pressure plateau

Here's how I understand EPAP PS and IPAP when using an ASV:

EPAP either as static or Min/Max range on Auto Mode will be your air splint keeping the throat open. This addresses OA based events. The E in EPAP signifies expiration pressure. In Auto Mode, it gets to be variable pressure to adjust based on need.

PS is added to EPAP to get an IPAP or inspiration pressure. Max IPAP pressures via the variable PS can kick start a breath if an event otherwise would leave you holding a breath.

As I recall, the ASV works by changing pressures breath by breath, and it does so in a way that reduces and/or avoids many instances that other machines make CA worse.

If you're within a medical necessity group for ASV, I feel your oxygen level may be less stable than others. That's not specific to you, but generically. Anyone that has an apnea event has a dip in oxygen, because breathing has been interrupted. Those with CA events, there's more potential for some apnea event to diminish oxygen.

Attempt at a simple explanation: the ASV constantly adapts the pressure to intervene before an event happens.

In that case why be concerned about blood/oxygen concentration..... if CA's will be prevented?

I've not followed this thread, but in general, an ASV will minimize, or entirely prevent, any events that can impact spo2, including centrals.

GOT SPLINTING THROAT OPEN....GOT THAT.

[PS?] (TO EPAP) PRESSURE KICK START FOR IPAP... GOT IT.

WELL, IT WAS SUGGESTED TO TEST WITH AN ASV AUTO... AND IF IT DOESN'T DO HELP THEN WHAT?

The O2 is important when doing a titration test as that shows effective treatment if the o2 remains over 90%. Any drop in o2 even on ASV will warrant further investigation

I was afraid you were gonna say that..... after the BS my Insurance company put me through already.... that's nice to know !

Don’t worry, be happy.
With ASV it’s all cool. Adaptive pressure support means events never happened so why worry about SpO2?

I have to remember not to post while listening to Reggae poolside. Oh well it works.

sounds like your confidant it will take are of centrals. I like that confidence... I tend to trust people more. 

I forgot to ask for my sleep study results..... maybe monday. I aske the sleep study center for them too. Fred asked for it...hopefully I can get it still. Still like to see it?

I had lots of CA before the ASV. The CA were afraid to show up because of the ASV.

I told my Dr. I wanted a Res Med ASV... he shook his head yes as he jotted it down... He didn't hesitate....hmmmmmmm.

One thing he said, which I never realized, but I know now, especially after learning about the ASV... and Dr. telling me this.. is when you have a central your brain wakes you up. And I've been wondering why I couldn't sleep right... and been trying so hard to.

UPPP operation..... and the uvula.

Uvula

Function. During swallowing, the soft palate and the uvula move together to close off the nasopharynx, and prevent food from entering the nasal cavity. It has also been proposed that the abundant amount of thin saliva produced by the uvula serves to keep the throat well lubricated. It has a function in speech as well.

Is this operation worth it?

The Pros and Cons of Sleep Apnea Surgery
When used frequently and correctly, CPAP is virtually 100% effective at eliminating the symptoms of sleep apnea. By contrast, a UPPP, the most common sleep apnea surgery, has about a 50% success rate.

I'm just thinking of when your old and using a PAP machine might be cumbersome. Thoughts?
