Compression of the heart as the result of buildup of blood or other fluid in the pericardial sac, leading to decreased cardiac output.
cardiac tamponade (pericardial tamponade)
An injury to the chest in which the skin is not broken, usually caused by blunt trauma.
closed chest injury
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.
commotio cordis
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.
flail chest
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.
flutter valve
The accumulation of blood and air in the pleural space of the chest.
hemopneumothorax
A collection of blood in the pleural cavity.
hemothorax
A bruise of the heart muscle.
myocardial contusion
A dressing made of Vaseline-impregnated gauze, aluminum foil, or plastic that protects a wound from air and bacteria.
occlusive dressing
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 chest injury
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.
open pneumothorax
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.
paradoxical motion
The fibrous sac that surrounds the heart.
pericardium
A partial or complete accumulation of air in the pleural space.
pneumothorax
Injury or bruising of lung tissue that results in hemorrhage.
pulmonary contusion
Any pneumothorax that is free from significant physiologic changes and does not cause drastic changes in the vital signs of the patient.
simple 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.
spontaneous pneumothorax
An open or penetrating chest wall wound through which air passes during inspiration and expiration, creating a sucking sound. See also open pneumothorax.
sucking chest wound
Increased respiratory rate.
tachypnea
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.
tension pneumothorax
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.
traumatic asphyxia
