1. What is BSA Calculator Halls UK?

Definition: This calculator estimates body surface area (BSA) using the Haycock formula, which is commonly used in the UK medical practice.

Purpose: BSA calculations are essential for determining medication dosages, chemotherapy regimens, and various clinical assessments.

2. How Does the Calculator Work?

The calculator uses the Haycock formula:

\[ BSA = 0.024265 \times W^{0.5378} \times H^{0.3964} \]

Where:

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

Explanation: The formula provides a more accurate BSA estimation than simpler methods, especially for pediatric and obese patients.

3. Importance of BSA Calculation

Details: Accurate BSA measurements are crucial for proper drug dosing, nutritional assessments, and burn management in clinical settings.

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 use Haycock formula instead of DuBois?
A: Haycock formula is more accurate for children and non-average body types, while DuBois may underestimate BSA in these cases.

Q2: What's the typical BSA range for adults?
A: Average BSA is about 1.7 m² for adult men and 1.6 m² for adult women, but varies with body size.

Q3: When is BSA particularly important?
A: Critical for chemotherapy dosing, pediatric medicine, and when adjusting for patients with extreme body weights.

Q4: How accurate is this calculation?
A: The Haycock formula is accurate to within 1-2% for most individuals when proper measurements are taken.

Q5: Can I use pounds and inches?
A: This calculator requires metric units (kg and cm) for accuracy. Convert imperial units first (1 kg = 2.2 lbs, 1 inch = 2.54 cm).
