ResMed AirSense 10 vs. S9 autoset: Update please

How important are CS and RERA detections ?

Not really that important usually, and the way they're measured by CPAP is rather suspect. It's sort of an indication of something you might want to consider when evaluating problems. They tend to "cry wolf" and show "CSA/Periodic Breathing" at a time when there's not really much of a problem.

There are some serious medical conditions that can cause CSA. CPAP users can show a pattern similar to CSA even in patients who have nothing major wrong, and it's not harmful. If it gets really bad, this waxing and waning CSA pattern may be significant enough to cause true central apnea problems. You need to look at the waveforms to know the difference.

RERA indication is somewhat problematical as well. It sometimes shows up in CPAP data when there's not really much going on, or it may be a clue to problems.

Tried out the AirSense 10 after reading posts in this forum and other places. It took about 15 minutes to decide between a new "10" and a new "9". I chose the S9, a model I've enjoyed for over five years.

1. While the AS10 had newer styling, larger screen, colored LCD, lit knob, and a screen positioned for easy viewing, this unit sits in the bedroom, not the living room. Rarely need to look at the screen.

2. I don't use water in the humidifier chamber, but can see why people have problems with the AS10 gaskets. First, they are on the AS10 machine, not the chamber (as they are in the S9), and the S9 has one, the AS10 has two. Called two DMEs and they do not keep these gaskets in stock. ResMed should have placed the gaskets on the chamber where they are replaced when the chamber is replaced, and where they are more accessible should one elect to change them.

3. The S9 chamber can be filled without removing the chamber, but the AS10 requires the user to pull the chamber away from the machine, then flip up the top.

4. The inhalation and expiration sensation was the same with each machine set at EPR = 3.

5. Noise: It's been reported that the AS10 is slightly quieter than the S9. Yes, when running and not in use the S9 = AS10. BUT when the machines are in use via breathing, there is a substantial difference. On inspiration the exhaust area from the AS10 was not only louder, but a higher frequency than the S9. This annoying inspiratory loud blast from the AS10 was of great concern and was a deal-breaker.

This AS10 unit was factory sealed and never used until this try-out. Perhaps another AS10 wouldn't do this, so will try it again in a week with a different AS10 and make an audio recording.


There are a few more comparisons/contrasts, but these are sufficient to make a decision.

I order mine today and I am leaning towards the "for her" model specifically because it measures RERAs. That was my problem during my test. Thanks.

The Airsense For Her measures RERAs. If that is your issue, that is the machine to get. That is why I bought that machine. Sadly, I am awaiting a replacement that should show up this week. You should know that the Respironics auto ALSO logs RERAs. It's my loaner machine and it does show the RERAs in Sleepyhead. Just wanted you to know that if you were otherwise leaning towards the Respironics.

I have been told that RERA aren't scored accurately by the machines. There must be a reason why scoring is still done manually in the sleep labs

Does the S9"s Slimline hose work on the AS10?

Nope. The fittings are different.

Are you sure about that?
According to cpap.com and the product page for the SlimLine hose...it will fit both models.
Were you thinking of the heated hoses? Now those are model specific and not interchangeable between the AirSense/AirCurve and S9 models

Oooops. I first read your post as ClimateLine, the only hose I use. Sorry.
