如何计算Body Surface Area Calculator
learn.whatIsHeading
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.
分步指南
- 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
例题解析
输入
Adult male: 80 kg, 180 cm
结果
BSA ≈ 2.0 m²
Average adult male BSA is 1.9 m²
输入
Child: 20 kg, 110 cm
结果
BSA ≈ 0.76 m²
BSA scales non-linearly with size
