Membranes and filters for haemodiafiltration

Online haemodiafi ltration is an extracorporeal technique, utilizing highly permeable and highly biocompatible membranes, which permits the combination of convective and diffusive solute removal from the blood and offers increased removal of medium-weight uraemic solutes, compared to the more frequently used low- and high-fl ux haemodialysis. The objective of this chapter is to review the membranes and fi lters available for haemodiafi ltration and to discuss factors that infl uence their performance during clinical use.
