Abstract

A variation of a method for estimating a quantity of a blood component in a fluid canister includes: within an image of a canister, identifying a reference marker on the canister; selecting an area of the image based on the reference marker; correlating a portion of the selected area with a fluid level within the canister; estimating a volume of fluid within the canister based on the fluid level; extracting a feature from the selected area; correlating the extracted featured with a concentration of a blood component within the canister; and estimating a quantity of the blood component within the canister based on the estimated volume and the concentration of the blood component within the canister.

Claims (8)

1. A method for assessment of blood within a canister, comprising:

at a processor, selecting an area of an image of the canister upon detection of a reference marker on the canister;

at the processor, determining a fluid level within the canister based upon the area within the image;

at the processor, generating an estimated volume of blood within the canister based on the fluid level;

at the processor, extracting a feature from at least one pixel of the area;

at the processor, correlating the feature with a concentration, of a blood component within the canister;

at the processor, estimating a quantity of the blood component within the canister based on the estimated volume and the concentration of the blood component within the canister; and

by way of the processor, rendering an analysis indicative of the quantity of the blood component and an estimated total patient blood loss, based upon the estimated volume of blood within the canister.
