1. A method carried out by a blood fluid removal system, comprising:
- initiating a blood fluid removal session, using a blood fluid removal device, with initial system parameters;
acquiring a first set of data regarding one or more patient physiological parameters, wherein the one or more patient physiological parameters include at least one of pH and concentration of an electrolyte;
storing the first data set in a most effective to date data set memory;
associating the initial system parameters in an increased effectiveness lookup table with the first data set;
adjusting at least one parameter of the blood fluid removal session by adjusting the blood fluid removal system to arrive at adjusted system parameters;
acquiring a second set of data regarding the one or more patient physiological parameters after the at least one parameter of the blood fluid removal session has been adjusted; and
determining which of the first and second set of data includes at least one value closer to a target value;
storing in the increased effectiveness lookup table data regarding the data set having at least one value closer to the target value; and
associating data regarding the adjusted system parameters with the data set having at least one value closer to the target value; and
repeating the process beginning with acquiring a first set of data regarding one or more patient physiological parameters;
storing the first data set in a least effective to date data set memory;
associating the initial system parameters in a decreased effectiveness lookup table with the first data set prior to adjusting the at least one parameter of the blood fluid removal session;
determining which of the first and second set of data includes at least one value further from the target value;
storing in the decreased effectiveness lookup table data regarding the data set having at least one value further from the target value; and
associating data regarding the adjusted system parameters with the data set having at least one value further from to the target value;
replacing the data in the least effective to date data set with the data from the data set having at least one value further from the target value; and
continuing the blood fluid removal session with the system parameters in the most effective to date data set;
wherein the blood fluid removal system performs at least one blood fluid removal process selected from the group consisting of ultrafiltration, hemofiltration, hemodialysis, hemodiafiltration and peritoneal dialysis.

Abstract
Methods for monitoring patient parameters and blood fluid removal system parameters include identifying those system parameters that result in improved patient parameters or in worsened patient parameters. By comparing the patient'"'"'s past responses to system parameters or changes in system parameters, a blood fluid removal system may be able to avoid future use of parameters that may harm the patient and may be able to learn which parameters are likely to be most effective in treating the patient in a blood fluid removal session.
