Calculate Body Surface Area (BSA)



Formula

The formula to calculate Body Surface Area (BSA) is:

\[ \text{BSA} = 0.007184 \times \text{Weight}^{0.425} \times \text{Height}^{0.725} \]

What is Body Surface Area (BSA)?

Body Surface Area (BSA) is a measure of the total surface area of the human body. It is used in various medical practices to calculate doses for chemotherapy, medication, and the amount of fluids to be administered intravenously. BSA is considered a more accurate measure of metabolic mass than body weight because it is less affected by abnormal adipose mass.

Example Calculation

Let's assume the following values:

Using the formula:

\[ \text{BSA} = 0.007184 \times 70^{0.425} \times 175^{0.725} \]

\[ \text{BSA} \approx 1.848 \text{ m²} \]

The Body Surface Area (BSA) is approximately 1.848 m².
