Claim 8:
9. A method, comprising:
receiving, by a processing system, hematocrit measurements corresponding to blood of a patient during hemodialysis treatment for the patient;
determining, by the processing system, an initial set of parameter values to be used with a two-compartment vascular refill model;
estimating, by the processing system, 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, by the processing system, 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.
