Estimate paediatric blood pressure percentiles by age, sex and height.
Paediatric blood pressure thresholds depend on age, sex and height rather than being fixed, which is why a reading normal for one child can be elevated for another of the same age. This uses a simplified reference. A single elevated reading does not establish hypertension in children, which requires repeated measurements on separate occasions with correct cuff sizing.
Blood Pressure Percentile
Percentile derived from an age, sex and height adjusted reference distribution
This reproduces a published formula for educational and reference use only. It is not a diagnostic tool, does not account for individual clinical context, and must not be used to make or change treatment decisions. Clinical assessment by a qualified healthcare professional is always required. This uses a simplified reference and is not equivalent to official paediatric blood pressure tables. Cuff size and measurement technique substantially affect readings. Paediatric blood pressure must be assessed by a healthcare professional.
