A spacer assembly (10) for a ventilator or other respiratory equipment for dispensing aerosol drugs from a metered dose inhaler (MDI), canister (80) or nebulized drugs from a nebulizer port (40) into a respiratory gas stream delivered from a ventilator or other respiratory equipment connected to a patient. The improvements involve optimizing the shape of the spacer assembly body member (12/14) and providing an efficient MDI nozzle assembly (36) to allow maximal evaporation of the propellant before the propellant droplets impact the walls of the body member while providing a compact volume for directing the output of the MDI canister or a nebulizer into the gas stream.
