Abstract:
Acute Respiratory Distress Syndrome (ARDS) is defined by bilateral diffuse infiltrates on chest radiography, a PO2/FiO2 ratio < 200, and noncardiogenic pulmonary edema. Pathophysiologically it is characterized by disruption of the alveolar lining and capillary endothelium, alveolar edema, protein exudation coupled with a marked inflammatory response and subsequent fibrosis and a resultant ventilation-perfusion mismatch. Effective treatment strategies include low tidal volume ventilation with positive end expiratory pressure, careful fluid management and good supportive care.

Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
