compute_bsa: Compute Body Surface Area (BSA)

Description

Computes BSA from height and weight making use of the specified derivation method

Usage

compute_bsa(height = height, weight = weight, method)

Value

The BSA (Body Surface Area) in m^2.

Arguments

height

HEIGHT value

It is expected that HEIGHT is in cm.

Permitted Values: numeric vector

weight

WEIGHT value

It is expected that WEIGHT is in kg.

Permitted Values: numeric vector

method

Derivation method to use:

Mosteller: sqrt(height * weight / 3600)

DuBois-DuBois: 0.20247 * (height/100) ^ 0.725 * weight ^ 0.425

Haycock: 0.024265 * height ^ 0.3964 * weight ^ 0.5378

Gehan-George: 0.0235 * height ^ 0.42246 * weight ^ 0.51456

Boyd: 0.0003207 * (height ^ 0.3) * (1000 * weight) ^ (0.7285 - (0.0188 * log10(1000 * weight)))

Fujimoto: 0.008883 * height ^ 0.663 * weight ^ 0.444

Takahira: 0.007241 * height ^ 0.725 * weight ^ 0.425

Permitted Values: character value

Details

Usually this computation function can not be used with %>%.
