1. An extracorporeal blood treatment system comprising:
extracorporeal blood treatment apparatus comprising one or more pumps and one or more sensors for use in performing an extracorporeal blood treatment, wherein the one or more pumps comprise an effluent pump to remove fluid from a patient during extracorporeal blood treatment according to a patient fluid removal rate; and
a computing apparatus comprising one or more processors and operatively coupled to the extracorporeal blood treatment apparatus, wherein the computing apparatus is configured to:
run the effluent pump to remove fluid from the patient based on the patient fluid removal rate during an extracorporeal blood treatment;
stop the effluent pump;
determine a patient fluid removal makeup volume in response to the stoppage of the effluent pump, wherein the patient fluid removal makeup volume is a volume of patient fluid that was not removed during the stoppage; and
increase the patient fluid removal rate in response to the stoppage of the effluent pump and the determination of the patient fluid removal makeup volume for use after the stoppage ceases, wherein increasing the patient fluid removal rate comprises increasing the patient fluid removal rate by a selected rate of fluid removal; and
re-start the effluent pump to run based on the increased patient fluid removal rate.
