KIDNEY DIALYSIS

摘要

Methods are disclosed for providing operationial instructions to a hemodialysis circuit (10) having a dialysis filter (48) and a capability of operating according to a time-varying parameter such as variable ultrafiltration. According to the methods, entered are a desired time period, a target cumulative value of the parameter, such as target ultrafiltration volume, and a proposed time-varying profile of the parameter that is representable as a plot of coordinates in a region defined by an ordinate of values of the parameter and a time-based abscissa defining a profile cumulative value of the parameter. If the profile cumulative value is not equal to the target cumulative value, then the proposed time-varying profile is changed along the ordinate to make the cumulative values equal. The circuit (10) then operates according to the changed profile to achieve the entered target cumulative value within the time period.
