Abstract Most commercially available aerosol generators for medical applications produce aerosols characterized by a broad particle size distribution and a large mass median (MMD). The desirable size of therapeutic and diagnostic aerosols is about 2-4 micrometers MMD with a narrow and uniform distribution. The size enhances testing reproducibility and the evaluation of drug efficacy. Researchers combined the commercially available DeVilbiss 65 nebulizer with a mixing/dilution chamber developed in the laboratory. The characteristics of this aerosol generator system (AGS) were examined over a range of operating conditions and concentrations of solutions of three bronchoconstrictive agents, histamine, carbachol and methacholine. The AGS produced a polydispersed aerosol with a MMD range of 1.7 to 2.4 micrometers and a Sg 1.5. The reliable and reproducible operation of the AGS greatly increases the power of bronchial challenge tests with bronconstrictive drugs.
