bmi-bsa-calculator

What This Skill Does

The bmi-bsa-calculator is a specialized clinical utility designed for health professionals and AI agents requiring precise anthropometric calculations. It bridges the gap between raw patient metrics (weight and height) and actionable clinical data. The skill computes Body Mass Index (BMI) using both standard and age-adjusted methods, while simultaneously providing Body Surface Area (BSA) estimates through multiple validated scientific formulas, including DuBois, Mosteller, and Haycock. Beyond mere arithmetic, the tool classifies weight based on WHO and CDC norms, making it an essential component for obesity screening, pediatric development tracking, and precise chemotherapy dose calculations where drug toxicity is highly correlated with surface area.

Installation

To integrate this skill into your OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/aipoch-ai/bmi-bsa-calculator Ensure you have the necessary permissions to install packages from the central repository before proceeding.

Use Cases

This skill is highly versatile in a clinical or research setting. Primary use cases include:

• Chemotherapy Dosing: Calculating BSA to determine appropriate mg/m² drug dosages for oncology patients.
• Obesity Management: Automating the documentation of BMI categories for routine wellness exams and monitoring weight trends over time.
• Pediatric Assessments: Providing age-appropriate anthropometric context for growing children.
• Clinical Research: Running batch calculations for clinical trial subjects to normalize physiological data across diverse patient cohorts.
• Medication Safety: Assisting in the verification of weight-based dosing for high-risk medications where under- or over-dosing carries significant safety implications.

Example Prompts

1. "Calculate the BMI for a patient who is 180cm and 85kg, and provide the WHO weight classification."
2. "Determine the BSA for a 75kg, 170cm patient using both the DuBois and Mosteller formulas for my chemotherapy dose calculation."
3. "Evaluate the anthropometrics for a 50-year-old male, 190cm, 100kg. Does he fall into the obese range, and what is his calculated BMI prime?"

Tips & Limitations

While the calculator provides high-precision mathematical results, remember that anthropometrics are just one part of a total clinical picture. Always use this tool as a decision-support aid rather than a diagnostic replacement. Avoid relying on BMI alone for athletic patients with high muscle mass or pregnant individuals, as it may misrepresent their health status. Always perform a physical examination and metabolic review alongside these calculations to ensure patient safety and care quality.
