FWIW, there is no such thing as an S10. The last of the S-series (by name at least) was the S9. The current model you want is the AirSense 10 or AirCurve 10 if you want a BiPAP.
Anyways ... I have an AirSense 10 and I have to say ... I have no idea what the S9 was like, but the current model still fucks up my levels when I wake up in the middle of the night. Not sure how my breathing is different when I'm awake, but it inevitably causes the damn machine to detect an obstruction and it will push the pressure all the way to the maximum.
A pretty common complaint, but they have not released a fix AFAIK.
