A cough or sneeze is usually preceded by a deep inspiration, frequently close to total lung capacity. This is initially followed by a forced expiration from a forceful contraction of the expiratory muscles against a closed glottis. This maneuver can cause intrapleural and airway pressure to momentarily rise to over 100 cmH2O above atmospheric pressure. Near the peak of the rise in intrapleural pressure, the glottis suddenly opens which results in an explosive expiration, with linear airflow velocities that may exceed 960 km per hour. When the glottis opens,
