Body surface area (BSA) is a measurement of the total surface area of a person's body. It is used in a variety of medical calculations, such as determining drug dosages and fluid requirements. BSA can be calculated using a variety of methods, but the most common method is the Du Bois formula.
The Du Bois formula is based on a person's height and weight. To use the Du Bois formula, you will need to know a person's height in centimeters and their weight in kilograms. Once you have this information, you can use the following formula to calculate their BSA:
BSA (m2) = 0.007184 * Weight(kg)0.425 * Height(cm)0.725
