Claim:
1. A method of performing a therapeutic blood component exchange procedure employing an automatic blood separating and processing device that includes a processor configured to be responsive to operator input of a selected one of a plurality of possible therapeutic blood component exchange procedures and to operate the blood separating and processing device to carry out of the selected exchange procedure, the method including: flowing blood from a patient to the blood separating and processing device; separating the blood into a plurality of blood components in a separator of the blood separating and processing device; returning to the patient fewer than all of the withdrawn plurality of separated blood components, at least one of the separated blood components being withheld from return by the blood separating and processing device in accordance with the selected therapeutic blood component exchange procedure; flowing to the patient a replacement fluid that is one of a cellular replacement fluid or a non-cellular replacement fluid; during the flowing of a replacement fluid changing from the one of the cellular replacement fluid or a non-cellular replacement fluid to the other of the cellular replacement fluid or a non-cellular replacement fluid; sensing the replacement fluid flowing to the patient; comparing, at the time of changing, the sensed replacement fluid to the selected therapeutic blood component exchange procedure; and flowing the replacement fluid to the patient only if the processor determines that the sensed replacement fluid is a proper replacement fluid for the selected therapeutic procedure at the time of changing.
