Difference between Resmed S8 vs. Resmed S9??

[sugarsowner]

Hello,

I am considering getting a newer cpap machine. I have a Resmed S8 Autoset currently. I am considering getting a Resmed S9 Autoset.

I am not sure of what improvements they made if any and if there one is better than the other?
I am having trouble sleeping currently and wake up frequently with the Resmed S8.

Has anyone tried them both and seen any improvements in their sleep with the S9 autoset?

Please advise

The S9 uses a new algorithm that scores hypopneas less aggressively, and also detects clear airway apneas. I have an S8 as a travel machine and find it comfortable, though. The S9 offers the ClimateLine heated hose, which is nice in the colder months.

RandyJ,

do you sleep better through the night with the s9? Have you noticed you sleep more soundly?

RandyJ,

do you sleep better through the night with the s9? Have you noticed you sleep more soundly?

I started cpap therapy with a non-data PR System One Remstar DS 150 and after a few months switched to the Resmed S9 Autoset and always slept through the night with both machines. I acquired an S8 Elite that I use as a travel machine, and sleep through the night with that as well.

Could there be something else, like mask leaks, that is waking you up?

I am delighted to know about algorithms but ....Has anyone had a better nights sleep with an S9 Autoset rather than the S8 Autoset? And if so, what non technical reasons
have you noticed?

Please advise

There is a major difference between in the S9 and the S8 in how they identify and respond to apneas - especially at pressure above 10 in Auto mode. That means they will give you different therapy.
The S9 also has a different - improved - way is supplying humidity

The S9 is noticeably quieter, its air supply is somehow smoother, I sleep better with mine.

Have you ever looked at your results on the S8?
Try to rent an S9 for a month - then you will be able to feel how the new technology affects your sleep.

Furthermore, the S9 is much better for troubleshooting than the S8, so even if you won't sleep better on it, you could use its improved data gathering to discover what happens to your breathing before you wake up.

You may even discover (if you try it) that a Philips machine suits your breathing pattern better than a Resmed. If you try it, that is - it's not something one can base on theory. I know a Philips Respironics is not good for me, because I tried it. I bought an S9 after trying other machines, the S9 included, not before.

I don't think any machine will be so different that it prevents you from sleeping. I would look at other causes.

My two brothers in law are using ancient machines and sleep great. I actually slept better with my old F/P non data machine than with my S9 but I am not attributing the change to the machine. Rather I am just more anxious about other things....and fatter so not comfortable.

Maybe you should talk to your doctor before investing in a new machine and finding that it doesn't solve your problem.

THe S9 has a lot of new features like:

1) Heated Tubing
2) Rainout control
3) Smartstart for full face masks
4) Lighter wieght
5) quieter
Plus it looks cooler.

Here are some educational videos about both machines http://www.cpaplibrary.com/machine-education

Mine doesn't have smartstart for full face masks. Is that the newer firmware?

I'd be very interested in additional information, if you have them? I recently upgraded from S8AutoSet to S9 Auto. I haven't noticed any major difference in sleep patterns. Maybe too early....

You'll find lots of info about the Resmed algorithms in my older posts.
Google berthon-jones +algorithm site:resmed.com
And you'll find info about the S9's different handling of central apneas in the S9 site.

I found the clinical trial validating CSAD and new ResMed AutoSet algorithm. Not sure if I fully understand it but appears the improvement only applies in situations when patient has centrals. In other words, it doesn't necessarily improve sleep for all patients, only the sub-set that experience CA...is that a correction conclusion?

. . . The S9 is noticeably quieter, its air supply is somehow smoother, . . .

Would that be true going from an S8 II to an S9? If so, that might actually influence my decision for myself in a year or two.

Yes, S9 super quiet. That's the first thing you notice when making the change.
