Understanding Body Surface Area
Body Surface Area (BSA) is used in medicine to calculate drug dosages, determine cardiac output, and assess various physiological parameters. The average adult BSA is 1.7-1.9 m².
Chemotherapy drugs are often dosed per m² of BSA. The Du Bois formula is most commonly used in clinical practice, while Mosteller is preferred for its simplicity.
