Veterinary Body Surface Calculator

Veterinary BSA Formula:

\[ BSA = 0.101 \times W^{\frac{2}{3}} \]

Body Surface Area (m²):

Definition: This calculator estimates the body surface area (BSA) of animals based on their weight using the Meeh formula.

Purpose: It helps veterinarians determine medication dosages, nutritional requirements, and other physiological parameters.

The calculator uses the formula:

\[ BSA = 0.101 \times W^{\frac{2}{3}} \]

Where:

Explanation: The formula relates body surface area to body weight through a power function, as surface area scales with the 2/3 power of volume.

Details: Accurate BSA estimation is crucial for proper drug dosing, metabolic rate calculations, and nutritional planning in veterinary medicine.

Tips: Enter the animal's weight in kilograms. The weight must be > 0. The calculator is most accurate for mammals between 1-100 kg.

Q1: What animals is this calculator suitable for?
A: Primarily for mammals. Different constants may be needed for birds or reptiles.

Q2: Why use BSA instead of weight for dosing?
A: Many physiological processes correlate better with surface area than weight.

Q3: How accurate is this formula?
A: It provides a good estimate for most clinical purposes, but individual variation exists.

Q4: Should I round the BSA value?
A: For medication dosing, round to 2 decimal places for practical use.

Q5: Are there species-specific formulas?
A: Yes, some species may require adjusted constants (e.g., 0.1 for dogs, 0.09 for cats).
