Choice of Apheresis Therapy
Therapeutic plasma exchange volume is usually 1–1.5 times the patient’s plasma volume.
Selection of a plasma fractionator (second filter) for double filtration plasmapheresis (DFPP) depends on the size of the pathogenic substance.
Evaluating the adsorption affinity of the pathogen will enhance the efficacy of immunoadsorption therapy.
A plasma separator (first filter) should not be used for hemodialysis.
