Abstract

A peritoneal dialysis ('PD') system includes a PD fluid pump; a patient line for receiving used PD fluid pumped by the PD fluid pump during a patient drain; a pressure sensor positioned and arranged to sense a negative pressure associated with the PD fluid pumped during the patient drain; and a control unit configured to (i) determine or know a flowrate of the PD fluid pumped during the patient drain, (ii) determine an applied negative pressure at which the PD fluid pump is to pump the PD fluid during the patient drain, the applied pressure based on a pressure drop corresponding to the determined or known flowrate, and (iii) use sensed negative pressure from the pressure sensor to cause the PD fluid pump to pump the PD fluid during the patient drain at the applied negative pressure.
