Answer

Adhesive atelectasis results from surfactant deficiency. Surfactant normally reduces the surface tension of the alveoli, thereby decreasing the tendency of these structures to collapse. Decreased production or inactivation of surfactant leads to alveolar instability and collapse. This is observed particularly in acute respiratory distress syndrome (ARDS) and similar disorders.
