Pediatric Vital Signs

Quick Overview

Blood pressure, body temperature, pulse rate, and respiratory rate are the routine vital signs measured in medicine. These vital signs remain relatively constant throughout our adult life.

As infants and children grow and age, their normal values for vital signs change. Body temperature does not change with age, and normal body temperature is considered 98.6 F (37 C).

Two tables of normal vital signs for the pediatric population are presented below. Heart rates may be slightly slower when asleep.

Table 1: Heart Rate at Various Ages

Age (year) Respiratory Rate (breaths/min)Heart Rate (beats/min)
<1 30-60100-160

Lower limits of systolic pressure†

  • 0-28 days: 60 mm Hg
  • 1-12 months: 70 mm Hg
  • 1-10 years: 70 mm Hg + (2 times age in years)
