The lung contusion (dt. Lung contusion ) is a complication of the chest trauma . The lungs are squeezed as a result of the force exerted on the chest, which usually results in diffuse bleeding into the lung parenchyma . The resulting reduced blood flow in the alveoli increases the functional dead space so that the affected tissue no longer takes part in the gas exchange.

Pulmonary contusion often results in pulmonary edema and, if left untreated, can be fatal .
