摘要
Blood collection systems and methods minimize citrate toxicity in donors. The systems and methods convey whole blood at a prescribed rate Qb 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 EqQBCIR, where: IMAGE where: CIR is a selected nominal a-symptomatic citrate infusion rate (in mg/kg/min or equivalent), AC is a selected anticoagulant ratio, Wgt is the donor's weight (in kg or equivalent), and CitrateConc is the citrate concentration in the anticoagulant (in mg/ml or equivalent).
