CONVECTIVE MASS TRANSFER OF METABOLITES IN DIALYZERS
Abstract
One of the parameters determining the effectiveness of blood purification using
membrane mass transfer device is a convection of low- and mediummolecular substances in the
blood composition, through the semi permeable membrane. The paper presents an analysis of
the contribution of convective mass transfer during hemodialysis, hemofiltration and hemodiafiltration;
the analytical expressions distribution of metabolites in the dialyzer and the clearance
of each of these procedures; calculated from the analytical expressions obtained clearances
compared with the rated values.
