ABSTRACT:
An exhalation valve assembly for use in the mechanical ventilation of respiratory patients in which the PEEP valve and the exhalation valve are combined into a single valve mechanism, and which includes a wye in which the patient tube splits at equal angles into the ventilator tube and a tube closed off by the PEEP valve, so as to maintain the exhalation drive hose and the ventilator hose generally parallel, and avoid sharp angles in the air flow.
