Sleep Therapy Devices - SOMNOvent auto-S

The Intelligent Combination of Automatic BiLevel S Therapy and autoCPAP

SOMNOvent auto-S is the first sleep therapy device on the market that combines the complete BiLevel S therapy spectrum with the advantages of autoCPAP. Titration and setting processes are minimized by the autoTriLevel principle.

Additionally a limited backup frequency ensures an adequate ventilation support according to the patient’s need in order to prevent apneas. WMtrak,  a comfortable and natural breathing sensation under safe and efficient operating conditions. All these features combine to achieve a fast therapy success and to improve patient compliance

  • Additional analog signals for PSG feed: flow, pressure, leakage, relative respiratory minute volume, respiratory status


  • Backup frequency can be set (6 - 10 1/min) for reliable response in event of apnea
  • Secure differentiation between obstructive and central events
  • Mask test and leakage visualization for check of mask air-tightness
