Abstract
An extracorporeal blood processing system having a centrifugal rotor, a control system, a plurality of peristaltic pumps, and a removable tubing circuit wherein blood components can be processed. A pump-balancing process, implemented by the control system, causes selected pumps to fill and empty a reservoir in the tubing circuit. Ratios of displaced volume per pump revolution or other pumping action can be used by the control system to increase the effectiveness and efficiency of the donation process. The pump-balancing process may be performed during priming or set-up of the blood processing system or during an actual donation.
