WebSurfactant prevents alveolar collapse at low lung volume, and preserves bronchiolar patency during normal and forced respiration (biophysical functions). In addition, it is … WebThe administration of exogenous surfactant either via a bronchoscope or nebulizer may reduce surface tension within alveoli and prevent cyclical collapse, improving oxygenation, and ameliorating VILI. Multiple administrations appear necessary due to the neutralization of surfactant by edema fluid.
