When theabdominal surface is concave and tight the thoracic surfacemust be convex. This is the physiological position andindicates that the thorax is a vacuum. When the abdominalsurface of the diaphragm is convex it indicates that air,gas or liquid is in the thoracic cavity. Air may enter thepleural cavity through an external wound or followingrupture of bronchi, alveoli and the visceral pleura. Gasmay form in the thorax from the actio
