LOW RISK Mosteller RD. Simplified calculation of body-surface area. N Engl J Med 1987;317:1098; ASCO Guidelines for Appropriate Chemotherapy Dosing in Obese Patients (1987)

Mosteller Body Surface Area (BSA)

Applicable Population: Pediatric and adult patients for medication dosing indexation

Calculated Score: 1.95 m²

Clinical Interpretation

Calculated Body Surface Area: 1.95 m²

Guideline-Directed Recommendation

Use 1.95 m² for chemotherapy and cardiac index calculations. Per ASCO guidelines, use actual body weight for BSA calculation without empirical dose reduction in obese adult patients.

Clinical Alerts & Safety Warnings

Always double-check chemotherapy dosing protocols with a clinical oncology pharmacist before infusion.

Deterministic Execution Trace

Zero-Token Arithmetic

Mathematical Formula \text{BSA} = \sqrt{\frac{\text{Height (cm)} \times \text{Weight (kg)}}{3600}} \quad [\text{m}^2]

Step-by-Step Formula Progression:

1 Formula: BSA = sqrt( (Height_cm * Weight_kg) / 3600 )

2 Height: 175 cm, Weight: 78 kg

3 Product: 13650 / 3600 = 3.7917
