent results ever since.

Hello DeepBreathing,

Thanks! I'm really impressed with the positive results with ASV. Hopefully I will join the ASV group. Thanks
