2 Fibroproliferative ( or proliferative) stage: Connective tissue and other structural elements in the  Uncontrolled ARDS can progress to an irreversible fibro-proliferative phase characterized by fibrosis of the lung parenchyma. II. Diagnostic Confirmation: Are you  The pulmonary pathologic features of acute respiratory distress syndrome (ARDS ) The exudative and proliferative phases have the greatest impact on the  Later, there is proliferation of alveolar epithelium and fibrosis, constituting the fibro-proliferative phase. Causes of ARDS may involve direct or indirect lung injury. Then, in the proliferative phase, there is organization of exudates and development of fibrosis.

Fibrotic phase: Phase of ARDS that occurs within hours or days of direct or indirect lung injury.

Marked disruption of acinar architecture leads to emphysema-like changes, with large bullae. The three phases of ARDS are the inflammatory, proliferative and fibrotic phases. i. The inflammatory phase occurs within the first 72 hours.

The proliferative phase is complete when the diseased lung becomes characterized by dense, fibrous tissue. Phase (Minutes to hours) Chronic Proliferative Phase (5 – 7 days) Recovery Pulmonary endothelial and alveolar epithelial injury permeability edema Surfactant dysfunction Maladaptive repair with mesenchymal cells and proliferative fibroblasts Alveolar edema and proteins are cleared, endothelial and epithelial injury repaired Acute hypoxemia, OBJECTIVE: Acute respiratory distress syndrome (ARDS) is a common diseases in critical ill patients, which is an acute-onset hypoxic condition with radiographic bilateral lung infiltration. And it can be divided into two phases in pathophysiology: an acute exudative phase combining diffuse alveolar damage and lung edema followed by a later fibro proliferative phase.
