Abstract: The disclosed total blood volume determination systems and methods provide for a faster, simpler, more practical, less invasive, and more flexibly deployable device for blood volume measurement. These systems and methods are based on measuring, in a patient's bloodstream, the resonance of an agent injected into the circulating blood that allows for assessment of the agent's concentration and determination of the total blood volume. The agent may take a variety of forms, including an agent that is detectable via a non-invasive technique such as ultrasound. The agent may be measured over time and fitting the measurement data to provide an accurate determination of total blood volume.
