Whatโ€™s a typical adult BSA?

Typical adult body surface area is roughly 1.6โ€“2.0 mยฒ.

What is BSA used for?

Itโ€™s used to calculate chemotherapy drug dosages, IV fluid volumes, and to normalize medical indices like cardiac index. Always follow your physicianโ€™s guidance for actual medical decisions.
