Abstract
A parameter for controlling an inlet pump speed in a hemofiltration system is derived from fitting a line to multiple data points of pressure versus pump speed. The pressure is measured in a channel connecting an inlet pump to an outlet pump. First, the inlet pump operates and the pressure is sampled until it is stabilized, then the inlet pump speed is increased and pressure is measured to obtain a data point. Subsequently the inlet pump speed is decreased and pressure is measured to obtain another data point. A line is fit through the data points to obtain the parameter.
