Assignee: FRESENIUS MEDICAL CARE HOLDINGS, INC.
Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 16:
17. A non-transitory processor-readable medium having processor-executable instructions stored thereon, wherein the processor-executable instructions, when executed, facilitate:
receiving hematocrit measurements corresponding to blood of a patient during hemodialysis treatment for the patient;
determining an initial set of parameter values to be used with a two-compartment vascular refill model;
estimating values of one or more parameters for the patient based on the hematocrit measurements, the initial set of parameter values, and the two-compartment vascular refill model; and
outputting the estimated values for the patient;
wherein estimating the values of the one or more parameters for the patient based on the hematocrit measurements, the initial set of parameter values, and the two-compartment vascular refill model further comprises:
performing a parameter identification;
solving model equations using the initial set of parameter values to determine whether the two-compartment vascular refill model fits the hematocrit measurements; and
in response to determining that the two-compartment vascular refill model does not fit the hematocrit measurements, modifying the initial set of parameter values.
