Classification of artificial membrane used for blood purification therapy  Artificial membranes are classified based on the following categories: a) Biocompatibility b) Membrane Surface Area c) Molecular weight cutoff d) Ultrafiltration Coefficient e) Mass transfer Coefficient f) Clearance a) Biocompatibility:    Something that is biocompatible will not trigger a response from the body’s immune system. When blood touches a foreign substance, immune cells rush
