1. A hemodialysis apparatus comprising:

  • (a) a dialysate-delivery system for supplying dialysate to a hemodialyzer, the dialysate-delivery system comprising at least one unit selected from the group consisting of (i) a dialysate-preparation unit, (ii) a dialysate-circulation unit, (iii) an ultrafiltrate-removal unit, and (iv) a dialysate-monitoring unit; and

    (b) a user/machine interface operably connected to the dialysate-delivery system, the user/machine interface comprising a touch screen that (i) displays information corresponding to a setting of a first parameter pertinent to operation of the hemodialysis apparatus, the touch screen being operable to display a first indicium permitting the user to perform, using the touch screen, at least one step of a procedure for changing the setting of the first operational parameter, and to display a first time-variable profile of the first operational parameter, the first profile being representable as a plot of coordinates, the plot being with respect to an ordinate of values of the first operational parameter and a time-based abscissa; and

    (ii) is operable to display a second indicium permitting the user to perform, using the touch screen, at least one step of a procedure for changing a setting of a second operational parameter, and to display a second time-variable profile of the second operational parameter, the second profile being representable as a plot of coordinates, the plot being with respect to an ordinate of values of the second operational parameter and a time-based abscissa;

    wherein the first indicium and the second indicium are displayed simultaneously on a first screen of the touch screen; and

    wherein at least one of the first and second operational parameters is used to operate at least one of (i) the dialysate-preparation unit, (ii) the dialysate-circulation unit, (iii) the ultrafiltrate-removal unit, and (iv) the dialysate-monitoring unit.
