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.  
🗑
