Term | Definition |
---|---|
cardiac tamponade (pericardial tamponade) | Compression of the heart as the result of buildup of blood or other fluid in the pericardial sac, leading to decreased cardiac output. |
closed chest injury | An injury to the chest in which the skin is not broken, usually caused by blunt trauma. |
commotio cordis | A blunt chest injury caused by a sudden, direct blow to the chest that occurs only during the critical portion of a person's heartbeat. |
flail chest | A condition in which two or more ribs are fractured in two or more places or in association with a fracture of the sternum so that a segment of the chest wall is effectively detached from the rest of the thoracic cage. |
flutter valve | A one-way valve that allows air to leave the chest cavity but not return; formed by taping three sides of an occlusive dressing to the chest wall, leaving the fourth side open as a valve. |
hemopneumothorax | The accumulation of blood and air in the pleural space of the chest. |
hemothorax | A collection of blood in the pleural cavity. |
myocardial contusion | A bruise of the heart muscle. |
occlusive dressing | A dressing made of Vaseline-impregnated gauze, aluminum foil, or plastic that protects a wound from air and bacteria. |
open chest injury | An injury to the chest in which the chest wall itself is penetrated by a fractured rib or, more frequently, by an external object such as a bullet or knife. |
open pneumothorax | An open or penetrating chest wall wound through which air passes during inspiration and expiration, creating a sucking sound; also referred to as a sucking chest wound. |
paradoxical motion | The motion of the portion of the chest wall that is detached in a flail chest; the motion—in during inhalation, out during exhalation—is exactly the opposite of normal chest wall motion during breathing. |
pericardium | The fibrous sac that surrounds the heart. |
pneumothorax | A partial or complete accumulation of air in the pleural space. |
pulmonary contusion | Injury or bruising of lung tissue that results in hemorrhage. |
simple pneumothorax | Any pneumothorax that is free from significant physiologic changes and does not cause drastic changes in the vital signs of the patient. |
spontaneous pneumothorax | A pneumothorax that occurs when a weak area on the lung ruptures in the absence of major injury, allowing air to leak into the pleural space. |
sucking chest wound | An open or penetrating chest wall wound through which air passes during inspiration and expiration, creating a sucking sound. See also open pneumothorax. |
tachypnea | Increased respiratory rate. |
tension pneumothorax | A life-threatening collection of air within the pleural space; the volume and pressure have both collasped the involved lung and caused a shift of the mediastinal structures to the opposite side. |
traumatic asphyxia | A pattern of injuries seen after a severe force is applied to the chest, forcing blood from the great vessels back into the head and neck. |
