Abstract
Devices, systems, and methods for measuring the blood loss of a subject during a medical procedure. Blood and other fluids are received within a container, and a blood measurement device determines the hemoglobin concentration of the fluid within the container. The blood measurement device can also calculate the estimated blood loss of the subject based upon the determined hemoglobin concentration and the volume of the fluid within the container and the patient's hemoglobin.
