1. A ventilator chamber for use in a ventilator circuit for administering medication to a patient, the ventilator chamber comprising:
a housing comprising:
a chamber defining an interior space having an input opening and an output opening;an input port defining an input passageway communicating with said input opening and adapted to receive a flow of gases from a ventilator intake line, said input port further comprising an inlet spaced apart from said input opening and formed at an end of said input port;a metered dose inhaler receptacle in fluid flow communication with said interior space;an output port defining an output passageway communicating with said output opening, said output port further comprising an outlet spaced apart from said output opening and formed at an end of said output port; andan exhaust conduit communicating between and directly with said output passageway of said output port and said input passageway of input port; wherein an inhalation pathway having a first length is defined from said inlet to said outlet through said input passageway, said interior space and said output passageway; and wherein an exhalation pathway having a second length is defined from said outlet to said inlet through said output passageway, said exhaust conduit and said input passageway, wherein said second length is less than said first length.
