Abstract:
1. A device for monitoring and controlling renal replacement therapy, said device comprising a computer that communicates with at least one pulse oximeter/photoplethysmography probe, said computer comprising at least one processing module; a first computer-readable program code module that causes said computer to separate a signal stream from said at least one pulse oximeter/photoplethysmography probe into an isolated pulsatile cardiac component signal stream, an isolated venous capacitance component signal stream, or both; a second computer-readable program code module that causes said computer to analyze said isolated pulsatile cardiac component signal stream and/or said isolated venous capacitance component signal stream to determine changes in blood flow, blood volume status, or both; and a third computer-readable program code module that causes said computer to adjust said renal replacement therapy, without need for user input, in response to a change in said isolated pulsatile cardiac component signal stream and/or said isolated venous capacitance component signal stream, whereby said therapy is adjusted until said isolated pulsatile cardiac component signal stream and/or said isolated venous capacitance component signal stream is modulated to a target level.
