Pediatric Vital Signs

Introduction

Blood pressure, pulse rate and respiratory rate are the routine vital signs measured in medicine. These vital signs remain relatively constant throughout our adult life. However, as infants and children grow and age, the normal range changes. Two tables of normal vital signs for the pediatric population are presented below.

Age (yr)	Respiratory Rate (breaths/min)	Heart Rate (beats/min)
<1	30-60	100-160
1-2	24-40	90-150
2-5	22-34	80-140
6-12	18-30	70-120
>12	12-16	60-100
Lower limits of systolic pressure†
0-28 days: 60 mmHg 1-12 months: 70 mm Hg 1-10 years: 70 mm Hg + (2¥ age in years)
