Larger contusions have been correlated with a need for ventilation for longer periods of time. [15] Pulmonary contusion or its complications such as acute respiratory distress syndrome may cause lungs to lose compliance (stiffen), so higher pressures may be needed to give normal amounts of air [4] and oxygenate the blood adequately. [33]
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]
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.
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 ...
Bruises often become more prominent as time lapses, resulting in additional size and swelling, and may grow to a large size over the course of the hours after the injury that caused the bruise was inflicted. Condition and type of tissue: In soft tissues, a larger area is bruised than would be in firmer tissue due to ease of blood to invade tissue.
The sudden impact on the thorax causes an increase in intrathoracic pressure. [4] In order for traumatic asphyxia to occur, a Valsalva maneuver is required when the traumatic force is applied. [6]
The body responds to traumatic injury both systemically and at the injury site. [16] This response attempts to protect vital organs such as the liver, to allow further cell duplication and to heal the damage. [17] The healing time of an injury depends on various factors including sex, age, and the severity of injury. [18]
Scapular fracture is associated with pulmonary contusion more than 50% of the time. [8] Thus when the scapula is fractured, other injuries such as abdominal and chest trauma are automatically suspected. [1] People with scapular fractures often also have injuries of the ribs, lung, and shoulder. [4]
