Mosteller and Du Bois BSA from height and weight.

BSA is used for drug dosing and, in breast reduction, the Schnur sliding scale relates BSA to the minimum resection weight per breast at the 22nd percentile — a common proxy for medical necessity. The estimate shown is interpolated from the published 22% table. Always defer to the patient's own insurer or local Schnur table. Education only.

Mosteller BSA

1.82

√((height × weight) / 3600)

Du Bois BSA

1.81

0.007184 × height^0.725 × weight^0.425

Schnur minimum resection / breast

456 g

22nd-percentile threshold at 1.82 m² (Mosteller BSA)

体表面积(BSA)

体表面积估算身体外部的总面积,被广泛用于标准化药物剂量和生理参数。Mosteller 公式最为简便;Du Bois 则是经典的替代方案。

Mosteller 与 Du Bois

Mosteller BSA = √((身高 cm × 体重 kg) / 3600)。Du Bois BSA = 0.007184 × 身高^0.725 × 体重^0.425。两者对典型成年人给出的数值相近。

BSA 与乳房缩小术(Schnur 量表)

在乳房缩小术中,Schnur 滑动量表将 BSA 与每侧乳房的最小切除重量相关联,常用于医学必要性标准。请使用你当地或保险方的 Schnur 表来确定克数阈值。
