Abstract :
Pulmonary surfactant physicochemistry is important in the proper mechanical function of the pulmonary system. Monolayer collapse and respreading are substantial contributors to the dynamic surface tension-area (S-A) loops. The authors compared experimental and theoretical studies of S-A behavior to discern the relevant physicochemistry in an oscillating bubble system. They found that secondary layer formation was highly dependent on the surfactant adsorption characteristics
