The "Prometheus" liver support system is a 4008H hemodialysis device combined with the "FPSA" option. In addition to hemodialysis (HD) it allows for the extracorporeal removal of toxins from the blood in the event of acute or chronic hepatic failure. After the fractionation of the plasma, the primarily albumin-bound toxins are eliminated by means of an albumin-permeable capillary membrane filter on special adsorbers (FPSA - Fractionated Plasma Separation and Adsorption).

The integrated citrate/calcium unit allows the regional anticoagulation of the patient's blood in the extracorporeal circuit (primary and secondary
circuit) during an FPSA treatment or a hemodialysis treatment.
