1. What is the Mosteller Formula?

The Mosteller formula is a mathematical equation used to estimate body surface area (BSA) from height and weight measurements. It is one of the most commonly used formulas in clinical practice due to its simplicity and accuracy.

2. How Does the Calculator Work?

The calculator uses the Mosteller formula:

\[ BSA = \sqrt{\frac{Height \times Weight}{3600}} \]

Where:

\( Height \) — Height in centimeters (cm)
\( Weight \) — Weight in kilograms (kg)
\( BSA \) — Body Surface Area in square meters (m²)

Explanation: The formula calculates the square root of the product of height and weight divided by 3600, providing an estimate of body surface area.

3. Importance of BSA Calculation

Details: Body surface area is used in various medical applications including drug dosing (especially chemotherapy), fluid management, burn assessment, and physiological measurements. Accurate BSA calculation helps ensure proper medication dosage and treatment planning.

4. Using the Calculator

Tips: Enter height in centimeters, weight in kilograms. Both values must be valid positive numbers. The calculator will compute the body surface area in square meters.

5. Frequently Asked Questions (FAQ)

Q1: Why use the Mosteller formula instead of other BSA formulas?
A: The Mosteller formula is widely accepted, simple to calculate, and has been validated in numerous clinical studies. It provides results comparable to more complex formulas.

Q2: What are typical BSA values for adults?
A: Average BSA for adult men is about 1.9 m², for adult women about 1.6 m². Values typically range from 1.4-2.2 m² depending on body size.

Q3: When is BSA measurement most important?
A: BSA is crucial for chemotherapy dosing, pediatric drug calculations, burn surface area assessment, and determining cardiac index.

Q4: Are there limitations to this formula?
A: Like all BSA formulas, Mosteller provides an estimate. It may be less accurate in extreme body types, obesity, or pediatric populations where other formulas might be preferred.

Q5: Can this calculator be used for children?
A: Yes, the Mosteller formula can be used for both adults and children, though some clinicians prefer age-specific formulas for pediatric patients.
