Membranas en terapias depurativas continuas

Abstract

The possibility of filtering water and solutes from the blood is conditioned by the nature of the filter membranes in purification techniques. Some important characteristics such as its surface, its hydrophilicity, its adsorptive capacity, among others, are described here.

Not all patients respond equally to all types of membrane, and it is necessary to know why. Perhaps a specific pathology needs a specific membrane. The Sieving coefficient help to know the depuration of the molecules. The calculation of the membrane permeability in convective treatments helps to assess how much surface is left free for the depuration.
