Interpreting blood pressure measurements for children is complicated by the need to account for a constantly changing body size. It is time-consuming to calculate and/or perform data entry during a patient visit, yet assessment of blood pressure percentiles is medically recommended from the age of 3 onward because 75% of cases of pediatric hypertension and 90% of cases of pre-hypertension in children from 3 to 18 years of age are left undetected.
The BP Centiles app reads a child’s relevant vitals and calculates systolic and diastolic blood pressure percentiles normalized by age, sex, and height. The app also includes a pop-up calculator and a graphical history of the child"s blood pressure percentile, enabling full screening at each visit.
Color coding reveals at a glance whether individual readings are normal (green), prehypertensive (yellow), hypertensive (red) or hypotensive (blue). Users can zoom in on a group of readings for more information and apply relevant filters to help them interpret the measurements—such as looking only at BPs measured in the legs, sitting down or by machine.
