Abstract
A method of estimating blood loss of patient fluid within a fluid canister. A camera may automatically capture one or more images of the fluid canister based on a detected change in volume of patient fluid within the fluid canister exceeding a threshold. The image is analyzed determine the volume of the patient fluid, and a blood concentration of the patient fluid within the fluid canister. The blood loss is estimated based on the volume and the blood concentration, and displayed on a display. A pixel-based height of the patient fluid within the fluid canister may be calculated based on the surface of the patient fluid. The pixel-based height may be converted to the estimated fluid volume. The image may be a frame of a multi-frame video feed. The image(s) of the multi-frame video feed may be analyzed as the patient fluid is being drawn into the fluid canister.
