Body Surface Area (BSA) is the measured or calculated surface area of a human body. It is used in clinical medicine to calculate drug doses (particularly chemotherapy), burn area assessment, and metabolic rate estimation. BSA is considered more accurate than body weight alone for drug dosing.
Panduan Langkah demi Langkah
- 1Mosteller formula: BSA = √(H × W / 3600) — simple and widely used
- 2DuBois formula: BSA = 0.007184 × H^0.725 × W^0.425 — original 1916 formula
- 3Haycock formula: BSA = 0.024265 × H^0.3964 × W^0.5378 — most accurate for children
- 4H = height in cm, W = weight in kg, result in m²
