Interpreting blood pressure readings for children is somewhat complicated compared to adults.
These adjusted readings are then compared to complicated tables that list percentile ranges.
The compiled blood pressure percentile charts are available for download online.

To use the standard charts, first, ensure that you choose the proper male or female chart.
Scan the left-most vertical column to find the row that matches your childs age.
Notice that each age has individual rows for the 90th and 95th percentileblood pressure.
The vertical columns each represent a height percentile.
This process sounds more complicated than it actually is.
Lets try an example.
Say that you have a 4-year-old boy who is 103cm tall (40.5 inches, or about 3.5ft).
You first look at the CDC height by age chart to find your childs height percentile.
While the process isnt very difficult, it can be confusing and time-consuming.
