Compute Body Surface Area (BSA)

Source: R/derive_param_bsa.R
compute_bsa.Rd

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

Usage 

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

Arguments

height

HEIGHT value

It is expected that HEIGHT is in cm.

Permitted values

numeric vector

Default value

height

weight

WEIGHT value

It is expected that WEIGHT is in kg.

Permitted values

numeric vector

Default value

weight

method

Derivation method to use:

Mosteller: sqrt(height * weight / 3600)

DuBois-DuBois: 0.007184 * height ^ 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

Default value

none

Value

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