1. What is the DuBois BSA Calculator?

Definition: This calculator estimates body surface area (BSA) using the DuBois formula, which relates height and weight to BSA.

Purpose: It's widely used in medical fields for drug dosing, chemotherapy regimens, and physiological measurements.

2. How Does the Calculator Work?

The calculator uses the DuBois formula:

Where:

• \( BSA \) — Body Surface Area (square meters)
• \( W \) — Weight (kilograms)
• \( H \) — Height (centimeters)

Explanation: The formula provides an estimate of body surface area based on weight and height measurements.

3. Importance of BSA Calculation

Details: BSA is crucial for determining proper drug dosages, especially for chemotherapy, and for various medical assessments.

4. Using the Calculator

Tips: Enter weight in kilograms and height in centimeters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why use the DuBois formula?
A: It's the most widely validated BSA formula and has been used in medical practice since 1916.

Q2: How accurate is the DuBois formula?
A: It's generally accurate for adults but may be less precise for very obese or very lean individuals.

Q3: Are there alternative BSA formulas?
A: Yes, including Mosteller, Haycock, and Gehan-George formulas, but DuBois remains the gold standard.

Q4: When is BSA used in medicine?
A: For chemotherapy dosing, renal function assessment, burn evaluation, and cardiac index calculations.

Q5: How do I convert pounds to kg and inches to cm?
A: 1 kg = 2.2 lbs; 1 inch = 2.54 cm. We may add a converter in future versions.
