From: | To: |
Definition: This calculator determines a child's blood pressure percentile based on age, height, sex, and measured blood pressure.
Purpose: It helps healthcare providers and parents assess whether a child's blood pressure is normal for their age and size.
The calculator uses pediatric guidelines to compare the child's blood pressure against normative data:
Where:
Explanation: The calculation accounts for normal variations in blood pressure as children grow.
Details: Unlike adults, children's blood pressure norms vary by age, sex, and height. Percentiles help identify potential hypertension.
Tips: Enter the child's exact age (can include decimals for months), measured height, sex, and current blood pressure reading.
Q1: What is a normal blood pressure percentile for children?
A: Generally, below 90th percentile is normal, 90th-95th is elevated, and above 95th may indicate hypertension.
Q2: How often should children's blood pressure be checked?
A: Annually for children over 3 years, or more frequently if risk factors exist.
Q3: Why does height matter in blood pressure assessment?
A: Taller children typically have slightly higher normal blood pressure ranges than shorter children of the same age.
Q4: What if my child's percentile seems high?
A: Consult a pediatrician. Multiple elevated readings are needed for diagnosis.
Q5: How accurate is this calculator?
A: This provides an estimate based on normative data. Clinical assessment is required for diagnosis.
