A ventilator assembly for use in a ventilator circuit for administering medication to a patient comprises a housing defining an inhalation interior space and an exhalation interior space separate from the inhalation interior space, and a ventilator port positioned at a first location of the housing, the ventilator port defining a first passageway in communication with the inhalation interior space and the exhalation interior space. A patient port is positioned at a second location of the housing, the patient port defining a second passageway in communication with the inhalation interior space and the exhalation interior space. A one-way inhalation valve is positioned in the housing adjacent one of the first or second locations to permit one-way flow from the ventilator port to the patient port through the inhalation interior space. A one-way exhalation valve is positioned in the housing adjacent the one of the first or second locations adjacent the position of the one-way inhalation valve to permit one-way flow from the patient port to the ventilator port through the exhalation interior space. A receptacle is positioned on the housing and in communication with the inhalation interior space, the receptacle operative to receive a container comprising an aerosolized medication.
