Abstract
A blood purification apparatus includes a blood circuit that allows a patient's blood to extracorporeally circulate; a blood purifier between the arterial blood circuit and the venous blood circuit having a blood flow route through which the blood extracorporeally flows and a dialysate flow route through which dialysate flows, the blood flow route and the dialysate flow route being separated from each other by a blood purification membrane; an ultrafiltration unit that filters out water from the blood in the blood flow route through the blood purification membrane and drains the water through the dialysate flow route; and a substitution-fluid supply unit that supplies substitution fluid. The blood purification apparatus includes a plasma-flow-rate-acquiring unit that acquires a plasma flow rate or a correlation value of plasma flow rate with reference to a blood concentration detected from the patient's blood and a plasma total protein detected from the blood.
