Summary

Enter a child's age, sex, height percentile, systolic and diastolic BP to get their blood pressure percentile and AAP 2017 classification.

How it works

  1. Select the child's sex (male or female).
  2. Enter the child's age in whole years (1 through 17).
  3. Choose the child's height percentile (5th, 10th, 25th, 50th, 75th, 90th, or 95th).
  4. Enter the measured systolic and diastolic blood pressure in mmHg.
  5. The calculator looks up the AAP 2017 normative table row for that age, sex, and height percentile to find the 50th, 90th, 95th, and 99th percentile thresholds.
  6. It interpolates between height percentile columns when needed and classifies the reading per AAP 2017 cut-points.

Use cases

  • Screen children for hypertension at well-child visits.
  • Confirm whether a single elevated office reading warrants follow-up.
  • Educate parents on where their child's blood pressure stands relative to peers.
  • Support clinical decision-making when referring to a pediatric cardiologist or nephrologist.
  • Track blood pressure trends across annual visits.
  • Quickly apply AAP 2017 definitions without manual table lookups.
