Abstract

The invention relates to a ventilator system comprising an inspiratory gas supply subsystem for supplying gas at a pressure above ambient atmospheric pressure, a ventilator module connectable therewith through a gas supply pipe system allowing gas communication, and comprising a gas discharge pipe system for discharging gas from the ventilator module, characterised by comprising a plurality of ventilator modules each having an inlet side and an outlet side, the gas supply pipe system comprising an inspiratory bus having a gas inlet segment and comprising a plurality of inspiratory pipes which are connected directly or indirectly to the inspiratory bus downstream of the gas inlet segment, each inspiratory pipe is connected to or connectable to the inlet side of one of the plurality of ventilator modules, and the inspiratory gas supply subsystem is connected to the gas inlet segment of the inspiratory bus for delivering inspiratory gas at a first pressure higher than the ambient atmospheric pressure into the gas inlet segment, the gas discharge pipe system comprising an expiratory bus having a gas outlet segment and comprising a plurality of expiratory pipes which are connected directly or indirectly to the expiratory bus upstream of the gas outlet segment, and each expiratory pipe is connectable to the outlet side of one of the plurality of ventilator modules, the ventilator system further comprising an expiratory gas discharge subsystem being in gas communication with the gas outlet segment of the expiratory bus for producing a second pressure lower than the ambient atmospheric pressure in the gas outlet segment.
