Chest Injuries

Chapter 27

QuestionAnswer
Closed Chest Injury An injury to the chest in which the skin is not broken, usually due to blunt trauma.
Dyspnea Difficulty breathing
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 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.
Hemoptysis The spitting or coughing up of blood
Hemothorax A collection of blood in the pleural cavity.
Myocardial Contusion A bruise of the heart muscle.
Occlusive dressing A dressing made of vaseline gauze, aluminum foil, or plastic that prevents air and liquids from entering or exiting a wound.
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.
Paradoxical Motion The motion of the portion of the chest all that is detached in a flail chest; the motion-in during inhalation, our during exhalation- is exactly the opposite of normal chest wall motion during breathing.
Pericardial Tamponade Compression of the heart due to a buildup of blood or other fluid in the pericardial sac.
Pericardium the fibrous sac that surrounds the heart.
Pnewmothorax An accumulation of air or gas in the pleural cavity.
Pulmonary contusion a bruise of the lung.
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.
tachypnea Rapid respirations
Tension Pneumothorax An accumulation of air or gas in the pleural cavity that progressively increases the pressure in the chest with potentially fatal results.
