কীভাবে Body Surface Area গণনা করবেন
Body Surface Area কি?
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.
সূত্র
Mosteller: BSA (m²) = √(Height(cm) × Weight(kg) / 3,600); DuBois: BSA = 0.007184 × H^0.725 × W^0.425

175cm, 70kg (Mosteller)

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