Blood processing systems and methods which monitor citrate return to the donor

摘要

Blood collection systems and methods minimize citrate toxicity in donors. The systems and methods convey whole blood at a prescribed rate Q. sub.b into a separation device for separation into red blood cells and a plasma constituent. The systems and methods add anticoagulant including citrate to the whole blood. The systems and methods control Qb (in ml/min or equivalent) based upon a citrate equivalent blood flow rate EqQB.sub. CIR, where: ##EQU1## where: CIR is a selected nominal a- symptomatic citrate infusion rate (in mg/kg/min or equivalent),P PAC is a selected anticoagulant ratio,PPWgt is the donor's weight (in kg or equivalent), andPP CitrateConc is the citrate concentration in the anticoagulant (in mg/ml or equivalent).
