The BSA Compare function lets you enter a body surface area and choose a demographic (above) to compute the percent compared to the mean.

Wallace Rule of Nines: This computes a percentage of the human body for burn victims based on percentages allocated to different body parts.

Rule of Fives: This computes a percentage of the human body for obese burn victims.

Parkland Replacement Fluid: This compute the volume of replacement fluids needed in the first 24 hours based on the patients weight (mass) and the percent of their body that has been burned.

BSA Percent: This computes a body surface area based on the total body surface area and a percent..
