Abstract:
1. A method comprising: providing a hemodialysis machine comprising tubes to transfer blood between a patient and the machine, a display screen, and one or more controllers operable for: receiving a first value that represents a pre-dialysis body weight of a patient; receiving a second value that represents a volume of liquid (V) inside a body of the patient; administering a dialysis treatment to the patient; while the dialysis treatment is being administered to the patient: determining a dialyzer clearance (K) associated with the dialysis treatment; calculating, based at least in part on the length of time, the instantaneous body weight, the volume of liquid, and the dialyzer clearance, a urea reduction ratio (URR) associated with the dialysis treatment; providing a user interface for display on the display screen of the hemodialysis machine comprising: a set of controls that enable a user to control whether or not either of a URR value and a Kt/V value are presented on the display, and enabling the user to toggle between presentation of a Kt/V value and presentation of a URR value on the display, comprising a toggle control to enable toggling between a display of a URR value and a Kt/V value, and radio controls specifying whether the user interface displays one or both of Kt/V values and URR values,
