Effect of Hydrostatic Pressure and Hematocrit on Blood Flow and Filtration Rate

  • Chapter
Arteriovenous Hemofiltration

Abstract

Arterial pressure and hematocrit are the practically important determinants of blood flow through capillaries [2, 3, 6, 7]. The following figures (except Fig. 5) demonstrate results of studies on the blood flow and filtration rate studied under in vivo conditions (37 °C) [9]; oxygen and glucose substituted blood [10]; pulsatile blood flow with Harvard-pump driven membrane heart [8] in relation to blood pressure, negative filtration pressure, hematocrit, use of three-way valves in the extracorporeal tubing system and in relation to postdilution [5]. The Amicon continuous arteriovenous hemofiltration (CAVH) set (1983) including diafilter-20 (0.2 m2) and the eight Charr-Vygon vascular catheters were used for the artificial circulation. Systolic, diastolic, and venous back flow pressure as well as the flow and pressure profiles were comparable to in vivo conditions.
