Fluid loss estimation of medical items

A computer-implemented method for quantifying amniotic fluid and blood from a patient, the method comprising:

• displaying on a display:
• a graphical representation of a container,
• a first display element,
• a second display element, and
• a third display element automatically selected from a group of display elements based on at least one of a procedure type, a previous procedure type, a selected brand of absorbent articles, and a user preference;
• receiving a first user input to the first display element on the display, wherein the first display element is configured to be incremented or decremented to a desired set position based on a fluid level of the amniotic fluid as observed in the container;
• receiving a second user input to a second display element on the display, wherein the second display element is configured to be incremented or decremented to a desired set position based on a fluid level of total fluid as observed in the container;
• receiving a third user input to the third display element on the display indicating a quantity of each different type of absorbent articles;
• displaying on the display graphical representations of the amniotic fluid and the total fluid within the graphical representation of the container;
• estimating a volume of amniotic fluid contained within the container based on the first user input;
• estimating a first volume of blood contained within the container based on the first user input and the second user input;
• receiving a predetermined dry weight associated with each of the different types of the absorbent articles from a memory device;
• estimating a total dry weight associated with the absorbent articles based on the third user input and the predetermined dry weight;
• estimating a second volume of blood contained in the absorbent article based on a difference between the total dry weight of the absorbent articles and a wet weight of the absorbent articles;
• estimating a quantity of blood based on the estimated first and second volumes of the blood;
• and
• displaying on the display the quantity of the blood.

A system for quantifying fluid from a patient, the system comprising:

• a display configured to display:
• a graphical representation of a container,
• a first display element for receiving a first user input indicating a volume of amniotic fluid observed in the container,
• a second display element for receiving a second user input indicating a total fluid volume observed in the container, and
• a third display element automatically selected from a group of display elements based on at least one of a procedure type, a previous procedure type, a selected brand, and a user preference, wherein a third user input to the third display element is for indicating a quantity of each different type of absorbent articles;
• a scale configured to measure a total wet weight of the absorbent articles;
• and
• a processor coupled to the scale and the display, wherein the processor is configured to:
• estimate a first volume of blood in the container based on the first and second user inputs;
• receive a predetermined dry weight associated with each type of the absorbent articles from a memory device;
• estimate a total dry weight associated with the absorbent articles based on the third user input and the predetermined dry weight;
• receive the total wet weight of the absorbent articles from the scale;
• estimate a second volume of blood in the absorbent articles based on a difference between the total dry weight and the total wet weight of the absorbent articles;
• and
• estimate a quantity of blood based on the estimated first and second volumes of the first fluid,
• wherein the display is configured to display graphical representations of the volume of amniotic fluid and the total fluid volume within the graphical representation of the container;
• and
• wherein the first and second display elements are sliding markers, the display is a touchscreen display configured to receive a touch input incrementing or decrementing the sliding markers to desired set positions, and the processor is configured to increment or decrement displayed fluid levels within the container to correspond to actual fluid levels within the container based on the first and second user inputs.
