# bsa: Estimate body surface area In physiology: Calculate physiologic characteristics of awake and anesthetized adults, children and infants

## Description

Estimate body surface area (BSA)

## Usage

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19``` ```bsa_adult(height_m, weight_kg, ...) bsa_dubois_dubois(height_m, weight_kg, ...) bsa_mosteller(height_m, weight_kg, ...) bsa_haycock(height_m, weight_kg, ...) bsa_gehan_george(height_m, weight_kg, ...) bsa_boyd(height_m, weight_kg, ...) bsa_fujimoto(height_m, weight_kg, ...) bsa_takahira(height_m, weight_kg, ...) bsa_shuter_aslani(height_m, weight_kg, ...) bsa_schlich(height_m, weight_kg, male, ...) ```

## Arguments

 `height_m` height(s) in meters `weight_kg` numeric vector of weight(s) in kg `...` passed to validation `male` logical value(s) whether patient is male. TRUE or FALSE.

## Details

1.73 m^2 is commonly used as an average adult BSA.

## Value

numeric vector of body surface areas in m^2.

## Functions

• `bsa_adult`: Uses 'bsa_mosteller()'

• `bsa_dubois_dubois`: Du Bois and Du Bois formula (usually the preferred formula for adults and children)

• `bsa_mosteller`: Mosteller formula

• `bsa_haycock`: Haycock formula

• `bsa_gehan_george`: Gehan and George formula

• `bsa_boyd`: Boyd formula

• `bsa_fujimoto`: Fujimoto formula (often used for Japanese individuals)

• `bsa_takahira`: Takahira formula (a variant of Du Bois that could be used for Japanese individuals; Fujimoto may be preferred)

• `bsa_shuter_aslani`: Shuter and Aslani formula

• `bsa_schlich`: Schlich formula
