ResMed S9 AutoSet™

Able to differentiate between obstructive and central sleep apneas.
Manufacturer: Resmed

The S9 AutoSet™ combines an intelligent algorithm with Easy-Breathe expiratory pressure relief (EPR™) to dynamically adjust pressure for maximum comfort. Using ResMed's time-tested APAP technology, AutoSet™ continually monitors breathing, adapting breath-by-breath to always deliver the lowest therapeutic pressure, improving comfort and sleep. Enhanced AutoSet is now able to differentiate between obstructive and central sleep apneas, so you can be confident that you are always receiving appropriate therapy and pressure.
