The S9 AutoSet™ is ResMed's premium auto-adjusting device, designed to help patients comfortably adjust to sleep apnoea therapy and encourage long-term compliance.

The S9 AutoSet responds to flow limitation to pre-emptively treat apnoea events and prevent more serious, subsequent events from occurring. Using ResMed's enhanced AutoSet technology, it automatically adjusts breath by breath, as a patients respiratory needs change - hourly, nightly and from season to season - to deliver the lowest therapeutic pressure. As a result, the AutoSet algorithm has been clinically proven to increase patient comfort and compliance.1-3
