Frequently asked questions
- What is the Mosteller formula?
- BSA (m²) = √(height in cm × weight in kg ÷ 3600). It is simple and accurate enough for most clinical purposes.
- Why is BSA used for drug dosing?
- BSA correlates better with organ size and cardiac output than weight alone, making it the preferred scaling factor for chemotherapy and many IV medications.
