Acute lung injury results in damage to the alveolar epithelium and/or the pulmonary capillary endothelium causing fluid leakage from blood vessels into the interstitium and alveoli leading to impaired gas exchange. The ensuing hypoxemia‚ hypercarbia‚ and the compromise of oxygen delivery to tissues‚ leads to

Frequent infections inflame the lining and the layer of epithelium and also attract white blood cells‚ which release enzymes in order to move out of the blood and into the airways. These enzymes then digest parts of the lining of the lungs‚ so elastic tissue in the lining of the lungs is damaged. When this happens
