Methods and systems for characterizing fluids from a patient

A computer-implemented method for characterizing fluids from a patient, the method comprising:

• receiving a time series of images of a conduit configured to receive the fluids from the patient;
• receiving conduit-related information associated with the conduit;
• identifying a conduit image region in the time series of images;
• estimating a volumetric flow rate of the fluids in the conduit based on time series of images and the conduit-related information;
• estimating a concentration of a blood component of the fluids passing through the conduit;
• estimating a volume of blood passing through the conduit based on the estimated concentration of the blood component and the estimated volumetric flow rate;
• and
• updating, on a display, a total blood loss based on the estimated volume of blood.

A computer-implemented method for characterizing fluids from a patient, the method comprising:

• receiving a time series of images of a conduit configured to receive the fluids from the patient;
• identifying an optical fiducial in at least one image of the time series of images;
• determining at least one of a conduit-related information, an assigned color value, and a spatial position associated with the optical fiducial;
• identifying a conduit image region in the time series of images;
• estimate a volumetric flow rate of the fluids in the conduit based on the time series of images;
• estimating a concentration of a blood component of the fluids passing through the conduit;
• estimating a volume of blood passing through the conduit based on the estimated concentration of the blood component and the estimated volumetric flow rate;
• and
• updating, on a display, a total blood loss based on the estimated volume of blood.
