Normal Values in Children
During evaluation, conduct the primary assessment, secondary assessment, and diagnostic tests. If at any time a condition is determined to be life-threatening, intervene immediately.
Primary Assessment
Assessment | Assessment Techniques | Abnormal Findings | Interventions |
A – Airway | Observe for movement of the chest or abdomen; Listen to the chest for breath sounds | Obstructed but maintainable | Keep airway open by head tilt/chin lift |
Obstructed and cannot be opened with simple interventions | Keep airway open using advanced interventions | ||
B – Breathing | Rate | <10 or >60 = Abnormal (apnea, bradypnea, tachypnea) | Immediate respiratory intervention required |
Effort | Nasal flaring, head bobbing, seesaw respirations, retractions | Immediate respiratory intervention required | |
Chest or abdominal expansion | Asymmetrical or no chest movement | Immediate respiratory intervention required | |

Table 3: Primary Assessment Model
Use the Primary Assessment to evaluate the child using vital signs and an ABCDE model:
A – Airway
Head tilt-chin lift and jaw thrust may be used to open the airway quickly and without the use of an advanced airway. The jaw thrust maneuver is preferred when a cervical spine injury is suspected or cannot be ruled out.
Advanced interventions for maintaining a patent airway may include:
- Laryngeal mask airway (LMA)
- Endotracheal (ET) intubation
- Continuous positive airway pressure (CPAP)
- Foreign body removal if one can be visualized
- Cricothyrotomy in which a surgical opening is made into the trachea.
B – Breathing
The child’s respiratory rate is an important assessment that should be made early in the primary assessment process. The clinician must be aware of normal respiratory ranges by age:
Age Category | Age Range | Normal Respiratory Rate |
Infant | 0-12 months | 30-60 per minute |
Toddler | 1-3 years | 24-40 per minute |
Preschooler | 4-5 years | 22-34 per minute |
School age | 6-12 years | 18-30 per minute |
Adolescent | 13-18 years | 12-16 per minute |
Table 4: Normal Respiratory Rates
A respiratory rate that is consistently below 10 or above 60 breaths per minute indicates a problem that needs immediate attention. Periodic breathing is not unusual in infants; therefore, you may have to spend more time observing the infant’s breathing to determine true bradypnea or tachypnea. Nasal flaring and retractions indicate increased work of breathing. Head bobbling or seesaw respirations are potential signs of impending deterioration. Likewise, slow and/or irregular breathing suggest imminent respiratory arrest.
C – Circulation
The child’s heart rate is another important assessment that should be made in the primary assessment. The normal heart rates by age are:
Age Category | Age Range | Normal Heart Rate |
Newborn | 0-3 months | 80-205 per minute |
Infant/young child | 4 months to 2 years | 75-190 per minute |
Child/school age | 2-10 years | 60-140 per minute |
Older child/ adolescent | Over 10 years | 50-100 per minute |
Table 5: Normal Heart Rates
The child’s blood pressure should be another part of the primary assessment. Normal blood pressures by age range are:
Age Category | Age Range | Systolic Blood Pressure | Diastolic Blood Pressure | Abnormally Low |
Systolic Pressure | 1 Day | 60-76 | 30-45 | <60 |
Neonate | 4 Days | 67-84 | 35-53 | <60 |
Infant | To 1 month | 73-94 | 36-56 | <70 |
Infant | 1-3 months | 78-103 | 44-65 | <70 |
Infant | 4-6 months | 82-105 | 46-68 | <70 |
Infant | 7-12 months | 67-104 | 20-60 | <70 + (age in years x 2) |
Preschool | 2-6 years | 70-106 | 25-65 | <70 + (age in years x 2) |
School Age | 7-14 years | 79-115 | 38-78 | <70 + (age in years x 2) |
Adolescent | 15-18 years | 93-131 | 45-85 | <90 |

D – Disability
One of the assessments of level of consciousness in a child is the Pediatric Glasgow Coma Scale (GCS).
Response | Score | Verbal Child | Pre-Verbal Child |
Eye opening |
4 3 2 1 |
Spontaneously
To verbal command To pain None |
Spontaneously
To speech To pain None |
Verbal response |
5 4 3 2 1 |
Oriented and talking
Confused but talking Inappropriate words Sounds only None |
Cooing and babbling
Crying and irritable Crying with pain only Moaning with pain only None |
Motor response |
6 5 4 3 2 1 |
Obeys commands
Localizes with pain Flexion and withdrawal Abnormal flexion Abnormal extension None |
Spontaneous movement
Withdraws when touched Withdraws with pain Abnormal flexion Abnormal extension None |
Total Possible Score |
3-15 |
Table 7: Pediatric Glasgow Coma Scale
When there is a suspected or known head injury, a GCS score of 13 to 15 is considered mild, 9 to 12 is moderate, and 3 to 8 is severe. In intubated or sedated children, motor response provides the most important information. The lower the motor response score, the more serious the deficit/injury.
E – Exposure
If the provider finds any abnormal symptoms in this category they should assess and treat the child for shock (see Unit Seven: Management of Pediatric Shock, particularly Interventions for Initial Management of Shock). During the primary assessment, if the child is stable and does not have a potentially life-threatening problem, continue with the secondary assessment.
