Neonatal and Pediatric Assessment in Respiratory Care (2026)

Neonatal and pediatric patient assessment is the process of evaluating newborns, infants, and children to identify signs of respiratory distress, determine illness severity, guide treatment, and monitor response to therapy.

Because infants and children are not simply small adults, their assessment requires an understanding of age-specific anatomy, physiology, development, and disease patterns.

Respiratory therapists must know how to evaluate maternal history, fetal status, newborn transition, vital signs, work of breathing, oxygenation, ventilation, and physical examination findings to recognize problems early and respond appropriately.

Why Neonatal and Pediatric Assessment Is Different

Assessing a neonate or child is different from assessing an adult because the respiratory, cardiovascular, neurologic, and immune systems are still developing. A newborn has limited cardiopulmonary reserve, smaller airways, a more compliant chest wall, and a higher metabolic rate. This means that respiratory distress can progress quickly if it is not recognized and treated.

Infants and young children also depend heavily on their respiratory rate and effort to maintain adequate ventilation. A small increase in airway resistance can create a large increase in work of breathing. Conditions such as bronchiolitis, croup, asthma, pneumonia, congenital heart disease, respiratory distress syndrome, and airway obstruction can all produce serious symptoms in a short period of time.

The clinician must also adapt the assessment to the child’s age and developmental level. A newborn cannot describe symptoms. An infant may show illness through feeding difficulty, lethargy, irritability, apnea, or color change. An older child may be able to report shortness of breath, chest tightness, pain, cough, or fatigue. For this reason, neonatal and pediatric assessment combines observation, history, physical examination, diagnostic data, and trend monitoring.

Assessment Before Birth

Neonatal assessment begins before delivery with a review of the maternal, fetal, and perinatal history. Maternal health can strongly affect fetal oxygenation, fetal growth, lung development, and the newborn’s ability to transition after birth.

Important maternal risk factors include diabetes mellitus, hypertension, preeclampsia, placenta previa, abruptio placentae, smoking, alcohol use, drug use, anemia, chronic lung disease, heart disease, renal disease, poor nutrition, lack of prenatal care, and extremes of maternal age. Mothers younger than 16 years or older than 40 years are often considered higher risk, especially when additional complications are present.

Labor and delivery factors must also be reviewed. These include premature rupture of membranes, prolonged rupture of membranes, premature labor, postmature labor, rapid labor, prolonged labor, cesarean section, breech presentation, prolapsed umbilical cord, maternal anesthesia, and analgesic use. Each factor can influence the newborn’s risk of respiratory depression, infection, birth trauma, or the need for resuscitation.

Fetal factors are equally important. Multiple births, meconium-stained amniotic fluid, abnormal fetal heart rate, fetal acidosis, prematurity, postmaturity, abnormal size for gestational age, Rh sensitization, congenital malformations, immature lung maturity studies, and birth trauma may all indicate that the newborn is at higher risk after delivery.

Note: A key point in neonatal care is that not every high-risk infant is identified before birth. Some infants who need support at delivery have no obvious warning signs in the maternal record. For this reason, the healthcare team must always be prepared to assess and support the newborn immediately after birth.

Fetal Assessment

Fetal assessment provides information about how well the fetus is tolerating pregnancy and labor. Common methods include ultrasonography, amniocentesis, fetal heart rate monitoring, and, in some situations, fetal blood gas analysis.

Ultrasonography can help evaluate fetal position, fetal growth, placental location, amniotic fluid volume, and possible anatomic abnormalities. Amniocentesis may be used to inspect amniotic fluid for meconium or blood, evaluate fetal cells, or assess fetal lung maturity. Markers such as the lecithin-to-sphingomyelin ratio and the presence of phosphatidylglycerol can help estimate the likelihood that the infant’s lungs are mature enough for effective gas exchange after birth.

Fetal heart rate monitoring is especially important during labor. A normal fetal heart rate is generally between 120 and 160 beats/min. Fetal tachycardia may be associated with fetal hypoxemia, maternal fever, infection, prematurity, medication effects, or other stressors. Fetal bradycardia and reduced beat-to-beat variability may indicate fetal distress or asphyxia.

Decelerations are commonly described as early, late, or variable. Early decelerations usually occur with contractions and are often related to fetal head compression. These are generally less concerning if the fetal heart rate returns to normal after the contraction ends. Late decelerations are more concerning because they may indicate uteroplacental insufficiency, meaning impaired oxygen and blood flow between the mother, placenta, and fetus. Variable decelerations are often associated with umbilical cord compression and can reduce blood flow to the fetus.

Note: When concerning fetal heart rate patterns occur, the healthcare team may provide maternal oxygen, reposition the mother, monitor maternal blood pressure and heart rate, and prepare for urgent delivery if fetal asphyxia is suspected.

Immediate Newborn Stabilization

After birth, the first priority is to help the newborn transition from fetal to extrauterine life. Initial stabilization includes drying and warming the infant, maintaining an open airway, stimulating breathing, and evaluating the newborn’s response.

Preventing heat loss is extremely important. Cold stress increases oxygen consumption and can worsen respiratory distress. The infant should be dried quickly, wet linens should be removed, and warm blankets or radiant heat should be used. A cold newborn may become hypoxemic, acidotic, or unable to maintain adequate respiratory effort.

Positioning is also essential. The newborn’s head and neck should be placed in a neutral or slightly flexed position to keep the airway open. Hyperextension or excessive flexion can obstruct airflow. In some cases, a small roll under the shoulders can help align the airway.

If the infant’s breathing is ineffective, airway obstruction should be considered. The clinician may reposition the head and clear the airway as needed. Suctioning can be performed with a bulb syringe or suction catheter, typically clearing the mouth before the nose. However, suctioning should be performed carefully. Excessive suctioning can cause trauma, bradycardia, atelectasis, or interfere with the newborn’s breathing effort.

Note: Infants born through meconium-stained fluid require careful evaluation because meconium may contribute to airway obstruction, inflammation, and respiratory distress. The infant’s vigor, breathing effort, tone, and heart rate help guide the need for further intervention.

Apgar Score

The Apgar score is a structured method used to evaluate the newborn at 1 and 5 minutes after birth. It assesses five areas: heart rate, respiratory effort, muscle tone, reflex irritability, and color. Each category is scored as 0, 1, or 2, with a total possible score of 10.

A score of 7 to 10 is generally considered good, 4 to 6 is considered fair, and 0 to 3 is considered poor. The 1-minute score provides information about how well the infant tolerated birth. The 5-minute score provides information about how well the infant is adapting to life outside the uterus.

If the 5-minute Apgar score is less than 7, additional scores are commonly obtained every 5 minutes up to 20 minutes after delivery or until the infant improves. Heart rate is one of the most important parts of the Apgar score because it reflects the infant’s response to resuscitation and overall cardiopulmonary status. Color is considered one of the least reliable components because newborn skin color can be difficult to interpret immediately after birth.

The Apgar score is useful, but it should not replace clinical judgment. A newborn with poor respiratory effort, bradycardia, cyanosis, weak tone, or poor responsiveness needs immediate assessment and intervention regardless of the score.

Gestational Age and Growth Assessment

After initial stabilization, clinicians assess gestational age and growth. Gestational age is especially important because premature infants are at increased risk for respiratory distress syndrome, apnea, infection, poor temperature control, feeding problems, and neurologic complications.

Gestational age may be estimated using the mother’s last menstrual period, prenatal ultrasound findings, and postnatal physical and neurologic signs. The Ballard score and the Dubowitz score are commonly used methods for estimating maturity after birth. These tools assess physical and neurologic findings such as posture, skin texture, lanugo, plantar creases, breast tissue, ear cartilage, genital development, wrist flexibility, arm recoil, popliteal angle, scarf sign, and heel-to-ear maneuver.

A score consistent with 38 to 42 weeks suggests a term infant. A lower score suggests prematurity, while a higher score may suggest postmaturity. These estimates are not perfect, but they help guide clinical expectations and treatment decisions.

Once gestational age is determined, the infant’s birth weight, length, and head circumference are plotted on an appropriate growth chart. Infants are classified as small for gestational age, appropriate for gestational age, or large for gestational age. This classification matters because abnormal growth patterns may reflect intrauterine growth restriction, maternal diabetes, genetic conditions, placental problems, or other disease processes.

Neonatal Vital Signs

Vital signs are a major part of neonatal assessment. Normal values vary by gestational age, birth weight, illness severity, and clinical condition.

A normal newborn respiratory rate is commonly about 30 to 60 breaths/min, although premature infants may breathe faster. Tachypnea, usually defined as a respiratory rate greater than 60 breaths/min, can be associated with hypoxemia, acidosis, pain, anxiety, retained fetal lung fluid, pneumonia, sepsis, or respiratory distress syndrome.

A slower respiratory rate must be interpreted in context. For example, a respiratory rate of 36 breaths/min may be acceptable for a stable term newborn but concerning in a preterm infant who had previously been breathing 70 times per minute. Causes of slow breathing include hypothermia, medication effects, neurologic impairment, and fatigue.

A normal newborn heart rate is often about 100 to 160 beats/min, although some references describe a broader range depending on age and condition. The heart rate can be assessed by auscultating the apical pulse or palpating pulses such as the brachial or femoral pulse. Bradycardia, tachycardia, weak pulses, poor perfusion, poor tone, and poor responsiveness may indicate significant cardiopulmonary compromise.

Blood pressure varies by birth weight, gestational age, and postnatal age. Lower birth weight infants generally have lower blood pressure. Capillary refill, pulse quality, skin temperature, urine output, and overall perfusion should be assessed along with the blood pressure number.

Temperature assessment is also important. Newborns are vulnerable to heat loss because they have a large surface area compared with body mass and limited ability to regulate temperature. Hypothermia can worsen oxygen consumption, hypoglycemia, acidosis, and respiratory distress.

Neonatal Respiratory Assessment

Respiratory assessment is one of the most important parts of neonatal care. The clinician should observe the infant’s respiratory rate, rhythm, chest movement, work of breathing, airway patency, breath sounds, oxygen saturation, color, and response to interventions.

Common signs of neonatal respiratory distress include:

• Tachypnea
• Nasal flaring
• Grunting
• Retractions
• Head bobbing
• Apnea
• Cyanosis
• Poor chest movement
• Diminished breath sounds
• Abnormal breathing pattern

Grunting is an important sign because it may represent the infant’s attempt to maintain functional residual capacity. By partially closing the glottis during exhalation, the infant may be trying to keep the alveoli open. Nasal flaring suggests increased work of breathing. Retractions indicate that the infant is using extra effort to move air through small or obstructed airways.

Retractions may be intercostal, subcostal, suprasternal, substernal, or xiphoid. Severe retractions, see-saw breathing, poor chest expansion, or respiratory fatigue are concerning signs that may indicate impending respiratory failure.

Apnea must be assessed carefully. Periodic breathing can occur in premature infants and may include brief pauses in breathing. However, apnea associated with bradycardia, cyanosis, oxygen desaturation, limpness, or prolonged pauses is abnormal and requires prompt evaluation.

Note: Sudden changes in respiratory status should raise concern for serious problems such as pneumothorax, airway obstruction, equipment malfunction, pulmonary hemorrhage, sepsis, or worsening lung disease.

Silverman-Anderson Score

The Silverman-Anderson score is used to grade respiratory distress in newborns. It evaluates five signs: upper chest movement, lower chest movement, xiphoid retractions, nasal dilation, and expiratory grunting. Each sign is scored from 0 to 2.

A score of 0 indicates no signs of distress. A higher score suggests worsening respiratory distress. An infant with severe distress may have see-saw breathing, marked retractions, nasal flaring, and audible expiratory grunting.

Note: This scoring system can help clinicians describe the severity of respiratory distress, track changes over time, and communicate findings clearly to the healthcare team.

Transillumination for Pneumothorax

Transillumination may be used in neonates to help identify pneumothorax. Because the neonatal chest wall is thin, a bright light placed against the chest in a darkened room can help detect free air around a collapsed lung. If a pneumothorax is present, the affected side may show a brighter halo effect.

Transillumination is not a replacement for full clinical assessment or imaging when needed, but it can be useful as a rapid bedside tool in some neonatal situations. Pneumothorax should be suspected when there is sudden respiratory distress, asymmetric chest movement, decreased breath sounds on one side, worsening oxygenation, or acute deterioration during positive pressure ventilation.

Cardiovascular Assessment

The neonatal and pediatric cardiovascular assessment is closely connected to the respiratory assessment because heart and lung problems often overlap. Poor oxygenation may be caused by lung disease, congenital heart disease, shock, sepsis, or persistent pulmonary hypertension.

The clinician should assess heart rate, rhythm, pulses, perfusion, capillary refill, skin temperature, color, blood pressure, heart sounds, and the presence of murmurs. Cyanosis that does not improve as expected with oxygen therapy may suggest a cardiac cause. Weak pulses, prolonged capillary refill, cool extremities, mottling, or hypotension may suggest poor perfusion or shock.

In neonates, congenital heart disease may present with cyanosis, respiratory distress, poor feeding, lethargy, tachypnea, hepatomegaly, abnormal pulses, or a murmur. Some infants with serious congenital heart disease may appear stable at first and then deteriorate as fetal circulation changes after birth.

General Physical Examination of the Neonate

The physical examination includes more than the lungs. The clinician should observe the infant’s general appearance, posture, activity, tone, cry, color, and interaction with the environment.

A normal term newborn often rests with flexed extremities. Poor tone, weak movement, lethargy, irritability, or abnormal posture may suggest prematurity, neurologic depression, infection, trauma, metabolic problems, or medication effects.

The head and neck should be assessed for fontanel tension, facial features, airway anatomy, swelling, bruising, and congenital abnormalities. Abnormal jaw size, facial structure, or airway anatomy can increase the risk of airway obstruction.

The abdomen should be assessed for distention, masses, organ enlargement, bowel sounds, and congenital abnormalities. Conditions such as gastroschisis or omphalocele may affect respiratory support and overall management. Abdominal distention can impair ventilation by limiting diaphragmatic movement.

The musculoskeletal system should be evaluated for deformities, movement, symmetry, and possible birth injuries. Difficult deliveries may lead to brachial plexus injury, clavicle fracture, or other trauma.

Neurologic assessment includes evaluating responsiveness, tone, movement, and reflexes. Common newborn reflexes include the grasp reflex, plantar grasp reflex, Moro reflex, response to bright light, response to sound, and stepping reflex. Abnormal or absent reflexes may suggest neurologic immaturity, injury, illness, or medication effects.

Pediatric History

Assessment of older infants and children begins with a careful history. Even with modern diagnostic testing, a good history remains one of the most valuable tools in pediatric care.

The history should include the chief complaint, history of present illness, past medical history, birth history when relevant, immunization status, medication use, allergies, family history, social history, environmental exposures, and review of symptoms.

The chief complaint may be cough, wheezing, shortness of breath, chest pain, fever, noisy breathing, poor feeding, apnea, exercise intolerance, or a known diagnosis such as asthma, cystic fibrosis, pneumonia, bronchiolitis, or congenital heart disease.

The clinician should ask when symptoms began, whether they are improving or worsening, what triggers them, what treatments have been tried, and how the child responded. Feeding difficulty, decreased urine output, lethargy, irritability, poor sleep, cyanosis, retractions, and decreased activity can all indicate significant illness.

Environmental history is especially important. Tobacco smoke exposure, mold, pets, allergens, sick contacts, daycare attendance, travel, poor indoor air quality, and exposure to respiratory infections may contribute to symptoms.

Family history may reveal asthma, cystic fibrosis, allergies, immune disorders, congenital heart disease, or other inherited conditions. Social history may identify barriers to care, medication access, nutrition concerns, or environmental risks.

Pediatric Physical Examination

The pediatric pulmonary examination includes inspection, palpation, percussion, and auscultation. The approach should be age-appropriate and should minimize distress, because crying and agitation can change respiratory rate, breath sounds, and oxygen saturation.

Inspection begins by observing the child’s general appearance. A clinician should note whether the child is alert, playful, sleepy, irritable, anxious, or difficult to arouse. Mental status can provide important clues about oxygenation, ventilation, perfusion, and illness severity.

The clinician should assess respiratory rate, pattern, posture, work of breathing, chest shape, retractions, nasal flaring, accessory muscle use, and the relationship between chest and abdominal movement. Tripod positioning, inability to speak, poor feeding, grunting, or exhaustion can suggest severe distress.

Palpation can help assess chest expansion, tenderness, symmetry, and tactile fremitus. Percussion may help identify hyperinflation, dullness, or asymmetry. Hyperresonance can occur with air trapping or pneumothorax. Dullness may suggest consolidation, atelectasis, or pleural effusion.

Auscultation evaluates breath sounds, air movement, and adventitious sounds. Wheezing suggests lower airway obstruction, such as asthma or bronchiolitis. Stridor suggests upper airway obstruction. Crackles may be associated with fluid, atelectasis, pneumonia, or interstitial disease. Diminished breath sounds may indicate poor aeration, severe obstruction, pleural effusion, pneumothorax, or fatigue.

Note: The pattern of findings helps determine whether the problem is upper airway obstruction, lower airway obstruction, parenchymal lung disease, pleural disease, cardiovascular disease, or a nonpulmonary problem.

Recognizing Upper and Lower Airway Problems

Upper airway obstruction often produces stridor, a harsh, high-pitched sound most commonly heard during inspiration. It may be associated with croup, epiglottitis, foreign body aspiration, airway swelling, vocal cord dysfunction, or congenital airway abnormalities.

Croup, also called laryngotracheobronchitis, often affects young children and may present with barking cough, hoarseness, inspiratory stridor, and respiratory distress. It is usually slower in onset than epiglottitis and may show subglottic narrowing, sometimes called the steeple sign, on imaging.

Epiglottitis is a medical emergency. It may present with abrupt onset of fever, drooling, difficulty swallowing, muffled voice, stridor, anxiety, and a toxic appearance. A child suspected of having epiglottitis should remain upright and comfortable. The airway should not be manipulated unnecessarily because agitation or improper positioning can worsen obstruction.

Lower airway obstruction often produces wheezing, prolonged exhalation, air trapping, increased work of breathing, and diminished airflow. Common causes include asthma, bronchiolitis, cystic fibrosis, and airway compression. Severe obstruction may produce very quiet breath sounds, which can be more concerning than loud wheezing because it may indicate poor air movement.

Nonpulmonary Assessment

Respiratory symptoms in infants and children are not always caused by primary lung disease. Cardiac, neurologic, metabolic, infectious, gastrointestinal, and musculoskeletal disorders can all affect breathing.

Cardiac disease may present with tachypnea, poor feeding, sweating during feeds, cyanosis, hepatomegaly, poor growth, weak pulses, or poor perfusion. Neurologic disease may cause weak respiratory effort, poor airway protection, abnormal tone, or apnea. Metabolic disorders may produce abnormal breathing patterns, acidosis, lethargy, or poor feeding.

Gastroesophageal reflux can contribute to cough, wheezing, aspiration, or recurrent respiratory symptoms. Infection may present with fever, lethargy, poor perfusion, apnea, or respiratory distress. Musculoskeletal abnormalities can restrict chest expansion or impair ventilation.

Note: For this reason, a complete assessment should not focus only on the lungs. The clinician must evaluate the whole patient.

Laboratory and Diagnostic Assessment

Diagnostic tests help confirm clinical findings and guide treatment. Common studies include pulse oximetry, blood gas analysis, complete blood count, blood cultures, electrolytes, glucose, chest radiography, airway imaging, and cardiopulmonary monitoring.

Pulse oximetry is widely used in neonatal and pediatric care, but it must be interpreted with the full clinical picture. A saturation value does not replace assessment of respiratory effort, perfusion, mental status, breath sounds, and ventilation.

Blood gas analysis can provide information about oxygenation, ventilation, and acid-base balance. Capillary blood gases may be used in neonates, but accuracy depends on proper sampling technique. Arterial blood gases may be needed when more precise oxygenation and ventilation data are required.

Chest imaging may help evaluate pneumonia, atelectasis, hyperinflation, pneumothorax, pleural effusion, airway narrowing, or congenital abnormalities. Lateral neck radiographs may help assess suspected upper airway obstruction, but imaging should never delay airway protection in an unstable child.

Assessment During Respiratory Support

Assessment continues after oxygen therapy, CPAP, noninvasive ventilation, or mechanical ventilation is started. The respiratory therapist must monitor the patient’s clinical status, vital signs, oxygenation, ventilation, work of breathing, breath sounds, and response to therapy.

For mechanically ventilated neonatal and pediatric patients, routine monitoring should include physiologic assessment, ventilator settings, delivered tidal volume, pressures, alarms, patient-ventilator synchrony, humidification, airway patency, secretion burden, and signs of complications.

Humidification is especially important. Inadequate humidification can cause thick secretions, mucus plugging, airway obstruction, and increased work of breathing. Artificial airways bypass the natural warming and humidifying function of the upper airway, so humidification must be assessed regularly.

The clinician should also evaluate readiness for extubation. Common considerations include stable vital signs, acceptable oxygenation, FiO₂ requirement of 0.40 or less, adequate spontaneous respiratory rate, absence of significant apnea or periodic breathing, normal or improving work of breathing, manageable secretions, ability to protect the airway, minimal sedation, SpO₂ greater than 90%, and spontaneous tidal volume greater than 4 to 5 mL/kg.

Note: Because infants and children can deteriorate quickly, trend assessment is essential. A single normal value may not be reassuring if the overall trend is worsening.

Communication and Documentation

Clear communication is a vital part of neonatal and pediatric assessment. The respiratory therapist must document objective findings, changes in condition, interventions performed, patient response, and concerns that require follow-up.

Important details include respiratory rate, heart rate, oxygen saturation, breath sounds, work of breathing, retractions, grunting, nasal flaring, color, perfusion, mental status, ventilator settings, oxygen delivery device, blood gas results, and response to treatment.

Communication should be specific. Instead of saying that a child “looks worse,” the clinician should describe the findings, such as increased retractions, respiratory rate rising from 42 to 68 breaths/min, new grunting, oxygen saturation falling despite increased FiO₂, or diminished breath sounds on one side.

Note: This type of communication helps the healthcare team respond quickly and make appropriate decisions.

The maximal benefit is usually achieved about 24 to 48 hours after administration.

28. What is respiratory distress syndrome in a premature infant?
Respiratory distress syndrome is a condition caused by surfactant deficiency and immature lungs, leading to alveolar collapse, poor compliance, and increased work of breathing.

29. When does surfactant production become more adequate in fetal development?
Surfactant production increases significantly during the third trimester and is usually more adequate by about 34 to 36 weeks of gestation.

30. What happens when a newborn does not have enough surfactant?
The alveoli become unstable and collapse more easily, resulting in decreased lung compliance, atelectasis, hypoxemia, and respiratory distress.

31. Which condition is most strongly associated with prematurity and surfactant deficiency?
Respiratory distress syndrome is most strongly associated with prematurity and surfactant deficiency.

32. What respiratory problems are post-term infants at increased risk for?
Post-term infants are at increased risk for meconium aspiration, persistent pulmonary hypertension of the newborn, and perinatal asphyxia.

33. What should be done if a newborn is delivered through meconium-stained fluid but is vigorous?
If the newborn has good tone, strong respiratory effort, and an adequate heart rate, routine care and observation are appropriate.

34. What are common signs of respiratory distress in a newborn?
Common signs include tachypnea, nasal flaring, retractions, grunting, cyanosis, poor feeding, and decreased activity.

35. Why does grunting occur in a newborn with respiratory distress?
Grunting helps maintain positive pressure during exhalation, which may improve functional residual capacity and help keep alveoli open.

36. What does nasal flaring indicate in an infant?
Nasal flaring indicates increased work of breathing and an attempt to decrease airway resistance.

37. What does the presence of retractions indicate in a newborn?
Retractions indicate increased work of breathing and may suggest decreased lung compliance, airway obstruction, or respiratory distress.

38. Why are newborns more prone to visible retractions than adults?
Newborns have a more compliant chest wall, so increased inspiratory effort can pull the chest inward more easily.

39. What is the normal breathing pattern of many neonates?
Neonates often breathe rapidly and irregularly, with periodic breathing that may include brief pauses.

40. What is periodic breathing?
Periodic breathing is an irregular breathing pattern with brief pauses that can be normal in neonates, especially premature infants, if the pauses are short and not associated with bradycardia or desaturation.

41. Why are young infants often described as obligate nose breathers?
Young infants primarily breathe through the nose, which makes nasal obstruction more clinically significant.

42. What are normal breath sounds in infants often described as?
Normal infant breath sounds are often louder and more bronchovesicular than adult breath sounds because of a smaller chest and thinner chest wall.

43. What adventitious breath sound is commonly associated with pulmonary edema?
Fine crackles may be heard with pulmonary edema.

44. What does stridor usually indicate in a pediatric patient?
Stridor usually indicates upper airway obstruction.

45. What do wheezes usually indicate in a pediatric patient?
Wheezes usually indicate narrowing or obstruction of the lower airways.

46. What does decreased or absent breath sounds on one side suggest?
Decreased or absent breath sounds on one side may suggest pneumothorax, atelectasis, pleural effusion, foreign body obstruction, or mainstem intubation.

47. What is the most important part of the neonatal physical examination?
Inspection is the most important part because it provides immediate information about breathing effort, color, tone, activity, and overall distress.

48. What should be observed during inspection of a pediatric patient’s chest?
The clinician should observe respiratory rate, chest symmetry, work of breathing, retractions, nasal flaring, chest shape, color, posture, and level of alertness.

49. What chest wall abnormalities may be seen during pediatric inspection?
Chest wall abnormalities may include pectus excavatum, pectus carinatum, scoliosis, asymmetrical expansion, or abnormal chest movement.

50. What should be assessed during palpation of a pediatric patient?
Palpation may assess tracheal position, chest expansion, tenderness, pulses, capillary refill, and tactile fremitus when age appropriate.

51. Why is palpation for tactile fremitus less useful in infants?
It is less useful because infants cannot reliably cooperate with vocalization, and their small chest size limits the usefulness of the finding.

52. What does increased tactile fremitus over one lung region suggest?
Increased tactile fremitus may suggest pulmonary consolidation.

53. What does decreased tactile fremitus suggest?
Decreased tactile fremitus may suggest pleural effusion, pneumothorax, or airway obstruction.

54. What does a normal percussion note over the lungs sound like?
A normal lung percussion note is resonant.

55. What does a dull percussion note over a lung region suggest?
Dullness may suggest atelectasis, consolidation, or pleural effusion.

56. What condition would not typically cause a dull percussion note?
Pneumothorax would not typically cause dullness because it is more commonly associated with hyperresonance.

57. What does hyperresonance on percussion suggest?
Hyperresonance may suggest air trapping or pneumothorax.

58. When is percussion usually more useful in children?
Percussion is usually more useful in older infants and children than in very young infants.

59. What is a normal capillary refill time in infants and children?
Normal capillary refill is generally 2 seconds or less.

60. What does a capillary refill time longer than 3 seconds suggest?
A prolonged capillary refill time may suggest poor perfusion, decreased cardiac output, hypovolemia, or shock.

61. Where is the pulse commonly assessed in an infant?
The brachial pulse is commonly assessed in an infant, especially during emergency evaluation.

62. What skin finding may suggest poor perfusion in an infant?
Mottling, which appears as irregular areas of pale and dusky skin, may suggest poor perfusion or hemodynamic instability.

63. What does abdominal distention do to breathing in an infant?
Abdominal distention can impair diaphragmatic movement and increase the work of breathing.

64. What is the preferred method of routine suctioning for a newborn when needed?
A bulb syringe or mechanical suction with appropriate pressure may be used to clear the mouth and nose when secretions obstruct breathing.

65. What is the correct general sequence when suctioning a newborn’s mouth and nose?
The mouth is usually suctioned before the nose to reduce the risk of aspiration if the infant gasps.

66. What pediatric airway feature makes airway obstruction more likely?
A smaller airway diameter makes pediatric patients more vulnerable to obstruction from edema, secretions, or foreign bodies.

67. What is the narrowest portion of the pediatric airway in young children?
Traditionally, the cricoid region is considered the narrowest portion of the airway in infants and young children.

68. Why can airway swelling be dangerous in infants and children?
Even a small amount of swelling can significantly increase airway resistance because the pediatric airway is narrow.

69. Why is airway assessment of a ventilated newborn challenging?
The newborn has a short trachea, small airway diameter, compliant chest wall, and limited reserve, so tube position and ventilation can change quickly.

70. What may sudden unilateral breath sounds suggest in an intubated infant?
Sudden unilateral breath sounds may suggest right mainstem intubation, pneumothorax, atelectasis, or obstruction of one lung.

71. What does a preductal and postductal oxygen saturation difference suggest?
A significant difference between right-hand and lower-extremity saturation may suggest right-to-left shunting, persistent pulmonary hypertension, or ductal-dependent circulation.

72. Where is preductal pulse oximetry measured in a newborn?
Preductal pulse oximetry is measured on the right hand or right wrist.

73. Where is postductal pulse oximetry measured in a newborn?
Postductal pulse oximetry is measured on either foot.

74. A newborn has a right wrist SpO2 of 96% and a foot SpO2 of 85% on room air. What does this suggest?
This suggests significant right-to-left shunting, which may occur with persistent pulmonary hypertension or shunting through a patent ductus arteriosus.

75. What should happen to oxygen saturation during the first several minutes after birth?
Oxygen saturation should gradually rise after birth rather than immediately reaching normal adult values.

76. Why should oxygen therapy in premature infants be carefully monitored?
Excessive oxygen exposure can contribute to oxygen toxicity and retinopathy of prematurity.

77. What disorder can develop in premature infants exposed to excessively high oxygen levels?
Retinopathy of prematurity can develop when premature infants are exposed to excessive oxygen levels.

78. What is the main physiologic factor needed for accurate transcutaneous monitoring?
Adequate peripheral perfusion is needed for accurate transcutaneous monitoring.

79. What should the respiratory therapist do if a transcutaneous electrode is placed on the upper chest of a neonate?
The therapist should continue monitoring if the site is appropriate and the skin is intact, because the upper chest is an acceptable placement site.

80. Why must transcutaneous electrode sites be changed regularly?
Sites must be changed regularly to reduce the risk of skin burns or irritation from the heated electrode.

81. Why is a heel-stick capillary sample unreliable for assessing oxygenation?
Capillary blood PO2 does not correlate well with arterial PO2, so a heel-stick sample is not reliable for assessing oxygenation.

82. Which blood gas value differs the most between arterial and capillary samples?
PO2 differs the most and is the least reliable value in capillary blood gas sampling.

83. What condition can adversely affect the correlation between arterial and capillary blood gas results?
Hypotension or poor perfusion can reduce the accuracy of capillary blood gas results.

84. What should be used to reduce pain during a blood sample procedure in a premature infant?
A pacifier dipped in 24% sucrose may be used to help reduce procedural pain in a premature infant.

85. What is one of the most frequently performed blood tests in newborn infants?
Blood glucose testing is frequently performed because neonatal hypoglycemia can cause serious neurologic injury.

86. What are common causes of neonatal hypoglycemia?
Common causes include prematurity, infection, maternal diabetes with neonatal hyperinsulinemia, poor feeding, and low glycogen stores.

87. What does leukocytosis in an infant suggest?
Leukocytosis means an elevated white blood cell count and may suggest infection, stress, inflammation, crying, or temperature instability.

88. What imaging views are commonly used for infant chest radiographs?
An anteroposterior chest radiograph is commonly used, and a lateral view may be obtained when needed.

89. What are common indications for a chest radiograph in an infant?
Indications include unexplained tachypnea, cyanosis, abnormal breath sounds, suspected airway or chest abnormality, severe illness, or mechanical ventilation.

90. What does transillumination help detect in a newborn?
Transillumination can help detect a pneumothorax, especially in small or unstable newborns.

91. What does a small halo around the light source suggest during transillumination?
A small halo suggests a normal finding.

92. What does it suggest if an infant’s entire hemithorax lights up during transillumination?
It suggests a significant pneumothorax on that side.

93. What pediatric condition presents with a barking cough, inspiratory stridor, and symptoms that often worsen when the child is upset?
Croup is the most likely condition.

94. What radiographic sign may be seen with croup?
A steeple sign may be seen on an anteroposterior neck radiograph due to subglottic narrowing.

95. What pediatric condition presents abruptly with fever, drooling, dysphagia, stridor, and little or no cough?
Epiglottitis is the most likely condition and should be treated as a medical emergency.

96. What radiographic sign may be seen with epiglottitis?
A thumb sign may be seen on a lateral neck radiograph due to a swollen epiglottis.

97. How should the airway be managed in a child with suspected epiglottitis?
The airway should be managed carefully by experienced clinicians, with preparation for controlled intubation if needed.

98. What is a common respiratory emergency in young children?
Foreign body aspiration is a common respiratory emergency in young children.

99. What assessment finding may suggest foreign body aspiration?
Sudden coughing, choking, unilateral wheezing, decreased breath sounds, or localized air trapping may suggest foreign body aspiration.

100. What are the main components of a complete neonatal or pediatric respiratory assessment?
The main components include history, inspection, palpation when appropriate, percussion when useful, auscultation, vital signs, oxygenation assessment, laboratory data, imaging, and evaluation of the patient’s response to therapy.

Final Thoughts

Neonatal and pediatric patient assessment is a continuous, age-specific process that begins before birth and continues through stabilization, physical examination, diagnostic evaluation, respiratory support, and follow-up monitoring.

In newborns, the focus is on maternal and fetal risk factors, immediate stabilization, Apgar scoring, gestational age assessment, vital signs, and early recognition of respiratory distress. In older infants and children, history-taking, focused pulmonary examination, and careful interpretation of clinical findings are essential.

Respiratory therapists must combine observation, physical findings, diagnostic data, and trends to identify deterioration early and guide safe, effective care.
