S9 AutoSetTM with H5iTM humidifier

The S9 AutoSet™ is an auto-adjusting device, designed to help patients comfortably adjust to therapy and encourage long-term compliance.

The S9 AutoSet responds to flow limitation to pre-emptively treat apnoeic events and prevent more serious, subsequent events from occurring. Using ResMed's gold standard enhanced  AutoSet technology, it automatically adjusts breath by breath, even as needs change - hourly, nightly and from season to season - to deliver comfortable and efficient therapy pressure. As a result, the S9 AutoSet is clinically proven to increase patient comfort and compliance.1-3

Intuitive design

The user-friendly controls and intuitive interface easily guide patients through their sleep report or settings, and extra features like SmartStart/Stop and Mask Fit can be added at their convenience.

Other features

  • The central sleep apnoea (CSA) detection feature differentiates between obstructive and central apnoeas so you can be confident that your patient receives appropriate therapy and pressure.
  • Detailed data options, including a 7 day high resolution flow data, allow you to monitor therapy progress to ensure any issues are detected and addressed early, helping you deliver high quality patient care.
  • Easy-Breathe technology delivers air in a smooth waveform that intelligently follows the patient's natural breathing pattern, resulting in a truly comfortable therapy experience.
  • The Easy-Breathe motor includes more performance reducing the system noise, which creates a peaceful environment for the patient and bed partner.
