Definition of Hypotension and By Systolic Blood Pressure For Age
Term neonate (0 to 28 days) : < 60 mm Hg
Infants (1 to 12 months) < 70
Children 1 to 10 years (5th percentile for BP) < 70 + ( 2 x age in years)
Children > 10 years (are like adults) <90
The following formula applies for infants (1 mo to 12 months) and children 1 to 10 years.
Minimum SBP = 70 mmHg + (2 x Age in years)
For infants, the age is considered to be 0 years.
Median Blood Pressure
Median SBP = 90 mmHg + (2 x Age in years)
Heart Rate
HR per minute
| Age | Awake Rate | Sleeping Rate |
| 0 to 3 months | 85 to 205 | 80 to 160 |
| 3 months to 2 years | 100 to 190 | 75 to 160 |
| 2 years to 10 years | 60 to 140 | 60 to 90 |
| > 10 years | 60 to 100 | 50 to 90 |
Respiratory Rate
RR in breaths/minute
| Age | Rate |
| Infant | 30 to 60 |
| Toddler | 24 to 40 |
| Preschooler | 22 to 34 |
| School Aged | 18 to 30 |
| Adolescent | 12 to 16 |
Temperature and oxygen saturations are the same for all ages, with little difference.
