Abstract

A peritoneal dialysis system for performing peritoneal dialysis using a pre-determined total volume of dialysate and arranged to employ a plurality of therapy cycles comprising a fill phase in which dialysate is delivered from the dialysis system via a patient line, a dwell phase, and a drain phase in which fluid is drained via the patient line, the system comprising: at least one pump chamber controllable to move fluid; a patient line in fluid communication with the at least one pump chamber to receive dialysate from the at least one pump chamber for delivery and to deliver fluid to the at least one pump chamber; a plurality of valves to selectively control flow in flow channels of the dialysis system; and a control system arranged to control the dialysis system to perform the following: control the at least one pump chamber and the plurality of valves to deliver a first infusion volume of dialysate to the patient line as part of a therapy cycle; measure the first infusion volume of dialysate delivered to the patient line during the therapy cycle; control the at least one pump chamber and the plurality of valves to receive fluid from the patient line as part of the therapy cycle; measure a volume of fluid received from the patient line during the therapy cycle; estimate a volume of ultrafiltration fluid produced during the therapy cycle; estimate a volume of residual fluid for the therapy cycle based on the measured volume of fluid received, the estimated ultrafiltration fluid produced and the measured first infusion volume of dialysate delivered; determine a value for a maximum volume of fluid at the end of a dwell phase; and initiate a next therapy cycle if the estimated volume of residual fluid for the therapy cycle plus a volume of dialysate to be delivered for the next therapy cycle plus an estimated volume of ultrafiltration fluid produced for the next therapy cycle does not exceed the maximum volume of fluid at the end of a dwell phase.
