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.

Blood pressure

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