Plasma exchange

In the case of plasma exchange, patient‘s blood-liquid (plasma) containing pathogenic substances, is exchanged with a protein-containing substitute fluid. In this process, the patient‘s blood flows through a plasma separator. It separates the plasma from the blood cells. Subsequently, the replacement liquid is supplied to the patient together with the previously separated blood cells. The method is used in a number of diseases in which the possibility for selective purification of the plasma exists.
