Abstract
Apparatuses and methods for measuring total blood volume with ultrasound are disclosed. In one embodiment, a system for monitoring a blood volume of a patient includes an ultrasound transmitter configured for emitting an ultrasound toward a target blood vessel of the patient; and an ultrasound receiver configured for receiving the ultrasound reflected from the target blood vessel of the patient. The system also includes, a controller configured for: determining an expanded state of the blood vessel based on the ultrasound reflected from the target blood vessel; determining a collapsed stated of the blood vessel based on the ultrasound reflected from the target blood vessel; and determining the blood volume of the patient based on the ratio of the collapsed stated and the expanded stated of the blood vessel.
