A pulmonary contusion is a contusion (bruise) of the lung, caused by chest
trauma. As a result of damage to capillaries, blood and other fluids
accumulate in the lung tissue. The excess fluid interferes with gas
exchange, potentially leading to inadequate oxygen levels (hypoxia). Unlike
pulmonary laceration, another type of lung injury, pulmonary contusion does
not involve a cut or tear of the lung tissue. A pulmonary contusion usually
is caused by blunt trauma but also is caused by explosions or a shock wave
associated with penetrating trauma. With the use of explosives during World
Wars I and II, pulmonary contusion resulting from blasts gained recognition.
In the 1960s its occurrence began to receive wider recognition in civilians,
for whom it is usually caused by traffic accidents. Often nothing more than
supplemental oxygen and close monitoring is needed; however, intensive care
may be required. The severity ranges from mild to deadly—small contusions
may have little or no impact on the patient's health—yet pulmonary contusion
is the most common type of potentially lethal chest trauma. With an
estimated mortality rate of 14–40%, pulmonary contusion plays a key role in
determining whether an individual will die or suffer serious ill effects as
the result of trauma.
