Advanced features to promote adherence


The enhanced digital health technologies of the AirSense 11 are designed to make it easier and more convenient for your patients to start, acclimatise and adhere to therapy.1 Your patients will benefit from effective ResMed therapy modes2,3 and a range of digital support features. These provide tailored support and coaching to help them solve low-level issues independently, set up their equipment with confidence, and acclimatise to therapy on their own terms.

Direct feedback on your patients’ experience

Care Check-In* makes it easier for you to provide effective support to patients at key points in the therapy journey. It asks patients simple questions about their experience and shows their answers in AirView, making it easier for you to identify and help patients who need assistance with their therapy.4

In parallel, patients receive tailored tips to help them deal with basic equipment issues and personalised guidance to encourage them to stick with therapy.

Supported by Air Solutions


Air Solutions is a comprehensive set of digital health technologies and products that are designed to help patients acclimatise and adhere to therapy. It includes your patients’ AirSense 11 Elite device as well as the AirView remote monitoring platform and myAir, ResMed’s patient engagement app.

Other features

  • Personal Therapy Assistant is a myAir feature that uses interactive video instructions to guide patients through equipment setup and acclimatisation.**
  • Care Check-In prompts patients to share their experience of therapy. It relays feedback to AirView and gives patients access to educational and self-help tools.
  • Over-the-air software upgrade capabilities can be used to deliver maintenance and feature updates directly to devices, enabling patients and caregivers to benefit from the latest ResMed PAP features and technologies.
  • A user-friendly touchscreen designed to make navigating settings simple and intuitive.
  • AirView allows you to access nightly therapy data, troubleshoot issues at a distance, and change device settings remotely.***
  • SmartStart and SmartStop features enable patients to start therapy by breathing in or stop therapy by taking off their mask. These features can be toggled separately.
  • Advanced event detection5 can be used to identify central sleep apnoea, respiratory effort–related arousal and Cheyne-Stokes respiration.
  • AutoRamp™ with sleep onset detection starts therapy at a low pressure then comfortably ramps up to the prescribed pressure once the patient is asleep.6
  • Expiratory pressure relief (EPR™) offers a more comfortable experience, especially at high pressures, by maintaining the prescribed therapy pressure during inhalation and reducing it during exhalation.7
  • Forced Oscillation Technique capabilities enable the AirSense 11 to identify patients with central sleep apnoea.8,9
  • Built-in device diagnostic records a 10-second internal sound excerpt to track and monitor motor noise level for quality purposes.
  • Built-in ambient light sensor automatically adjusts the brightness of the device screen and switches it off when not in use.
  • Easy-Breathe motor is quiet and contributes to a peaceful bedroom environment for the patient and their partner.
  • Integrated heated humidifier can be paired to work automatically with the Climate Control feature or controlled manually.
