First Claim
1. A non-transitory computer-readable storage medium with an executable program stored thereon comprising instructions that, when executed by one or more programmable computer systems incorporated into a blood fluid removal device, cause the blood fluid removal device to execute the following steps:
- acquire first patient data of a first blood fluid removal session regarding one or more of (i) one or more patient physiological parameters; and
(ii) time since a last blood fluid removal session before an upcoming blood fluid removal session;
acquire data regarding one or more target outcomes of each blood fluid removal session;
compare the data regarding the at least one of the target outcomes of each blood fluid removal session to corresponding data regarding at least one prior patient outcome stored in a lookup table;
wherein the lookup table comprises data regarding system parameters used in the one or more prior blood fluid removal sessions of the patient and comprises prior patient data prior to a first session regarding one or more of (i) one or more patient physiological parameters and (ii) time since the prior blood fluid removal session before a corresponding upcoming blood fluid removal session;
compare the first patient data to the corresponding prior patient data stored in the lookup table;
initiate the upcoming blood fluid removal session employing the system parameters used in the prior blood fluid removal session if the at least one of the one or more target outcomes is within a predetermined range of the corresponding data regarding the at least one prior patient outcome stored in the lookup table and the patient data is within a predetermined range of the corresponding prior patient data.

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 patent parameters. By comparing the patient'"'"'s current parameters to past parameters in response 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.

2. A method carried out by a blood fluid removal system,
wherein the blood fluid removal system comprises: -
(a) a blood fluid removal medium to remove blood from the patient, wherein the blood enters the medium, a fluid contained in the blood is removed from the blood, and the blood exits the medium; (b) one or more control elements to control (i) a rate at which the medium removes fluid from the blood or (ii) concentration of electrolytes or pH in the blood that exits the medium; (c) one or more sensors to monitor one or more physiological parameters of the patient wherein the physiological parameters are one or more selected from the group consisting of blood pressure, heart rate, pH, and electrolyte concentration, the one or more sensors sensing signals from one or more of the blood and a tissue of the patient; and (d) control electronics comprising memory and a processor, wherein the control electronics are in operable communication with the one or more sensors and are operably coupled to the one or more control elements, wherein the control electronics are programmed to carry out the method, comprising; acquiring first patient data of a first blood fluid removal session regarding one or more of;
(i) the one or more patient physiological parameters; and
(ii) time since a last blood fluid removal session before an upcoming blood fluid removal session;acquiring data regarding one or more target outcomes of each blood fluid removal session; comparing the data regarding at least one of the one or more target outcomes of each blood fluid removal session to corresponding data regarding at least one prior patient outcome stored in a lookup table, wherein the lookup table comprises data regarding system parameters used in the one or more prior blood fluid removal sessions of the patient and comprises prior patient data prior to the first session regarding one or more of (i) one or more patient physiological parameters; and
(ii) time since the prior blood fluid removal session before a corresponding upcoming blood fluid removal session;comparing the first patient data to the corresponding prior patient data stored in the lookup table; initiating the upcoming blood fluid removal session employing the system parameters used in the prior blood fluid removal session if the at least one of the one or more target outcomes is within a predetermined range of the corresponding data regarding the at least one prior patient outcome stored in the lookup table and the patient data is within a predetermined range of the corresponding prior patient data stored in the lookup table. - View Dependent Claims (3, 4, 5, 6, 7, 8)
