Cpap as backup to asv

I have ASV coming soon. I currently have a S9 autoset. Trying to figure if keeping the S9 as a backup in case my ASV ever fails. Would the thinking be the Autoset is better than nothing or is there some inherent danger with using a cpap when you normally use ASV.

Welcome to the forum.

It all depends on why you are getting the ASV.
If your sleep apnea is just central sleep apnea with no obstructives then the AutoSet won't help at all.
If your sleep apnea is a combination of obstructive and central then the Autoset could maybe help at least the Obstructive stuff.
If you have centrals and the cpap/apap pressure is what is causing the centrals then it could make things worse......meaning did you have any centrals prior to starting cpap therapy and if you didn't then the pressure is causing the centrals.

So what is your primary diagnosis and why are you going to ASV?

Thanks for spelling it out for me. I have mixed apnea and cpap is currently helping with the osa. Without cpap my ahi is 70+, with cpap it is usually in 28-30 but i have had spikes to over 120. I would say the cpsp is helpful in a backup situation but really should have an ASV. I guess my question would be is there any danger using a cpap as a backup (for the osa) if I am ever without the ASV since I would be conditioned for ASV? I'm not sure I would be able to obtain a loaner ASV should mine break or something. My DME doesn't stock new ones. I will have to ask if they have any luaners they keep around but I doubt they do.

This is a very interesting question. I also use an ASV machine for the last two years and have never had or needed a backup machine, although I have wondered about weather it would be a good idea.
Since I am switching insurance for 2016 I may look into getting the latest greatest toward the end of the year and keeping mine as a backup.

I don't know of any specific dangers with using regular cpap/apap when ASV isn't available. Obviously it isn't ideal but I guess at least treating the obstructive apneas would be better than not treating anything.

Keep a watchful eye out and you might find an older ASV type of machine that you could keep handy for a backup. Sometimes so good deals fall into our laps.
There was such a deal just a couple of weeks ago here on the forum. Used and slightly older model but the price was $150. In terms of therapy being slightly older model doesn't hurt a thing.

Fortunately failure rate on these machines is very low so it doesn't happen often but of course that's not much consolation if you happen to be one of the "very low"

If your pocketbook permits you can always get a gently used machine from secondwindcpap.com and keep it handy as a backup.

If you're interested in a used ASV as a backup let me know, I may be able to find you one.

I will keep an eye out for a used one and maybe I'll get lucky and find one like was posted a couple weeks ago. It sounds like the guy that got it really needed it andis using it, better than sitting in my closet waiting.

ASVs are out there but not all that frequently. on craigslist a fellow near jacksonville has a 950 respironics autosv advanced with 5,000 or so hours for $200, another in plant city has a 960P for $999 - not sure about the specs on it. the resmed 36037 are around sometimes, but it sometimes takes a nationwide search to find anything. overpriced resmed 36007s are more common. this is probably the best site to pick up something, a few members seem to have a supply of good goodies.

Klv329, i see you have both the resmed and respironics autoasv. What can you tell me about the differences, and why you use the resmed with the respironics as backup?

I have a 960P used ...low hours :

The proper setting for the "system one resistance" makes the two very similar to me - for me a level of 1 works well. It's like the 'mask' setting on the s9. The low hour 960P came up for grabs relatively cheap at $400 so I squeezed the budget and picked it up.

Experimenting seems to be what it takes in this almost incomprehensible apnea endeavor, and I wanted to see if there were any differences. With the relative scarcity of cheap s9 36037s, I thought I'd try it out after reading reviews that the 960P was fairly similar to the resmed s9 asv. And I get pretty nervous without a back up.

As to using an autoset s9 as a back up for awhile, well, if I had to yes, indeed. It would be a struggle but it would be much better than nothing at all. I haven't made it through a day without a cpap in 13 years because the lack of sleep is awful.

This question made me curious, so I set my S9 ASV to CPAP one morning for a second sleep session. Felt bad all day like I had no sleep, and I noticed shallow breathing followed by oxygen drops (but not below 90). Makes me wonder what causes sleep to be disturbed. May try it again for a night session just because I like pain, I guess, and to rule out other factors. Don't have an autoset anymore.

On a more positive note, my doctor didn't seem to mind that I put myself on ASV although there was some curiosity there, and mentioned that the blood tests with lower and normal cholesterol and lower and normal blood sugar may be the result of proper sleeping and oxygen. Yeah, or someone switched the test results -- my numbers haven't been that low for at least 15 years and my eating and drinking habits haven't really changed and my weight hasn't changed much either.
