Retrofiltration rates in high-flux hollow fiber hemodialyzers: analysis of clinical data

Clinical data obtained with high-flux hollow fiber hemodialyzers operating under the condition of zero net volume flow of filtrate are analyzed theoretically to obtain information about the profile of the radial volume flow density, the concentration of an impermeable solute along the axis of the ho...

Description
Summary:Clinical data obtained with high-flux hollow fiber hemodialyzers operating under the condition of zero net volume flow of filtrate are analyzed theoretically to obtain information about the profile of the radial volume flow density, the concentration of an impermeable solute along the axis of the hollow fibers, and the extent of retrofiltration. This information is of practical interest. The clinical data refer to dialyzers differing only in the diameter of the hollow fibers.
