Abstract:

In this study, maximum expiratory and inspiratory pressures and the resulting lung-volume changes were simultaneously recorded at ground level approximately 747 mm. Hg and at 30,000-feet-pressure altitude 225 mm. Hg. For given pulmonary pressures, lung-volume changes were greater at 30,000 feet than at ground level. The area of the maximum pressure-volume diagram at 30,000 feet was 79 of the area of the same diagram at ground level. Author
