A manifold nebulizer system for use in a breathing circuit. The system includes a nebulizer module and an exhaust module. The nebulizer module consists of a vial to contain liquid and has structure for producing an aerosol of liquid particles for entrainment in a stream of gas. The exhaust module has a valve for facilitating inhalation of the aerosol by the patient and removal of exhaled gases received from the patient. Adjustable surfaces are on the modules to permit relative movement therebetween. In this manner, the manifold nebulizer is capable of assembly into a multiplicity of flow line arrangements and positions.
