ABSTRACT:
Blood separation systems and methods employ a rotating chamber. The chamber includes an inlet region where whole blood enters for centrifugal separation into packed red blood cells, a plasma constituent, and an interface carrying mononuclear cells between the packed red blood cells and the plasma constituent. The packed red blood cells in the chamber have a hematocrit value H.sub.PRBC. A controller operates in a first mode to convey whole blood into the inlet region while removing packed red blood cells and the plasma constituent from the chamber and while maintaining the interface within the chamber. The controller also operates in the first mode to maintain a set H.sub.PRBC by conveying packed red blood cells into the inlet region.
