Abstract
A system for monitoring blood distribution in a subject, the system comprising a processor(38) responsive to Doppler ultrasound data representing arterial blood flow in at least two different locations of the subject, such as the neck and the arm, to obtain velocity (C, B1, B2, B3) or volumetric flow rate at each location, to monitor changes in a predetermined function of the blood flows, and to provide an output indicative of the monitored changes which may result from blood volume centralization. This can indicate the onset of hypovolemia or hypervolemia.
