The deposition rate of aerosols during breath holding at different degrees of lung inflation was determined in lung emphysema patients, with or without chronic bronchitis, to determine the effect of alveolar wall destruction and the resultant enlargement of air spaces occurring in these patients. Lung volume at which the breath is held was determined with a "bag in a box" device provided with a system of valves; total lung capacity and residual volume were also determined. The results obtained in diseased and normal individuals demonstrate that determination of aerosol deposition in the lung during breath holding is a promising diagnostic procedure.
