During this phase there is an influx of neutrophils, monocytes, lymphocytes and fibroblast proliferation as part of the inflammatory response. 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. of ARDS/DAD [12].

Although ARDS frequently culminates in "interstitial" fibrosis, the organization of intraluminal exudate dominates the histologic picture in the proliferative phase and establishes the framework for subsequent fibrous remodeling of the lung. In the proliferative phase, type II cells multiply to reconstitute the alveolar lining and an interstitial inflammatory infiltrate of mononuclear cells is accompanied by proliferation of fibroblasts. All these conditions are present 4 to 7 days after the insult, and the patient usually dies … The acute phase of ARDS is characterised by injury to the alveolar–capillary barrier, with disruption leading to increased permeability (‘leakiness’).

Exudative phase. Duration The respiratory symptoms of ARDS usually start within 6–72 hours after an eliciting risk factor and progress rapidly.
