[Transcapillary fluid exchanges. A program in Basic].

Transcapillary fluid exchanges are analysed with the Wiederhielm's model programmed in this study in Basic language. The physiological variable which are taken in account are: arterial and venous capillary pressures, interstitial pressure and the colloid osmotic pressure of plasma and tissue proteins. This model shows the relationship between filtration, reabsorption, plasma leakage and the lymph flow. Edema resulting from venous and lymphatic obstruction or from a decrease in plasma oncotic pressure are simulated.
