I'm a little confused by some definitions. I was diagnosed as complex apnea - central and obstructive, Have been on ResMed Aircurve 10 ASV since 8/3/15. Downloaded SleepyHead and looking at results. There have seen some UA's and Hypo's. My AHI on 11/22 was .55 as compared to 30.9 during testing back in July (2nd study). Is central apnea the same as hypo-apnea? I was told by Sleep Medicine that as a result of using ASV, I have NO obstructive apnea's.
PS: still having issues with mask popping into my mouth and leak rate was 8.74 on 11/22. Experimenting with different mask loaned to me by the service - only difference is in headgear not mask itself.

Re: Difference between Central and Hypopnea
With central, there is no effort to breathe for at least ten seconds or more. A hypnosis is a partial blockage that restricts your air flow.

Re: Difference between Central and Hypopnea
So how is Central reported ? The only things I see are UA and hypopnea?

Re: Difference between Central and Hypopnea
With the ResMed ASV machines there is no separate category for central and obstructive...they both go into the AI or Apnea Index basket. Don't ask me why ResMed elected to do this...I don't know but they just do.andycole wrote:So how is Central reported ? The only things I see are UA and hypopnea?
Most hyponeas are partial obstructions...baby OAs if you want to think of them that way. Though in some situations the machine can be fooled and might label a central with a hyponea flag...not common though.
Because the ResMed ASV doesn't separate centrals and OAs with SleepyHead you get UAs and if you used ResScan software what you see as UA on SleepyHead would simply be called apnea in ResScan.
I use a ResMed ASV and I have both SleepyHead and ResScan and the Apnea Index is always what my UA index is in SleepyHead.
Hyponeas are separate in both software programs.
In general we assume that the UAs in SH and the apneas in ResScan that do get flagged are most likely obstructive in nature though. We trust the machine to be dealing with the centrals and no need for a flag for them.
If your AI or UA and total AHI is quite low...doesn't matter anyway because everything is being treated.
So with ResMed ASV...you are going to see UAs in SleepyHead and it doesn't mean that SH can't tell what kind of apnea it is...it's the machine not putting a name to whatever is being flagged causing the "unknown apnea" classification.
