Paediatric vital signs vary by the child’s age. Generally, the normal heart rate and respiratory declines as a child grows, and the normal blood pressure increases.
Unlike adult vital signs, the exact reference ranges for paediatrics are not universally agreed upon and there is some variation between sources. The table below is an approximation based on several sources, most closely approximated to those recommended by The Royal Children’s Hospital, Melbourne.
Heart rate (bpm)
Respiratory rate (/min)
Systolic blood pressure (mmHg)
< 3 months
Over 12 years
*Note – some sources report HR up to 120 as within the normal range for individuals under 17
