BSA_livingstons_calculation v.0.1.0
The Livingston formula is a mathematical equation used to estimate an individual's body surface area (BSA) based on their weight and height. BSA is an important metric in clinical contexts, especially for calculating appropriate drug dosages, fluid requirements, and other physiological assessments.
To calculate estimated BSA using the Livingston's formula, aiding in clinical decisions such as medication dosing and treatment planning.
Use to estimate BSA in all patients weighing more than 10 kg, including obese patients. Use is less precise in small children weighing less than 10 kg. The formula, BSA (m2) = 0.1173 × Wt(kg)^0.6466, uses only patient's weight.
Not to be used for calculating BSA based on other formulas.
