What is BSA?
Body Surface Area estimates total skin surface area. Essential for drug dosing, burn assessment, and metabolic calculations in medical practice.
Formula Selection
Dubois is most common in clinical practice, Mosteller is simplest, and Haycock is preferred for pediatric patients.
Medical Applications
Used for chemotherapy dosing, burn treatment planning, cardiac output calculations, and metabolic rate estimations.
Dubois Formula
BSA = 0.007184 × height^0.725 × weight^0.425
Mosteller Formula
BSA = √((height × weight) / 3600)
Haycock Formula
BSA = 0.024265 × height^0.3964 × weight^0.5378
