1. What is BSA Calculator for Burns?

Definition: This calculator estimates Body Surface Area (BSA) using the Mosteller formula, particularly useful for burn assessment and treatment.

Purpose: It helps medical professionals determine the extent of burns and calculate appropriate medication dosages based on body surface area.

2. How Does the Calculator Work?

The calculator uses the Mosteller formula:

Where:

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

Explanation: The product of weight and height is divided by 3600, and the square root of this value gives the body surface area.

3. Importance of BSA Calculation for Burns

Details: Accurate BSA estimation is crucial for determining burn severity (using the Rule of Nines), fluid resuscitation, and medication dosing in burn patients.

4. Using the Calculator

Tips: Enter the patient's weight in kilograms and height in centimeters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is BSA important for burn patients?
A: BSA helps estimate the percentage of body burned, which guides treatment decisions including fluid replacement and medication dosing.

Q2: How accurate is the Mosteller formula?
A: It's within 1-2% of more complex methods and is widely used in clinical practice for its simplicity and reliability.

Q3: When would I need this calculation?
A: For initial burn assessment, determining fluid resuscitation needs (Parkland formula), and calculating medication dosages.

Q4: Are there other BSA formulas?
A: Yes, including Du Bois, Haycock, and Gehan-George formulas, but Mosteller is most common for burn assessment.

Q5: How does this relate to the Rule of Nines?
A: The Rule of Nines divides the body into sections representing 9% or multiples of 9% of total BSA to estimate burn extent.
