ABSTRACT:
A pneumatic system is provided for a ventilator is provided for controlling inspired and expired patient gas flow during respiratory therapy. The pneumatic system includes a pneumatic circuit for controlling a supply of one or more selected gases to a patient and a disposable patient breathing circuit for isolating exhaled patient gasses from the pneumatic circuit. The pneumatic circuit includes a dual venturi for assisting compression and expansion of a flexible gas reservoir of the patient breathing circuit.
