A combination spirometer or peak flow meter and nebulizer system is provided. Utilization of common elements, on a time sharing basis is accomplished by the combined instrumentation. The sharing of a common chamber by a peak flow meter and a nebulizer system is controlled by valves operated in response to phases of the respiratory process of a patient.
