Main article:
1.Hemodialysis.
In hemodialysis ,the patients blood is pumped through the blood compartment of a dialyzer,exposing it to a partially permeable membrane.the dialyzer is composed of thousands of tiny synthetic hollow fibers.The fiber wall acts as the semi-permeable membrane.Blood flows through the fibers,dialysis solution flows around the outside of the fibers,and water and wastes move between these two solution.
The cleansed blood is then returned via the circuit back two the body.Ultrafiltration occurs by increasing the hydrostatic pressure across the dialyzer membrane.This usually is done by applying a negative pressure to the dialysate compartment of the dialyzer.This pressure gradient causes water and dissolved solutesto move from blood to dialysate,and allows the removal of several litres of excess fluid during a typical 3 to 5 hour treatment.
