Understanding Body Surface Area (BSA) and Its Clinical Importance
Body Surface Area (BSA) is a crucial measurement in medical practice, representing the total surface area of the human body. Unlike body mass index (BMI), BSA provides more accurate dosing calculations for medications, chemotherapy, and burn assessment.
Why BSA Matters in Healthcare
Medical professionals use BSA calculations to determine proper drug dosages, particularly for medications with narrow therapeutic indices. It's essential for:
- Chemotherapy drug dosing
- Burn injury assessment
- Pediatric medication calculations
- Renal function evaluations
Calculating BSA Accurately
The Mosteller formula (used in this calculator) is widely accepted: BSA (m²) = √[(Height(cm) × Weight(kg))/3600]. Other methods include the DuBois and Haycock formulas, but Mosteller offers simplicity and accuracy.
