An adaptive-servo ventilator designed specifically to treat all forms of central sleep apnea (CSA), including complex and mixed sleep apnea.


Unlike conventional sleep disordered breathing (SDB) therapies such as continuous positive airway pressure (CPAP), adaptive-servo ventilation:

  • Treats complex sleep apnea syndrome (CompSA) and CSA
  • Normalizes breathing, completely suppressing CSA and/or Cheyne-Stokes respiration (CSR)1,2
  • Improves sleep architecture2 (increases amount of time the patient spends in slow-wave and REM sleep)
  • Enhances quality of life for patients with CSA2,3


Support when it's needed

Our adaptive-servo ventilation algorithm:

  • Adapts to the patient’s ventilatory needs on a breath-by-breath basis
  • Automatically calculates a target ventilation (90% of the patient's recent average ventilation)
  • Adjusts the pressure support to achieve it


Maximizing patient comfort and compliance

  • Ensures pressure support is synchronized to the patient's own recent breathing rate and flow pattern
  • Provides a constant, low level of pressure support
