Abstract
A processing system includes a processor including a separator, a set configured to cooperate with the separator to separate whole blood into plasma and other components, the set including an inlet line attachable to a patient to receive whole blood and an return line attachable to a patient to return processed fluid, and a source of replacement fluid connected to the disposable set, the processor configured to combine the other components with replacement fluid to define the processed fluid. The processor includes a controller and an input device coupled to the controller, the controller configured to receive an input via the input device, the input representing a volume of replacement fluid, and to control the processor to separate whole blood passing through the set and to combine the other components with the replacement fluid according to the input until the source of replacement fluid is empty.
