Pediatric blood pressures are "normed" by age, gender, and height percentiles. Current tables list 90% and 95% cutoff values for systolic and diastolic BP. It would be very useful to be able to enter gender, birthdate, height (birthdate + height + gender needed to calculate height percentile) and blood pressure, and get the percentiles for systolic and diastolic.
