A contusion manifests initially as a hemorrhage followed by alveolar and interstitial edema.The edema can remain rather localized in the contused area or can spread to other lung areas.Inflammation affects alveolar-capillary units.As more units are affected by inflammation,further pathophysiologic events can occur,including decreased compliance,increased pulmonary vascular resistance,and decreased pulmonary blood flow.These processes result in a ventilation-perfusion imbalance that results in progressive hypoxemia and poor ventilation over a 24- to 48-hour period.
