This models the dynamic adsorption, desorption, and squeeze-out phenomena of an exogenous pulmonary surfactant (surfactant TA) solution surrounding an oscillating bubble. The influence of the alveolar surface tension on the concentration of the surfactant lining the alveolus can be simulated by this model describing the adsorption/desorption kinetics of a surfactant on a bubble and the change in surface tension generated. The volume of the bubble is driven in a sinusoidal manner.
The equations for this model may be viewed by running the JSim model applet and clicking on the Source tab at the bottom left of JSim's Run Time graphical user interface. The equations are written in JSim's Mathematical Modeling Language (MML). See the Introduction to MML and the MML Reference Manual. Additional documentation for MML can be found by using the search option at the Physiome home page.
