Abstract
A patient fluid removal compensation volume may be determined to make up for the patient fluid removal that does not occur during machine down times, and the patient fluid removal rate may be increased until the compensating volume is satisfied.
Claims29
1-14. (canceled)
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:
- determine a patient fluid removal makeup volume in response to stoppage of the effluent pump, wherein the patient fluid removal makeup volume is a volume of patient fluid removal that did not occur during the stoppage;
- and
- increase the patient fluid removal rate in response to stoppage of the effluent pump 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 related to mass of the patient in response to an increased patient fluid removal makeup volume.

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:
- determine a patient fluid removal makeup volume in response to stoppage of the effluent pump, wherein the patient fluid removal makeup volume is a volume of patient fluid removal that did not occur during the stoppage;
- and
- increase the patient fluid removal rate in response to stoppage of the effluent pump for use after the stoppage ceases,
- wherein increasing the patient fluid removal rate comprises increasing the patient fluid removal rate by a selected percentage in response to an increased patient fluid removal makeup volume.

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:
- determine a patient fluid removal makeup volume in response to stoppage of the effluent pump, wherein the patient fluid removal makeup volume is a volume of patient fluid removal that did not occur during the stoppage;
- and
- increase the patient fluid removal rate in response to stoppage of the effluent pump for use after the stoppage ceases,
- wherein increasing the patient fluid removal rate comprises using a patient fluid removal rate value, wherein the patient fluid removal rate value comprises one or more of:
- a selected percentage patient fluid removal rate increase;
- a selected rate of fluid removal related to mass of the patient fluid removal rate increase;
- and
- a rate based on blood flow rate.
