General-reference style output summarizing normal pediatric vital sign ranges by age group.
Query: What are the pediatric vital sign normal ranges by age?
Summary
Pediatric vital signs vary substantially by age. Generally, younger children have higher heart rates and respiratory rates, with systolic blood pressures increasing with age. Refer to the age-stratified table below for normal ranges in key parameters such as pulse, respiratory rate, and systolic blood pressure .
