Does this mean sleep labs/centers all across the world will now be tossing and burning their effort belts, since they are apparently no longer needed to differentiate centrals from obstructives??????

If not, I think I'll keep my S8, thank you.

Did anyone notice that on the page for the S9, the "More..." link redirects to:

http://www.s9morecomfort.com

which then redirects to ResMed's main site?

I'll bet http://www.s9morecomfort.com is going to be the new site for it when it's available worldwide!

I'm in a position where I was just about to spring for the Resmed autoset II to replace my elite II. I'm having alot of trouble sleeping on my back, In fact I cannot sleep on my back at all because I need a higher pressure to do so. However my current pressure of 11 is perfect for side sleeping yeilding a very low AHI. So i thought the auto would be the way to go for me for the best of both worlds.

Would you guys and gals wait for the s9 to come out before blowing money since its supposedly more advanced and all that jazz? Or should i not hold my breath and get the autoset II now?

thanks!

From the Specifications page:
SOFTWARE COMPATIBILITY
ResScan 3.10

I'm assuming 3.10 is not 3.1 (a back version from the 3.7 many of us have), but 3.10 is an upgraded version of 3.7.

Poor numbering scheme. Shoulda called it 4.0.

Hmmm. Not enough info out to know. There is no guarantee when it will be widely available and whether the software will be available or how much it will cost or how well it will work or anything else.

Well it won't be less expensive than the S8 and the software won't cost less than the current version.

Do you know your pressure needs when backsleeping? If it is much higher than 11, the machine may not respond fast enough and you could still have many apneas.

*snicker*

I'm still with you, Jeff, on how to realllllllly differentiate between centrals and obstructives.

On another note:

jnk quoting from the ResMed site wrote: • Treats obstructive apnoeas over 10cmH20.
• Does not increase pressure for central apnoeas
• Responds to flow limitation & snoring above 10cmH20.
• Only increases pressure during inspiration not
during an apnoea

The parts you emphasized in red, despite the possibly slightly misleading (imho) way they worded the first red sentence, sound to me like they are still using the A10 algorithm. Which is fine with me. Statistically A10 has served well for a long, long time, so there's probablyno reason to think that should be changed. Not that that was what you were thinking. I'm just idly musing along here, since I'm not looking for a new machine either.

It's the second red sentence that makes me think they are still using A10. The "not during an apnoea" part. Inspiration isn't gonna happen until after an obstructive apnea is over, so...yeah, just like always, do please go ahead and start "treating" (with more pressure) after it's over, in hopes of preventing another from following close on the first one's heels, so to speak.

This also is very much what A10 does, and what other brands respond to also:
"• Responds to flow limitation & snoring above 10cmH20."

Anyway, if I were them, I think I'd have tried to figure out a way to word the first red sentence a bit differently.
Perhaps: "Preemptively treats obstructive sleep apnoeas over 10cmH20 through preventive pressure increases."

Or something like that.

It looks to me from the chart on that page that I linked to that they have slightly modified A10 so that a closed-airway frank apnea above 10 cm will now be considered a criterion for an increase in pressure--but not as a direct challenge to the apnea for the purpose of clearing it, since it will wait until inspiration has resumed to raise the pressure. However, I may be misreading the wording and the chart next to it. The last arrow pointing up on that stair-step chart seems to show an obstructive apnea occurring at 10 cm and the pressure being raised in response to it. I assume that is what the ResMed earnings report meant by "an enhanced AutoSet algorithm." Where is -SWS?!

I see what you mean about using that (frank obstructive apnea) as a criterion for an increase in pressure - after the event was over.

I guess I didn't think of that as being much, if any, different from the way A10 had already been handling obstructive apneas when the pressure was already at 10 or higher.

The more I think about it, if they are that sure they can differentiate now between central apneas vs obstructive apneas, then yes, I definitely see what you mean about a frank obstructive apnea, in and of itself, being a criterion for an increase in pressure after the obstructive apnea was over.

The "stairstep" chart of old/new....yes, I see what you mean, Jeff, and agree with you. Thanks!!

As you say, "Where is -SWS?!" We do rely on him, don't we!! And rightly so!!!

But I think you nailed that exactly right, yourself.

My understanding was that A10 stopped considering apneas (alone) as a reason for pressure increases above 10 cm, since those can be central and since reacting to the precursors, the flow limitations that would indicate upcoming obstruction, would be enough. But apparently now that it thinks it can differentiate open-airway from closed-airway apneas with FOT, it now assumes itself smart enough to go ahead and judge the apnea as obstructive even above 10 cm and to react to it even if there were no precursors.

I am sure that wording of mine is an oversimplification in some ways. And I hope my wording above does not betray my skepticism about FOT differentiation too openly.

What is the difference between "Treats" and "Responds to"??

Marketing?

Right.

By the way, sorry about the confusion when I keep re-thinking and editing a post.

Most of the time, there's "enough time" difference to get a message that there's been another post. But twice now, we've apparently hit the button at almost the same time! I'm just a fraction later and wasn't getting the notice that another post (your next ones) had already been added.

You're way ahead of me on thinking about and understanding the Enhanced bit.

I'm in agreement with you now, Jeff. Thanks for the explanations.
