British statistics show an annual mortality rate of 1.26 and 0.62 deaths per million person-years in men and women, respectively. [15] A significantly increased risk of death is seen in older people and in those with secondary pneumothoraces, when the lung collapses due to another underlying health condition such as chronic lung disease .
An injury that is potentially more serious than pulmonary contusion, pulmonary laceration involves disruption of the architecture of the lung, [2] while pulmonary contusion does not. [3] Pulmonary laceration is commonly caused by penetrating trauma but may also result from forces involved in blunt trauma such as shear stress .
Flail chest is usually accompanied by a pulmonary contusion, a bruise of the lung tissue that can interfere with blood oxygenation. [5] Often, it is the contusion, not the flail segment, that is the main cause of respiratory problems in people with both injuries. [6] Surgery to fix the fractures appears to result in better outcomes. [7]
The water content of the lung increases over the first 72 hours after injury, potentially leading to frank pulmonary edema in more serious cases. [20] As a result of these and other pathological processes, pulmonary contusion progresses over time and can cause hypoxia (insufficient oxygen).
When the rib cage moves out, it no longer pulls the lungs with it. Thus the lungs cannot expand, the pressure in the lungs never drops and no air is pulled into the bronchi. Respiration is not possible. The affected lung, which has a great deal of elastic tissue, shrivels in what is referred to as a collapsed lung. [citation needed]

Pneumothorax occurs when there is air trapped between the lung and the chest wall; this can leave the patient's lung unable to fully inflate ("collapsed lung"). A bronchopleural fistula is when there is a tube-like opening that allows air to escape. [9] Minimally invasive surgery is beneficial for patient outcome, with reduced risk of ...
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 ] Typically chest injuries are caused by blunt mechanisms such as direct, indirect, compression, contusion, deceleration, or blasts [ 2 ] caused by ...
