pulmonary contusion 

A pulmonary contusion (or lung 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).

Pulmonary contusion should be assessed in primary survey of trauma patient.
