1. A method of estimating patient blood loss comprising:
receiving, by one or more processors, an image of at least a portion of a container with the image depicting blood and non-blood fluid being held in the container;
determining, by the one or more processors, a volume of the fluid held in the container;
determining, by the one or more processors, a color component value of a region of the image, the region depicting a portion of the fluid held in the container;
determining, by the one or more processors, a concentration of hemoglobin within the fluid based on the color component value of the region of the image; and
providing, by the one or more processors, an indication that quantifies the patient blood loss in the container based on the volume of the fluid held in the container and the concentration of the hemoglobin.
