A computer-implemented method and system for estimating fluid loss. A graphical representation of a container is displayed. User inputs to display elements may include incrementing or decrementing sliding markers to desired set positions. A first user input may indicate a volume of a second fluid, and a second user input may indicate a total volume of fluid. A first volume of a first fluid may be estimated based on the first and second user inputs. A graphical representation of the first volume of the first fluid may be displayed as a fluid level within the graphical representation of the container. A second volume of the first fluid contained in an absorbent article may be estimated based on a difference between a dry weight and a wet weight measured on a scale. A quantity of the first fluid may be estimated based on the first and second volumes.

Disclosed is water-absorbent resin particles, in which a value of non-pressurization DW after 3 minutes is 14 ml/g or more, and a value of liquid suction power after 3 minutes measured by the following method is 11 ml/g or more. A liquid suction power measurement method: 0.3 g of the water-absorbent resin particles is uniformly dispersed in a cylindrical container having a mesh-like bottom and having an inner diameter of 26 mm; the cylindrical container is placed in a container containing 40 g of a physiological saline solution, the water-absorbent resin particles are caused to absorb the physiological saline solution for 30 minutes from the bottom of the cylindrical container, and thereby a swollen gel is obtained; and non-pressurization DW, which is measured in a state where another 0.3 g of the water-absorbent resin particles is uniformly dispersed on the swollen gel in the cylindrical container, is defined as liquid suction power.
