Timely feedback with Care Check-In

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 faster for you to identify and help patients who need assistance with their therapy.1

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

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.

  • 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.
