1. What is a Pediatric Blood Pressure Calculator?

Definition: This calculator determines a child's blood pressure percentile based on age, height, sex, and blood pressure measurements.

Purpose: It helps healthcare providers assess whether a child's blood pressure is normal for their age and size.

2. How Does the Calculator Work?

The calculator uses standardized pediatric blood pressure tables that account for:

\[ BP_{percentile} = f(age, height, sex, BP) \]

Where:

Explanation: The calculator compares the measured BP against normative data for children of the same age, height, and sex.

3. Importance of Pediatric BP Assessment

Details: Children's BP norms vary by growth and development. Percentiles help identify hypertension or hypotension early.

4. Using the Calculator

Tips: Enter the child's exact age, measured height, sex, and recent blood pressure measurements for accurate results.

A: Generally, <90th percentile is normal, 90-95th is elevated, and ≥95th indicates hypertension.

Q2: How often should children's BP be checked?
A: Annually for children ≥3 years, or more frequently if risk factors exist.

Q3: What if my child's BP is high?
A: Consult a pediatrician. Elevated readings should be confirmed on multiple occasions.
