Body Surface Area (BSA) is used in medicine to calculate drug doses, burn area, and cardiac output. The Mosteller formula is the most widely used due to its simplicity.

공식

Mosteller: BSA (m²) = √(Height(cm) × Weight(kg) / 3,600); DuBois: BSA = 0.007184 × H^0.725 × W^0.425

BSA: Body Surface Area (m²)
H: Height (cm)
W: Weight (kg)

2DuBois: BSA = 0.007184 × H^0.725 × W^0.425
3Boyd: accounts better for extremes of weight
4Normal adult BSA: approximately 1.7–1.9 m²

결과

BSA = √(175×70/3600) = √3.403 = 1.845 m²

자주 묻는 질문

Why is BSA used instead of weight for drug dosing?

BSA correlates better with physiological processes (metabolic rate, organ function) than weight alone.

What's the normal adult BSA range?

Typically 1.7–1.9 m². Average adult ≈ 1.8 m². Children much smaller proportionally.

Which formula should I use?

Mosteller is simpler and preferred in most modern clinical settings. DuBois and Boyd for specific populations.
