  Acute respiratory distress syndrome (ARDS) is non-cardiogenic pulmonary edema that manifests as rapidly progressive dyspnea, tachypnea, and hypoxemia leading to respiratory failure reason is roughly one-half of intensive care units (ICUs). ARDS progresses through several phases after a direct pulmonary or indirect extrapulmonary insult. In the exudative phase, which may last seven to 10 days, alveolar macrophages secrete mediators that lead to the accumulation of inflammatory cells in the lung. In surfaces, pro-inflammatory mediators, and chemokines, this accumulation is released, leading to pathologic vascular permeability, gaps in the alveolar epithelial barrier, and necrosis of types I and II alveolar cells. Intravascular coagulation in the alveolar capillaries leads to microthrombi. Most cases of ARDS in adults are associated with pneumonia with or without sepsis (60%) or nonpulmonary sepsis (16%). The incidence of ARDS varies from 26 to 68 cases per 100,000 populati...
