A unitary breathing head device for administering intermittent percussive ventilation to a patient having an airway and for use with an IPV device having a source of continuous gas flow and having a source of pulsed gases comprising a combination injector and exhalation valve assembly comprising a main body having an airway port for communication with the airway of the patient and having proximal and distal extremities and a flow passage extending from the proximal extremity to the distal extremity. The main body has a depending portion forming a plenum chamber in communication with the flow passage in the main body. A nebulizer is removably secured to the depending portion of the main body and has a nebulizer chamber in communication with the plenum chamber. The depending portion of the main body and the nebulizer form a handle adapted to be gripped by the hand of the patient holding the breathing head assembly.
