ASV users: the everything ASV thread.

Last night, again EPAP=4, PSmin=3. Still feeling better than without CPAP, but not as good as I think I should be. I may keep along this track for a while and see what happens.

Not a bad approach. Some of your PTB is 100% at times, which is better. PB is not, however. What is your PSmax right now?

-A

PSmax is 30. Someone mentioned in another thread that keeping it at 30 can burn out the machine more quickly, though I don't know if there is any truth to that.

As for PB, I looked at a report the DME sent me (my first report, just before I got the software and reader) and I had a night where my first two hours of PB were straight bars. The PB was so bad that all the individual bars connected into one long bar. That just seemed like a particulary bad night.

Are you sure PSmax is 30 and not Max pressure (two different settings)? PSmax should be Max pressure (30) - EPAPmin (4) = 26. You're not even close to your PSmax (or Max pressure), which is kinda strange since the timed pulses (for me) are commonly well into the 20's. I just want to make sure it wasn't set to something low and limiting the pressure on the timed breaths. We all have bad nights with some PB. I had some last night, myself. Hopefully, they go away for us both tomorrow night.

Yup, you're right, I'm not familiar with all the terminology, abbreviations and acronyms yet.

Max PS= 18cm

EPAP Max = 18cm

I would check the installed settings on your machine just to be sure. I've noticed in the past that if I change one value, other values I don't want to change might change as well and I have to go back and set them back to the vales I want. It's also possible that your DME did not set up the machine properly, too.

Those pressures are from the machine, I originally checked the prescription, but then I went and checked the machine itself just to make sure.

Okay, thanks. I feel better now.

PSmax is 30. Someone mentioned in another thread that keeping it at 30 can burn out the machine more quickly, though I don't know if there is any truth to that.

No, there is no truth to that. Just because you set the max at that, it doesn't mean the machine will be running at max all of the time. You could set it for 20 billion and if the machine never got that high, it would have no effect on how quickly it wore out. (Well, really, you can't set it that high, but you get the idea!)

Thanks Deborah and Ozij, that's what I figured. I'll have to find that thread and post because I don't think anyone challenged it.

Actually, I find it interesting that the new PRS1 ASV Max pressure is 25, where Max pressure on the older "tank" is 30. I wonder why this might be... Do any ASV users out there ever see their pressures go above 25?

timbalionguy debunked it:

If your machine works like the BiPAP SV advanced machine, the motor only speeds up when higher pressure is called for. Unlike what Banned suggests, the motor does not run to supply 30 cm at all times. My machine is set to 30 cm max pressure. While I have heard it really wind up every now and then, most of the time it runs at a low RPM. It will speed up moderately if it decides some ASV action is called for, but not a lot of action.

Interesting sidenote -- Coincidence? ....that the only two people I've seen making the ridiculous assertion that having Max IPAP set high will "burn" out the machine are:

Dave, Dave, I splain it to you, and you never listen! How many BiPAP Auto SVs are you going to burn through? If my count is correct, you are working on destroying your 4th ASV? Your Max IPAP 30 is too high. Turn Max IPAP down to 25. The machine will will not overheat, your wife will not wake up, and you will not die because you you were 5cm short on an IPAP spike. The problem with the BiPAP Auto SV set at MAX IPAP 30 is that even though you are not using IPAP 30 in the moment, the machine is working harder ALL THE TIME at Max IPAP 30, then at Max IPAP 25. Give your machine, yousrelf, and your wife a rest, turn Max IPAP down to 25cm. Anyway, good to hear from you!

AND someone who thought it would be amusing to register a name (StillAnotherGuess) confusingly similiar to that of a longtime regular member (StillAnotherGuest):

but what's gained by lowering the max pressure to 25? From the graphs, it never gets close to that high as it is.

Your device will run more efficiently and provide longer device life at lower Max Pressure. You could happily set Max Pressure 20. People on this board love to run there devices at the highest possible Max Pressure. It tears these machines up, as has been demonstrated many times with run-away pressures and burnt-out machines, by many forum users. Running your device at Max Pressure 30 is almost as dumb as the person who set your device parameters to run on 'Auto'.

Please note that "StillAnotherGuesS" is a very very new poster. S/He is not the poster known as "StillAnotherGuesT".

If the machine does not get to the higher pressure, it won't get "burned out". I would never trust a poster who registered 2 weeks ago on statements about what "has been demonstrated many times" or about "many forum users".

As a matter of fact, I would automatically distrust any posting by a poster who chooses a name so similar to a well known well respected other poster on the forum.


Caveat emptor.

I agree, I've been wading through some of the posts and posters trying to figure out who and which to trust and which to ignore.

That's not always an easy proposition, when there is so much to absorb. But you seem to be doing a yeoman's job at learning. Hopefully, it will lead to better sleep and better feeling during the day in the near future!
