體表面積(BSA)是人體表面的總面積，在確定藥物劑量（尤其是化療）以及校正心輸出量等生理指標時，往往比體重更為準確。本計算器使用兩種最常見的公式——Mosteller（簡單的平方根公式）與 Du Bois——根據您的身高與體重估算 BSA，並顯示其平均值。本工具僅供參考，臨床用藥劑量必須由醫療專業人員確認。
體表面積(BSA)在醫學中被廣泛用於確定化療藥物及其他藥物的劑量，以及對心輸出量進行校正。此結果為估算值，臨床決策應始終由醫療專業人員做出。
常見問題
- What is body surface area (BSA)?
- BSA is the total external surface area of the body, measured in square metres. It is widely used in medicine to scale drug doses, especially chemotherapy, and to express physiological values like cardiac index, since it tracks body size better than weight alone.
- How is BSA calculated?
- The Mosteller formula is BSA (m2) = the square root of (height cm x weight kg / 3600), a simple, widely used estimate. The Du Bois formula uses height and weight with exponents. Enter both measurements and the tool returns each result plus the average.
- What is a typical BSA value?
- The average adult BSA is about 1.7 m2, with most adults falling roughly between 1.5 and 2.0 m2 depending on height and weight. Different formulas can vary slightly, so clinical dosing usually specifies which formula to use.
