Dialysis schedules that would yield sf-Kt/V values of over 20 for varying body weights of the patient at constant K (K = 180 mL/min). Each line shows the schedule that would yield an sf-Kt/V value of 20. The area above this line represents the dialysis times/frequencies that yield sf-Kt/V values of over 20. As the body weight of the patient increases, the dialysis time/frequency needed to obtain an sf-Kt/V value of over 20 increases. Thus, the optimal dialysis schedule depends on the patient’s body weight
