体表面积(BSA)是人体表面的总面积，在确定药物剂量（尤其是化疗）以及校正心输出量等生理指标时，往往比体重更为准确。本计算器使用两种最常见的公式——Mosteller（简单的平方根公式）和 Du Bois——根据您的身高和体重估算 BSA，并显示其平均值。本工具仅供参考，临床用药剂量必须由医疗专业人员确认。
体表面积(BSA)在医学中被广泛用于确定化疗药物及其他药物的剂量，以及对心输出量进行校正。此结果为估算值，临床决策应始终由医疗专业人员做出。
常见问题
- 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.
