Abstract
A computer system may implement a method of calculating the generation rate of a substance in a dialysis patient, e.g. urea, creatinine or beta-2-microglobulin, based on data for one or more treatment sessions of intermittent dialysis therapy. The computer system obtains a concentration value (Cs) for the substance in the blood of the dialysis patient at the start of a treatment session, and a standard Kt/V value (stdKt/V) for the substance over a predefined time period (t), which includes the one or more treatment sessions. The computer system then computes the generation rate (G; G/V) as a function of stdKt/V, the first blood concentration value (Cs) and the predefined time period (t).

A computer-implemented method of calculating a generation rate of a substance in a dialysis patient, said method comprising:
- electronically obtaining a first concentration value for the substance in the blood of the dialysis patient at the start of a treatment session of intermittent dialysis therapy;
- electronically obtaining a standard Kt/V value for the substance over a predefined time period that includes the treatment session;
- and
- electronically calculating the generation rate of the substance in the dialysis patient as a function of the standard Kt/V value, the first concentration value and the predefined time period.
A non-transitory, computer-readable medium storing instructions, which when executed by a processor, cause the processor to:
- receive a first concentration value for a substance in the blood of the dialysis patient at the start of a treatment session of an intermittent dialysis therapy;
- receive a standard Kt/V value for the substance over a predefined time period that includes the treatment session;
- and
- calculate the generation rate of the substance in the dialysis patient as a function of the standard Kt/V value, the first concentration value and the predefined time period.
A system for calculating a generation rate of a substance in a dialysis patient comprising:
- a diaysis mahine including:
- a memory;
- and
- a processor in communication with the memory, the processor configured to:
- receive a first concentration value for the substance in the blood of the dialysis patient at the start of a treatment session of an intermittent dialysis therapy performed by the dialysis machine,
- receive a standard Kt/V value for the substance over a predefined time period that includes the treatment session, and
- calculate the generation rate of the substance in the dialysis patient as a function of the standard Kt/V value, the first concentration value and the predefined time period.
