DIALYZER
A wide range of dialyzers is available. Dialyzers differ in the nature of the semipermeable membrane, permeability and method of sterilization. The dialyzer selected will influence the biocompatibility of the treatment. Performance characteristics are determined by the membrane permeability and the design of the dialyzer. The membrane permeability is generally indicated by the designation "low-flux" or "high-flux". High-flux membranes allow the passage of larger molecules and display a higher water permeability than low-flux membranes thus necessitating the use of machines with volumetric fluid control to ensure safe fluid removal.
The quality of the therapy provided is determined by the biocompatibility and performance characteristics of the dialyzer and the treatment parameters selected, e.g. treatment time or blood/dialysate flow.
