I know that is what they say but I have only seen one person's reports who actually gave me reports from both Autoset modes at the same settings and I am not so sure that it deals with them "better". The for her algorithm is more sensitive and will report more FLs than the other auto mode at the same settings. Response isn't quite the same either and more pressure didn't really help the FLs shown on the graphs.
It was only one person though. I think their idea of "better" is based on the assumption that women tend to have flow limitations and are highly sensitive to pressure changes so they went the kinder gentler route in dealing with them...but I am not so sure that's a good valid assumption to make for women in general..much less the general population.
They have to use more pressure...it's just delivered maybe a little softer which may or may not end up being "better".

If it were me with the above choices...no question.. the AirCurve 10 VAuto.
And that's coming from someone currently using the AirCurve 10 ST in S mode....I don't have auto mode available...sure wish I did. I am okay with it...I knew what I was getting but if I had a choice and money was the same no matter what...the VAuto AirCurve. You can do so much more with it...even use it like an apap if you want.

sure, whatever.

it was your video showing the flow limitation/narrowing of the airway stages leading to apnea, a total blockage. timeframe 1:12 to 1:30 ..Now YOUR video isn't good enough? sure, whatever, an apnea isn't a flow limitation either

no, the point is that getting through to you is a lost cause.

a "flow limitation" in the context of data recording cpaps, is a specific type of restriction, verses your slathering on the term as "anything that limits your airflow, like an apnea".

surprisingly, the machines *don't record flow limitations* at the same time they record snores, or hypopneas or even apneas. *because they are all different modalities*.

now, you *could* have an apnea after a FL, but *IT IS NOT A CERTAINTY*.

you *could* have a snore flagged near a FL, or you could have snores *WITH NO FLs FLAGGED*.

but, all these fine points are slathered over with the broad brush you're painting with.

and I'm done, I think most cognitive able people reading this thread have been able to figure things out, and that's all I really care about at this point.

I stand by your video, they are all flow limiting events. If you didn't agree with it, why did you post it?
You would have to look at the algorithms to see what criteria they class the different limited flow rate events. Different manufacturers have different criteria. when does a hypopnea become an obstructive apnea? How may hypopnea events are need within a timeframe to be flagged as a hypopnea?
but you are welcome to have the last word, I'm done.

that might or might not be true for YOUR specific machine - but in general that statement is completely wrong!
As - already pointed out - FLs are not bound to inhale - as is snoring!

But besides that I stand by what I said: although snoring is by definition a flowlimitation, calling snoring a flowlimitation is in the same category as saying an apnea ist just a bad hypopnea.

My take on your argument over semantics and definition is that Flow Limitations are a specific type of flow reduction as are apneas, snores, and hypopneas.

That would be my take also. Interesting paper...puts into scientific words that my common sense logic has always thought.
There's a reason that these auto adjusting machines will increase the pressure in an effort to kill FLs. They are unwanted and potentially disturbing factor to sleep quality by potentially causing arousals....and we all know arousals mess with sleep quality.
And further demonstrates what we have all know...it ain't all about the AHI alone.

Great article, thanks Jay. Really points out the importance of making sure that we all are talking about the same thing begore talking.

snoring isn't "bound to inhale" either.

yes, thank you.

that's what I tried to say - might got lost in translation.

as you could see in the picture there is absolutely no problem to have both - snoring and flowlimitations - at the same time.

indeed, you can .. but the point that some people are unable to grasp is that *they are separate things* sure they can happen at or near the same time.
