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.

Abstract: The disclosed subject matter relates to extracorporeal blood processing or other processing of fluids. Volumetric fluid balance, a required element of many such processes, may be achieved with multiple pumps or other proportioning or balancing devices which are to some extent independent of each other. This need may arise in treatments that involve multiple fluids. Safe and secure mechanisms to ensure fluid balance in such systems are described.

Abstract: A patient's body temperature measurement may be made by varying the heat transfer dynamics of a fluid exiting the patient's body and fitting parameters of heat transfer configuration to measurements under the varied conditions. Then the input temperature of the patient core can be extracted from the model and a current temperature measurement remote from the patient core and optionally other measurements such as fluid flow rate.
