Normal Vital Signs

In most medical settings, the four standard primary vital signs are as follows: [1]

  • Heart rate (pulse)
  • Respiratory rate
  • Blood pressure
  • Body temperature

Normal values for each of these vital signs vary by age and, in some cases, by sex.

Heart rate

Approximate Age Range Heart Rate
Newborn 100-160
0-5 months 90-150
6-12 months 80-140
1-3 years 80-130
3-5 years 80-120
6-10 years 70-110
11-14 years 60-105
15-20 years 60-100
Adults 50-80

Respiratory rate

Approximate Age Range Respiratory Rate
Newborn 30-50
0-5 months 25-40
6-12 months 20-30
1-3 years 20-30
3-5 years 20-30
6-10 years 15-30
11-14 years 12-20
15-20 years 12-30
Adults 16-20

Blood pressure

The normal blood pressure in adults is 120 (systolic)/80 (diastolic). Normal blood pressure in children and adolescents varies by age.

Approximate Age Range Systolic Range Diastolic Range
1-12 months 75-100 50-70
1-4 years 80-110 50-80
3-5 years 80-110 50-80
6-13 years 85-120 55-80
13-18 years 95-140 60-90

Temperature

The average normal core temperature is generally considered to be between 98.0°F (36.6°C) and 98.6°F (37°C) when measured orally and about 1°F higher when measured rectally. [2]
