ARDS Definition: It is a nonspecific pulmonary condition characterized by abnormal permeability of pulmonary capillary endothelium leading to progressive accumulation of fluid within the lung parenchyma & alveoli. Clinical Features:- Progressive hypoxia, tachypnea, dyspnea, cough, sputum production & air hunger Restlessness, confusion, somnolence and coma Tachycardia, cyanosis, hypotension, Haemodynamic instability, shock, and cold extremities. Hypoxia, hypercarbia, decreased lung compliance, pneumonia, decreased breath sounds, wheezing and rhonchi.
Respiratory failure Multisystem organ failure. Investigations: Chest X-Ray: Pneumonia & atelectasis Increased pulmonary vascularity, interstitial infiltration, opacities, white out of lung fields & loss of lung volume. Arterial blood gas Analysis: Increased Paco2 Decreased Pao2 Decreased pH Alveolar-Arterial oxygen gradient (A-ao2)…
