Feature of shock lung is
Diffuse alveolar damage
Usual interstitial infiltrates
Organizing pneumonia
Bronchiolitis
In ARDS, the presence of alveolar and interstitial fluid and the loss of surfactant can lead to a marked reduction of lung compliance. Without an increase in end-expiratory pressure, significant alveolar collapse can occur at end-expiration,with consequent impairment of oxygenation. Ref Davidson edition23rd pg 199
