Airflow patterns were recorded during voluntary coughs to help determine how biological aerosols are transmitted between passengers in a confined space such as an airplane cabin. Coughs from both healthy men and women and men and women with obstructive lung disease were analyzed. The groups were selected based on the results of spirometry tests performed at the pulmonary clinic of West Virginia University Hospital. Airflow was measured and recorded during three consecutive cough maneuvers for each subject and the maximum airflow, average airflow and maximum gas acceleration were evaluated. Results showed that airflow parameters during a series of coughs were significantly altered by obstructive lung disease.
