Chest
Most penetrating injuries are chest wounds and have a mortality rate (death rate) of under 10%. Penetrating chest trauma can injure vital organs such as the heart and lungs and can interfere with breathing and circulation. Lung injuries that can be caused by penetrating trauma include pulmonary laceration (a cut or tear) pulmonary contusion (a bruise), hemothorax (an accumulation of blood in the chest cavity outside of the lung), pneumothorax (an accumulation of air in the chest cavity) and hemopneumothorax (accumulation of both blood and air). Sucking chest wounds and tension pneumothorax may result.
Penetrating trauma can also cause injuries to the heart and circulatory system. When the heart is punctured, it may bleed profusely into the chest cavity if the membrane around it {the pericardium) is significantly torn, or it may cause pericardial tamponade if the pericardium is not disrupted. In pericardial tamponade, blood escapes from the heart but is trapped within the pericardium, so pressure builds up between the pericardium and the heart, compressing the latter and interfering with its pumping. Fractures of the ribs commonly produce penetrating chest trauma when sharp bone ends pierce tissues.

Famous quotes containing the word chest:
“Are you there, Africa with the bulging chest and oblong thigh? Sulking Africa, wrought of iron, in the fire, Africa of the millions of royal slaves, deported Africa, drifting continent, are you there? Slowly you vanish, you withdraw into the past, into the tales of castaways, colonial museums, the works of scholars.”
—Jean Genet (1910–1986)
“There is hardly an American male of my generation who has not at one time or another tried to master the victory cry of the great ape as it issued from the androgynous chest of Johnny Weissmuller, to the accompaniment of thousands of arms and legs snapping during attempts to swing from tree to tree in the backyards of the Republic.”
—Gore Vidal (b. 1925)
“It was obvious that the size of your chest was in direct proportion to the size of your salary.”
