Answer

Endothelial injury in the pulmonary vasculature leads to disturbed capillary blood flow and enhanced microvascular permeability, resulting in interstitial and alveolar edema. Neutrophil entrapment within the pulmonary microcirculation initiates and amplifies the injury to alveolar capillary membranes. Acute lung injury and acute respiratory distress syndrome (ARDS) are frequent manifestations of these effects. Indeed, sepsis and pneumonia are the most common causes of ARDS.
