New Guy! High AHI

RE: New Guy! High AHI
Start there. The task is to completely ignore CA events and optimize for obstructive apnea.

RE: New Guy! High AHI
Set your VAuto back to the settings prescribed by the dr and see how bad your CA is then... I guess you will then fail Bipap and Qualify for the next machine

Questions:  

1. Is the CA data from the SD card via OSCAR accurate?   

2. My understanding is that the sleep lab measurement of CA is based on the chest and belly band numbers, rather than the data from the xPAP machine.  Are these two ways of evaluating CAs generally close in their results?  

3. Why isn't the sleep lab seeing nearly as many CAs as I see via OSCAR?  And I see them 100% of the nights I run OSCAR on them. 


I still feel pretty crappy--tired and sleepy.  Maybe I need to "go commando" and buy an ASV machine on the open market.

Thanks in advance!

Dave

Are you saying that an equipment supplier/DME is qualified, or presumes to prescribe what you need based on their unqualified interpretation of sleep study results and insurance requirements?  Only the doctor can prescribe, and the DME is the "pharmacist" that is supposed to  make it happen.  Call the doctor.

"Presumes" is exactly what happened. And, best I can tell, they didn't bother to tell the doctor!  Alas, the doctor is out of the office for the Thanksgiving holiday.  Her nurse unable to help.  

Results attached.  

Fred (et al), I'm not sure I see the benefit of squashing all the OSA and upping the CA--unless the doctor and/or DME is willing to accept OSCAR as a valid source of sleep data. *I* have tons of confidence in OSCAR (I was an assembly/machine language programmer back in the early 80's) but they don't.

Dave, you can download ResScan from the Private Files area on Apnea Board. That will give you a basis for validating OSCAR. http://www.apneaboard.com/forums/Forum-P...-and-Links

That latest chart is the kind of evidence I wanted you to have in hand. It prooves that a BiLevel is not suitable for your apnea. For now, again, make yourself as comfortable as you can. As SR said, that can easily be validated with Resscan

RE: New Guy! High AHI
Hi guys, me again.

As I mentioned, my doctor is out of town this week.  So...wondering how you would suggest I set my VAuto to mimic the APAP I had set at Min=4 Max=8.  That wasn't great in terms of CAs, but at least my overall AHI numbers were down around 10 instead of the 18-20 I'm getting with the VAuto machine set at 10 / 6.  

I'll gather data to make case for ASV later--right now I'm looking a triage mode for this week while my grandkids are here from out of town.  Smile

Thanks,

Dave

RE: New Guy! High AHI
I didn't reread this thread; apologies if this is redundant. have you tried setting vauto trigger to high from default med? I saw that it reduced ca in others so I tried it. just 2 noncontiguous nights so far but significantly fewer ca as a result.

RE: New Guy! High AHI
Thanks. Just FYI - Just got a call from the DME, They called the doctor's office and got back to me with settings for the VAuto Auto mode of 5 - 20, PS=4. I'm going to give that a try - because now I'm on the DME's radar as someone with who may very well need an ASV machine. So unless it's unbearable, I'm going to cooperate for now. Again, I appreciate the support I've received from the Apneaboard! I'll let y'all know how it goes.
