Abstract
A method of processing blood establishes communication between a donor and a blood flow path and pumps whole blood from the donor into a container through the blood flow path. The method centrifugally separates the whole blood in the container into concentrated red blood cells and a plasma constituent. After the method interrupts communication between the donor and the blood flow path, the method pumps the concentrated red blood cells from the container to mix the concentrated red blood cells with a nutritive solution to restore the hematocrit of the concentrated red blood cells to a desired value. The method also removes the plasma constituent.
