| has gloss | eng: A pulmonary laceration is a chest injury in which lung tissue is torn or cut. An injury that is potentially more serious than pulmonary contusion, pulmonary laceration involves disruption of the architecture of the lung, while pulmonary contusion does not. that result from different rates of acceleration or deceleration of different tissues of the lung. Pulmonary laceration may result from blunt and penetrating forces that occur in the same injury and may be associated with pulmonary contusion. Lacerations of the lung tissue can also occur by compression of the alveoli against the ribs or spine. In type 1 lacerations, which occur in the mid lung area, the air-filled lung bursts as a result of sudden compression of the chest. The shearing stress in type 2 results when the lower chest is suddenly compressed and the lower lung is suddenly moved across the vertebral bodies. |
