Abstract
Blood is conveyed from a source into a separator, which separates at least one target blood component from the blood. The target blood component is then conveyed out of the separator, with the procedure continuing until an initial target amount of blood to be processed has been conveyed from the source into the separator and the target blood component separated from the initial target amount of blood to be processed has been conveyed out of the separator as an actual yield of the target blood component. An adjusted target amount of blood to be processed is then determined based at least in part on the difference between a target yield of the target blood component and the actual yield. The initial target amount of blood to be processed is then replaced with the adjusted target amount of blood to be processed when next executing the procedure.
