Abstract
A device for flushing a deadspace during mechanical ventilation of a patient with a ventilator includes a reservoir having a variable volume container, such as a balloon, adapted to receive and hold a portion of the pressurized breathing gas provided by the ventilator during an inspiration phase and to supply, at least during a final part of an expiration phase, the received breathing gas as pressurized flushing gas to a first end of a conduit which is disposed in a patient's airway. The reservoir has an outlet in pressure communication with the first end of the conduit and operable to supply the flushing gas as a result of the pressure at the first end of the conduit falling below that of the gas within the reservoir.
