What is BSA?
Body Surface Area (BSA) is a measurement of the total surface area of the human body. It's crucial for determining appropriate medication dosages, especially in chemotherapy, and for various physiological calculations.
Clinical Applications
- Chemotherapy dosing
- Cardiac index calculations
- Burn assessment
- Renal clearance studies
- Metabolic rate calculations
Formula Comparison
Most Common: Du Bois Formula
BSA = 0.007184 × W^0.425 × H^0.725
Simplified: Mosteller Formula
BSA = √(W × H / 3600)
Note: Normal adult BSA ranges from 1.5 to 2.0 m². Average adult BSA is approximately 1.7 m².
