A method and system for noninvasive determination of blood viscosity and hematocrit to optimize prehospital correction of hypovolemia is addressed. The method is based on studies of pulse wave propagation patterns in major arteries. Analytical relationships were obtained which allow blood viscosity and hematocrit to be determined. A technique was developed for noninvasive real-time monitoring of blood viscosity and hematocrit directly within the vascular bed. The features of the implementation of the proposed methodology and the principle of operation of the system are discussed.
