Difference between S-Mode and VAUTO mode - Aircurve

Difference between S-Mode and VAUTO mode - Aircurve
I know this has been covered somewhere, but looking for a quick answer.

What is the difference between S-Mode and VAUTO mode on the ResMed Aircurve. I know how they function, but take this for example:

S-Mode: 15.0/11.0 
VAUTO Mode: 15.0/11.0 PS4.0

Are they exactly the same thing, or is there something with S-Mode that is different? I know these settings would show flow limits in VAUTO mode, but wondering if there is something I am missing. Thx.

RE: Difference between S-Mode and VAUTO mode - Aircurve
S-mode is fixed pressure with set EPAP and IPAP pressure.
Vauto is auto adjusting pressure with EPAP min, Max IPAP pressure and PS
When EPAP plus PS equals IPAP in Vauto mode, the result is identical to S-mode. In your example above, you could set EPAP min 11.0, IPAP max 18.0 and PS 4.0, and the device would provide auto-pressure between 15/11 and 18/14.

Ok great. I wanted to double check if it provides the exact same therapy. I know 'EasyBreathe' is an option in S-Mode and wasn't sure if that did something different.

Easybreathe is the pressure transition you feel between IPAP and EPAP on Airsense 10, 11 and the Vauto, S and ASV. Easybreathe can be turned off on the Aircurve VPAP S, and is not available on the ST. Without Easybreathe, the pressure is delivered as a square wave and can be modified by "rise-time", while Easybreathe shapes the pressure to look like a cresting wave. You can see it in the Mask Pressure graph. I don't know of any reason not to use Easybreathe as it is more comfortable and quieter.
