E-Vent

The E-Vent doesn´t need any kind of driving gas due to it´s electric driven functionality. This reduces costs and allows a longer operation without a central gas supply. In case of an emergency the ventilation can also be performed with ambient air.

E-Vent Performance

  • The electrically driven E-Vent ventilator delivers highest precision and speed as well as a peak flow of 75 L/min in Volume and Pressure control and 85 L/min in Pressure support.
  • Fastest reaction times needed for assisted spontaneous ventilation modes.
  • Achieves almost the same performance as an intensive care respirator.
  • Expiratory flow controlled ventilator piston return. The ventilator synchronizes itself with and actively supports expiration, which considerably reduces the expiratory resistance.
  • Very rapid dynamic compliance compensation and Minimal inspiratory system compliance.
  • Unrestricted applications, including especially pediatric ventilation
  • Fresh-gas decoupling.

    • Ventilator Technology

  • Electrically powered and controlled piston cylinder unit with 2 rolling seals
  • Piston pump generates negative pressure between the two membranes (high leak tightness)
  • Drive takes place through recirculating ball screw of a direct current motor which is fixed to the piston
  • The vertical movement of the spindle transfers the corresponding volume towards the patient (tidal volume: 1400 ml)
  • The signal of the high resolution incremental encoder determines the position of the piston cylinder unit and allows precise volume dosage in 5µl range
  • Light barriers to detect the lower stop position of the piston cylinder unit ("zero position").

  • The position of the piston cylinder minimizes the volume and inspiratory system compliance
  • In Standby mode, the piston returns to the lower end position, ready for the first breath
  • In Volume mode, the piston moves back by the amount of tidal volume to be delivered (VT x 1.4)
  • In Pressure mode, the piston starts at the lower end position to allow application of any size of tidal volume
  • In MAN/SPONT mode ventilator volume is utilized.
