Neonatal and pediatric assessment adapts adult techniques to smaller, rapidly changing patients. Gestational age Age of the pregnancy in weeks Full entry → and maternal history set the risk context, while APGAR scoring (at 1 and 5 minutes) summarizes a newborn's transition to extrauterine life. The Silverman-Anderson score Five-sign score of respiratory distress (0–10) Full entry → grades respiratory distress, chest Transillumination Shining light through the chest wall Full entry → helps detect a pneumothorax, and capillary blood gases offer a less invasive alternative to arterial sampling. Because normal vital signs vary sharply with age, pediatric values are always interpreted against age-specific reference ranges.
Why this matters
Newborns and children decompensate quickly, and their "normal" spans a wide age-dependent range. The respiratory therapist's professional role is to obtain accurate, age-appropriate measurements, recognize subtle signs of distress (Grunting Expiratory sound from partial glottic closure Full entry →, flaring, Retractions Inward pulling of chest wall on inhale Full entry →) early, and escalate before a baby tires. Misreading a pediatric heart rate or respiratory rate against adult norms can delay recognition of deterioration. Scores like APGAR and Silverman-Anderson are most useful as trends rather than single snapshots. All normal ranges, scoring methods, oxygen-saturation targets, and assessment protocols must be verified against the current NBRC detailed content outline, candidate handbook, AARC clinical practice guidelines, Neonatal Resuscitation Program (NRP) guidance, facility protocols, state licensure requirements, provider orders, and manufacturer instructions for use.
The college version
1. Gestational Age and Maternal History
Gestational age is how far along the pregnancy is, counted in weeks. It is established from maternal history (last menstrual period and ultrasound dating) and confirmed after birth by physical scoring tools such as the Ballard score. Categories matter because lung maturity tracks gestational age:
- Preterm Born before 37 weeks Full entry → (before 37 weeks) — higher risk of respiratory distress syndrome from surfactant deficiency.
- Term (37 to 42 weeks).
- Post-term (after 42 weeks).
Babies are also classified as small, appropriate, or large for gestational age (SGA/AGA/LGA).
Maternal history flags respiratory and other risk: maternal diabetes, hypertension or preeclampsia, prolonged rupture of membranes, infection (including group B streptococcus), substance use, certain medications, the mode of delivery, and meconium-stained fluid. Each of these helps the team anticipate what a newborn might face.
2. APGAR Scoring (1 and 5 Minutes)
The APGAR score Five-part score (0–10) at 1 and 5 minutes Full entry → evaluates a newborn at 1 minute (immediate transition) and again at 5 minutes (response to any support). Each of five components is scored 0, 1, or 2, for a total of 0–10:
- A — Appearance (color): 0 blue/pale, 1 body pink with blue extremities, 2 completely pink.
- P — Pulse (heart rate): 0 absent, 1 below 100/min, 2 at or above 100/min.
- G — Grimace (reflex irritability): 0 no response, 1 grimace, 2 cry or vigorous response.
- A — Activity (muscle tone): 0 limp, 1 some flexion, 2 active movement.
- R — Respiration: 0 absent, 1 slow/irregular, 2 strong cry.
A score of 7–10 is generally reassuring, 4–6 indicates moderate depression, and 0–3 indicates severe depression requiring urgent escalation. Scores that remain low at 5 minutes (and later rechecks) are more concerning than a low 1-minute score that recovers quickly.
3. Respiratory Distress, Transillumination, and Capillary Gases
The Silverman-Anderson score grades the severity of neonatal respiratory distress using five signs, each scored 0–2 (total 0–10, higher = more distress): upper-chest retractions, lower-chest retractions, xiphoid retractions, Nasal flaring Widening of the nostrils with breathing Full entry →, and expiratory grunting. It is used to monitor the course of respiratory distress and the response to interventions.
Transillumination of the chest uses a bright light placed against the chest wall. Because air transmits light, a pneumothorax (air in the pleural space) makes one side "light up" more than the other. It is a rapid bedside check when a pneumothorax is suspected in a newborn.
Capillary blood gases are drawn from a warmed heel (or finger) as an alternative when arterial access is difficult or undesirable in infants. Warming "arterializes" the capillary blood. pH, PCO2, and bicarbonate correlate reasonably well with arterial values, but the PO2 from a capillary sample is unreliable and can underestimate arterial oxygenation. Capillary gases are therefore used mainly to follow acid-base and ventilation status, not oxygenation.
4. Pediatric Vital Signs and Normal Values
Normal values change with age, and they trend in opposite directions for different parameters:
- Heart rate is highest in newborns (about 120–160 beats/min) and declines through infancy, childhood, and adolescence toward adult values.
- Respiratory rate is also highest in newborns (about 30–60 breaths/min) and falls with age.
- Blood pressure is lowest in newborns and rises steadily with age.
- Temperature stays near 36.5–37.5 °C (97.7–99.5 °F), but newborns are prone to heat loss.
- Oxygen saturation (SpO2) targets are age- and context-dependent and must follow provider orders and facility policy.
Because a value that is normal for a newborn may be abnormal for a teenager, pediatric vital signs are always read against age-specific reference charts.
How it works
- At delivery, the newborn is assessed and APGAR scored at 1 minute and again at 5 minutes (with later rechecks if the score is low).
- For a baby in respiratory distress, the Silverman-Anderson score is assigned by observing chest retractions, nasal flaring, and grunting.
- If a pneumothorax is suspected, a bright light is placed against the chest; increased light transmission on one side suggests air in the pleural space.
- When gas values are needed, the heel is warmed to increase blood flow and a capillary sample is collected and analyzed.
- Vital signs are measured and plotted against age-specific reference ranges, with repeated measurements used to follow trends.
Common confusions
| Do not confuse | With | Difference |
|---|---|---|
| APGAR score (transition at birth) | Silverman-Anderson score (ongoing distress) | APGAR scores the newborn's first transition; Silverman-Anderson grades work of breathing |
| Gestational age (weeks of pregnancy) | Chronologic/postnatal age (age since birth) | Gestational age predicts maturity; postnatal age is time since delivery |
| Capillary blood gas (heel/finger) | Arterial blood gas (artery) | Capillary samples are less invasive but give unreliable PO2 |
| Transillumination (light through chest) | Chest radiograph | Transillumination is a rapid bedside screen; radiography confirms findings |
| Preterm (before 37 weeks) | Low birth weight | Preterm is a timing category; birth weight is a size category (and they can overlap) |

Quick review
Topic Recap
Neonatal and pediatric assessment begins with risk context — gestational age and maternal history — then moves to scoring. APGAR (Appearance, Pulse, Grimace, Activity, Respiration) at 1 and 5 minutes summarizes the newborn's transition, while the Silverman-Anderson score grades ongoing respiratory distress through retractions, nasal flaring, and grunting. Transillumination offers a rapid bedside check for pneumothorax, and capillary blood gases provide a less invasive acid-base/PCO2 trend (but not reliable oxygenation). Pediatric vital signs are always read against age-specific ranges: heart rate and respiratory rate fall with age while blood pressure rises. Recognize the signs, watch the trend, and escalate promptly — never manage a deteriorating infant alone.
Knowledge Check
- At what two times is the APGAR score assigned?
- Which APGAR component is scored 2 when the heart rate is above 100 beats per minute?
- What does a rising Silverman-Anderson score indicate?
- Which gas value is unreliable on a Capillary blood gas Gas sample from a warmed heel/finger Full entry →?
- How do pediatric heart rate and respiratory rate change as a child grows?
Answers and Rationales
- 1 minute and 5 minutes (with additional rechecks if the score stays low). The 1-minute score reflects the initial transition and the 5-minute score reflects the response to support.
- Pulse. A heart rate at or above 100 beats per minute earns the maximum 2 points for that component.
- Worsening respiratory distress. Higher totals mean more retractions, flaring, and grunting — more work of breathing.
- PO2. Capillary samples "arterialized" from a warmed heel correlate poorly with arterial oxygen tension; pH and PCO2 are more reliable.
- Both decrease with age. Newborns have the highest heart rate and respiratory rate; these fall toward adult values through childhood while blood pressure rises.
Eli explains
The same idea, in plain words
Explain it like I’m 10
A newborn's lungs are switching from "not used yet" to "working full time" in the first minutes of life. Imagine a brand-new engine starting for the very first time — you check that it is running, how smoothly, and whether it is struggling. The APGAR score is that quick first check: five simple things (color, heart rate, reflexes, muscle tone, breathing) scored at one minute and again at five minutes. A baby who is a little slow to start often simply needs warmth and stimulation; a baby who is not improving needs urgent help.
For comparison, think of the difference between scoring a newborn's transition (APGAR) versus scoring how hard a baby is working to breathe once breathing has begun (Silverman-Anderson). One asks "is everything coming online?" and the other asks "how much effort is this breathing taking?"
Where this stops being exact: these scores are screening and monitoring tools, not diagnoses. A low APGAR or a high Silverman-Anderson score tells the team something is wrong and how severe it looks, but figuring out the exact cause and directing treatment is the physician's responsibility. The respiratory therapist recognizes the score, monitors its trend, and escalates concerning findings.
Simple Example
A newborn at one minute has a blue body, a heart rate of 90, some limb movement, a grimace when stimulated, and slow, irregular breaths. That is a low APGAR score. At five minutes the baby is pink, crying, moving all limbs, with a heart rate over 100 — a much higher score, showing the baby is transitioning well.
Worked example
Approaching a newborn's respiratory status follows a "why" at each step:
- Start with risk context. Gestational age, maternal history, and delivery details tell you what problems to anticipate before the first assessment.
- Score the transition (APGAR at 1 and 5 minutes). The 1-minute score reflects the initial transition; the 5-minute score reflects the response to support and carries more prognostic weight.
- Grade the work of breathing (Silverman-Anderson). Retractions, nasal flaring, and grunting each signal increasing effort and should prompt closer monitoring and escalation as the score rises.
- Look for an acute, treatable cause. If distress appears or worsens, transillumination of the chest is a rapid bedside check for pneumothorax.
- Check gas exchange when needed. A capillary blood gas can follow pH and PCO2 trends with less risk than repeated arterial punctures, but is not a substitute for measuring oxygenation.
- Compare vital signs to age-specific norms. Heart rate and respiratory rate are interpreted only against the correct age band; trends matter more than any single value.
- Escalate, never manage alone. Any worsening score, sudden change, or unstable vital sign requires immediate escalation to qualified clinicians or activation of local emergency response.
Key takeaways
- High yield: APGAR is scored at 1 and 5 minutes; the 5-minute score and its trend matter more than the 1-minute score alone.
- High yield: APGAR components are Appearance, Pulse, Grimace, Activity, Respiration — each scored 0–2.
- High yield: Preterm babies (before 37 weeks) are at high risk of respiratory distress syndrome from surfactant deficiency.
- High yield: The Silverman-Anderson score includes retractions, nasal flaring, and expiratory grunting; a rising score means worsening distress.
- High yield: Transillumination lights up the side of a pneumothorax because air transmits light.
- Capillary blood gas PO2 is unreliable; use capillary samples for pH/PCO2/acid-base trends, not oxygenation.
- Newborn heart rate (≈120–160) and respiratory rate (≈30–60) are much higher than adult values and fall with age, while blood pressure rises with age.
- A score of 0–3 APGAR at any time, or a persistently low score, requires immediate escalation and emergency response.
