Abstract:

We review three benchmark quantitative models for flow generation by physiological tube pumps. In each case significant differences between model predictions and tube behavior was emphasized. In order to close these gaps both modeler and Physiologist often the same investigator need to find paths which can grow to bridges. The modeler must develop more exact solutions to provide Physiologists with plug-in equations which will accept measurements. The Physiologist must make the kind of measurements which can be reasonably tested by a meaningful model. The measurements which have been features in this review are pressure, viscosity and geometry--or where geometry varies with time, kinematic data. A number of diagnostic marker formulas have been presented as stepping stones to modeling. These include R sub e, Beta, slenderness etc. which translates physiological data into indicators for modeling directions.
