1. A method, comprising:
- initiating a blood fluid removal session of a patient with an initial blood fluid removal rate;
monitoring an indicator of tissue fluid volume of the patient during the blood fluid removal session;
monitoring an indicator of blood fluid volume of the patient during the blood fluid removal session;
determining a first indicator of tissue fluid volume and a first indicator of blood fluid volume;
acquiring a first set of data regarding the physiological health of the patient;
altering the rate of blood fluid removal to a second blood fluid removal rate;
determining a second indicator of tissue fluid volume and a second indicator of blood fluid volume;
acquiring a second set of data regarding the physiological health of the patient;
determining a preferable outcome measure based on the first and second sets of physiological data; and
altering the rate of blood fluid removal so that an indicator of tissue fluid volume and an indicator of blood fluid volume are within a pre-determined range of the preferable outcome measure.

Abstract
A method includes initiating a blood fluid removal session of a patient; monitoring an indicator of tissue fluid volume of the patient, or a portion thereof, during the blood fluid removal session; monitoring an indicator of blood fluid volume of the patient during the blood fluid removal session; determining whether a ratio of the indicator of tissue fluid volume to indicator of blood fluid volume is outside of a predetermined range; and altering the rate of fluid removal during the blood fluid removal session if the ratio is determined to be outside of the predetermined range. A blood fluid removal system may be configured to carry out the method.

13. A method carried out by a blood fluid removal system comprising:
-
initiating a blood fluid removal session of a patient; monitoring an indicator of tissue fluid volume of the patient, or a portion thereof, during the blood fluid removal session; monitoring an indicator of blood fluid volume of the patient during the blood fluid removal session; determining whether the indicator of tissue fluid volume and the indicator of blood fluid volume are outside of a predetermined range; and altering the rate that replacement fluid is added to the blood if the indicator of tissue fluid volume or the indicator of blood volume is determined to be outside of the predetermined range. - View Dependent Claims (14, 15, 16, 17, 18)
