1. A hemodialysis machine comprising:
- at least one dialysate pump configured to move dialysate to a dialyzer;
a blood pump operable to move blood to the dialyzer;
a user/machine interface including(a) individually selectable digits zero through nine, and(b) a video screen; and
at least one processor, the processor and user/machine interface configured to(i) enable a cumulative ultrafiltration value to be entered via selection from the digits,(ii) enable a total time to be entered via selection from the digits, and(iii) enable a plurality of ultrafiltration values as steps over time forming a profile to be entered after entry of the cumulative ultrafiltration value and the total time;
(iv) display a shape of the entered profile on the video screen; and
(v) cause the entered cumulative ultrafiltration value to be removed via the dialyzer, within or over the entered total time, according to the entered profile.
