1. What is a Pediatric Blood Pressure Calculator for Girls?

Definition: This calculator determines blood pressure percentiles for girls aged 1-17 years based on age, height, and measured BP values.

Purpose: It helps healthcare providers assess whether a girl's blood pressure is normal for her age and height according to pediatric guidelines.

2. How Does the Calculator Work?

The calculator uses sex-specific pediatric blood pressure tables from the American Academy of Pediatrics:

Key Factors:

• Age: From 1 year to 17 years (pediatric range)
• Height: Measured in centimeters (important for accurate percentile calculation)
• Blood Pressure: Both systolic and diastolic measurements in mmHg

Output: Percentile ranking compared to healthy girls of same age and height.

3. Importance of BP Percentile Calculation

Clinical Significance:

• Normal BP: <90th percentile
• Elevated BP: 90th-95th percentile
• Hypertension: ≥95th percentile

4. Using the Calculator

Instructions:

1. Enter age in years (can include decimals for months)
2. Enter current height in centimeters
3. Enter measured systolic and diastolic blood pressures
4. Click "Calculate" to get percentile results

5. Frequently Asked Questions (FAQ)

Q1: Why are separate calculators needed for boys and girls?
A: Boys and girls have different normal BP ranges during growth and development.

Q2: What's the youngest age this calculator works for?
A: This calculator is valid for girls aged 1 year through 17 years.

Q3: How often should children's BP be checked?
A: Annual screening is recommended starting at age 3, or earlier for high-risk children.

Q4: What if my patient is exactly at a percentile cutoff?
A: Borderline results should be confirmed with repeated measurements on separate occasions.

Q5: Where can I find the reference tables?
A: The reference tables are published in the AAP Clinical Practice Guideline for Screening and Management of High BP in Children and Adolescents.
