Response to Blunt Chest Injury: A New Experimental Model

Pulmonary insufficiency continues to be a major cause of death following trauma of many types. In combat casualties, direct injury to the lung is the most common cause of arterial hypoxemia, though contusion of the chest wall by a high velocity bullet may actually produce a greater pulmonary injury than when the lung is penetrated. Similarly, the familiar civilian injuries that occur when the chest is crushed against the steering wheel may produce severe contusion of the underlying pulmonary parenchyma while the chest wall remains intact. An experimental method for producing a standard injury to the lung through the intact chest wall was developed, and the acute changes in cardiopulmonary function following injury have been studied. The physiologic changes associated with healing of the injury were documented.
