Claim 14:
15. A method of processing blood using a cell washing system comprising a reusable processing machine having a touch screen, at least one pump and a panel, the cell washing system further comprising a disposable fluid circuit configured to be loaded on the panel, comprising:
receiving from the touch screen user input data for a plurality of protocols for storage in a memory of the reusable processing machine, each protocol comprising values for a set of process parameters for a wash procedure, wherein the user input data received from the touch screen comprises a numeric value for one of the process parameters for one of the protocols;
storing the one of the protocols having the numeric value in the memory of the reusable processing machine;
receiving an identifier from a user via the touch screen of the reusable processing machine;
determining if the identifier permits the user to modify the prestored protocol;
receiving a modification of the prestored protocol from the user via the touch screen based on the determination, wherein the modification comprises a modification of the numeric value,
permitting control of the reusable processing machine based on a plurality of authorizations comprising at least an administrator authorization and a second authorization, the second authorization being a default;
receiving a password from the touch screen;
comparing the password to a password stored in the memory of the reusable processing machine;
if the received password matches the password stored in the memory, determining that the password is associated with an administrator authorization;
applying a received command to change the setting, wherein it is assumed as a default that the user has the second authorization unless the user attempts to enter a password, at which point it is determined if the user has the administrator authorization, the administrator authorization being the authorization that permits the user to change the setting;
receiving the disposable fluid circuit on the panel of the reusable processing machine; and
processing the blood employing a wash procedure using the modified protocol and using the changed setting, wherein the processing comprises separating red blood cells from the blood to remove free hemoglobin.
