Pulmonary laceration is a common result of penetrating trauma but may also be caused by blunt trauma; broken ribs may perforate the lung, or the tissue may be torn due to shearing forces [5] that result from different rates of acceleration or deceleration of different tissues of the lung. [6]
A chest injury, also known as chest trauma, is any form of physical injury to the chest including the ribs, heart and lungs.Chest injuries account for 25% of all deaths from traumatic injury. [1]
When lacerations fill with blood, the result is pulmonary hematoma, a collection of blood within the lung tissue. [3] Contusion involves hemorrhage in the alveoli (tiny air-filled sacs responsible for absorbing oxygen), but a hematoma is a discrete clot of blood not interspersed with lung tissue. [ 4 ]
Traumatic cardiac arrest (TCA) is a condition in which the heart has ceased to beat due to blunt or penetrating trauma, such as a stab wound to the thoracic area. [1] It is a medical emergency which will always result in death without prompt advanced medical care.
A pneumatocele results when a lung laceration, a cut or tear in the lung tissue, fills with air. [4] A rupture of a small airway creates the air-filled cavity. [1] Pulmonary lacerations that fill with blood are called pulmonary hematomas. [4] In some cases, both pneumatoceles and hematomas exist in the same injured lung. [5]

When the alveoli of the lung are ruptured, as occurs in pulmonary laceration, air may travel beneath the visceral pleura (the membrane lining the lung), to the hilum of the lung, up to the trachea, to the neck and then to the chest wall. [9]
Lacerations – irregular tear-like wounds caused by some blunt trauma. Lacerations and incisions may appear linear (regular) or stellate (irregular). The term laceration is commonly misused in reference to incisions. [9] Abrasions (grazes) – superficial wounds in which the topmost layer of the skin (the epidermis) is scraped off.
