A number of improvements relating to methods and apparatuses for kidney dialysis are disclosed. These include checking of dialysate bypass status using flow measurement; using a flow sensor to confirm the absence of ultrafiltration during bypass; automatic testing of ultrafiltration function by removal of a discrete volume from a portion of the dialysate flow path coupled with a pressure test of that part of the flow path; using a touch screen user interface; bar graph profile programming of ultrafiltration, sodium, and bicarbonate parameters; using a RAM card to upload treatment instructions to, and to download treatment data from, the machine; automatic setting of proportioning mode (acetate or bicarbonate) based on connections of concentrate lines; predicting dialysate conductivity values based on brand and formulation of concentrates; minimizing no-flow dead time between dialysate pulses; initiating operation in a timed mode from a machine power-off condition; preserving machine mode during machine power-fail condition; calibration scheduling and reminding; automatic level adjusting; and blood leak flow rate detecting.

A method of programming a time-varying parameter in a process-control system, the method comprising the steps: (a) providing a touch screen interface; (b) displaying on the touch screen first and second axes, the first axis corresponding to the time-varying parameter, the second axis corresponding to time; (c) touching the touch screen at a plurality of points to define points on a parameter-versus-time curve; (d) presenting on the touch screen a series of bars corresponding to said curve; (e) selecting one of said bars for alteration; (f) displaying on the screen a numeric parameter corresponding to the selected bar; (g) touching the screen at first or second locations to increase or decrease, respectively, the displayed numeric parameter and thereby alter the value of the numeric parameter to which the selected bar corresponds; (h) touching the screen at a third location to signify completion of steps (b)-(g); and (i) storing data corresponding to the bars in a memory to which the process-control system can refer in changing the time-varying parameter with time.
