1. What is a Blood Pressure Calculator by Age?

Definition: This calculator determines blood pressure categories based on age-specific percentiles and ranges.

Purpose: It helps assess whether blood pressure readings are normal, elevated, or indicate hypertension for different age groups.

2. How Does the Calculator Work?

The calculator uses different criteria for:

• Children (1-17 years): Based on age-specific percentiles
• Adults (18+ years): Based on standard hypertension guidelines

3. Importance of Age-Specific BP Assessment

Details: Normal blood pressure ranges vary significantly by age, especially in children and adolescents.

4. Using the Calculator

Tips: Enter the patient's age in years, systolic BP (mmHg), and diastolic BP (mmHg). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why different criteria for children vs adults?
A: Children's BP norms increase with age and growth, while adult standards are fixed.

Q2: What's considered normal BP for a 10-year-old?
A: Typically around 102/61 mmHg, but varies by height percentile.

Q3: When is BP considered high in adults?
A: 130-139/80-89 mmHg is Stage 1, ≥140/90 mmHg is Stage 2 hypertension.

Q4: How accurate is this calculator?
A: It provides general guidance but consult a doctor for medical diagnosis.

Q5: Does this account for height in children?
A: This simplified version doesn't; for precise percentiles, use detailed pediatric charts.
