Ventilator (TurboVent 2)

The TurboVent 2 is a Blower to generate the pressure required for ventilation. In order to improve the mix of gases in the system, the Blower Unit generates a circulatory flow.

The TurboVent 2 is based on the radial principle, and is regulated according to requirement by an electronic activation circuit. In operation the maximum ventilation pressure is 80 mbar. The control variables used are the measured values from the pressure and flow sensors contained in the breathing system. The ventilation pressure and the circulatory flow during inspiration and expiration are attained by means of defined activation of the TurboVent 2 and the flow valve in the breathing system. The volume used to generate the pressure is the fresh-gas that is drawn out of the manual breathing bag.

The Blower wheel is inside a spiral housing. The gap of the Blower wheel to the housing is large; therefore it works like a pressure source. This fits to pressure controlled modes directly. In addition the gap enables a low insp. resistance. Volume controlled modes are performed by feeding back the flow sensor information (VTinsp) to the ventilator.

• Depending on the rotation speed, TurboVent 2 compresses the gas and therefore acts as a pressure source.
• During inspiration TurboVent 2 increases rapidly the rotation speed to reach the set insp. pressure.
• During expiration the speed is reduced just to maintain the circle flow and the PEEP pressure.

The TurboVent 2 is autoclavable (134°C)

Consequences from the Blower technology

• Allowing spontaneous breathing during ventilation at any time.
• Trigger sensitivity and trigger response on same level as high-end ICU respirators.
• Work of breathing as low as on ICU respirators.
• Supports all patients: From neonates to adults.
• Almost unlimited inspiratory flow (peak flow = 180 L/min) to efficiently respond to patient trigger.
• Providing all ventilation modes commonly used in intensive care.
