# What is the DuBois formula?

## What is the DuBois formula?

Du·Bois for·mu·la (dū-bwah’), a formula for predicting a person’s surface area from weight and height: A = 71.84W0.425 H0.725, where A = surface area in cm2, W = weight in kg, and H = height in cm.

What is BSA measurement?

Body Surface Area (BSA) BSA measures the total surface area of the body and is used to calculate drug dosages and medical indicators or assessments. The first formula was developed by Du Bois in 1916 and since then, several others have been developed.

### What is BSA m2?

Body surface area: BSA. The total surface area of the human body. Average body surface area for adult men: 1.9 m2. Average body surface area for adult women: 1.6 m2. Average body surface area for children (9 years): 1.07 m2.

Why do we need body surface area?

Body surface area is also useful to assess the degree of severity in severe burn injury patients. It is crucial to accurately assess the percentage of total body surface area that a patient has sustained burns to stratify the severity best and guide the management of patients with burn injuries.

## How do you calculate BSA manually?

BSA = 0.016667 × W0.5 × H0.5 Suppose the weight of a random person is 95.45 kg and his height is 190.5 cm, then multiplying these values and diving the resulting value with 3600, we get 5 and the square root of 5 is 2.24 m².

How do you calculate BSA height?

A formula to estimate the approximate surface area if height and weight be known….meters inches.

Body Surface Area
Formula : BSA (m2) =
Mosteller : = √ height (cm) x weight (kg) 3600
DuBois & DuBois : = 0.20247 x height (m)0.725 x weight (kg)0.425
Haycock : = 0.024265 x height (cm)0.3964 x weight (kg)0.5378

### How do you calculate BSA without height?

A formula to estimate the approximate surface area if height and weight be known. Arch Int Med 1916 17:863-71. Haycock GB, Schwartz GJ, Wisotsky DH….meters inches.

Body Surface Area
Formula : BSA (m2) =
Boyd : = 0.0003207 x height (cm)0.3 x weight (grams)0.7285 – (0.0188 x log(weight))

How do you find the BMI?

Body Mass Index is a simple calculation using a person’s height and weight. The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9.

## What is BSA vs BMI?

While Body Mass Index (BMI) is a measure of a person’s body fat mass, Body Surface Area measures the total surface area of a person’s body and is frequently used in order to calculate drug dosage and the amount of fluids to be administered by IV.
