Abstract: A valve assembly for a blower driven ventilator has a first conduit (1), an inlet (2) for receiving fluid from the blower (209) and a first orifice (4). A second conduit (5) is provided with an outlet (6) for forwarding fluid to a patient (203). A membrane (8) includes a front side (9) and a back side (10), wherein at least part of the membrane (8) is movable between a closed position and an open position. A switching circuit (12) enables the selective opening and closing of a fluid connection between the cavity (11) and the blower (209) via the fluid inlet (2), a fluid connection between the cavity (11) and the patient (203) via the fluid outlet (6), and a fluid connection between the cavity (11) and ambient air (13). A control system (17) controls the switching circuit (12) during a ventilation operation of the blower (209).
