Retractions are abnormal inward movements of the soft tissues of the chest during inspiration. They occur when a person must generate greater-than-normal pressure to draw air into the lungs.
Instead of the chest expanding smoothly, areas between or around the ribs, sternum, and clavicles are pulled inward with each breath.
Retractions are an important sign of increased work of breathing and may indicate airway obstruction, reduced lung compliance, or respiratory distress. They are especially significant in infants and children, whose respiratory conditions can worsen quickly.
What Are Retractions?
Retractions are visible inward movements of the chest wall or nearby soft tissues during inhalation. They develop when the pressure inside the chest becomes strongly negative as the patient attempts to pull air into the lungs.
During normal breathing, the diaphragm contracts and moves downward, while the rib cage expands outward. This enlarges the thoracic cavity and creates the pressure difference needed for air to enter the lungs. The chest and abdomen usually move in a smooth, coordinated pattern without obvious strain.
When airflow is restricted or the lungs are difficult to expand, the inspiratory muscles must contract more forcefully. The stronger effort creates a larger drop in intrathoracic pressure. Flexible tissues between and around the bony structures of the chest are then pulled inward, producing retractions.
Retractions are not a disease. They are a physical sign that breathing is requiring more effort than normal. Their presence should prompt an assessment of the underlying cause, the severity of respiratory distress, and the patient’s ability to maintain ventilation.
A healthy person at rest should not display noticeable retractions. Mild inward movement may occasionally occur during vigorous exercise, particularly in thin individuals, because breathing effort rises substantially. Retractions in a resting patient, however, are considered abnormal.
Why Retractions Occur
The basic mechanism of retractions involves the relationship between airflow, lung expansion, chest-wall structure, and intrathoracic pressure.
During quiet inspiration, the respiratory muscles create enough negative pressure to move air through open airways and inflate compliant lungs. When either airflow resistance rises or lung compliance falls, more pressure is required.
Two major mechanical problems commonly produce retractions:
- Increased airway resistance
- Decreased lung compliance
Note: In some patients, both problems occur at the same time.
Increased Airway Resistance
Airway resistance is the opposition encountered as air moves through the respiratory passages. Resistance increases when the airway becomes narrowed, inflamed, obstructed, or filled with secretions.
Possible causes include:
- Bronchospasm
- Airway swelling
- Thick mucus
- Foreign-body obstruction
- Structural narrowing
- Tumors or external compression
- Upper-airway inflammation
- Dynamic airway collapse
As the airway becomes narrower, the patient must create a greater pressure difference to move air through it. This increased inspiratory force pulls the soft tissues of the chest inward.
Upper-airway obstruction may produce prominent suprasternal, supraclavicular, and intercostal retractions. Lower-airway obstruction may cause intercostal and subcostal retractions, often accompanied by wheezing and prolonged expiration.
Decreased Lung Compliance
Lung compliance refers to how easily the lungs expand in response to pressure. Healthy lungs inflate with relatively little effort. Stiff lungs require more force to produce the same change in volume.
Conditions that reduce compliance include:
- Pneumonia
- Pulmonary edema
- Atelectasis
- Acute respiratory distress syndrome
- Neonatal respiratory distress syndrome
- Pulmonary fibrosis
- Alveolar inflammation
- Surfactant deficiency
When the lungs resist expansion, the inspiratory muscles must generate stronger negative pressure. The chest wall may then be pulled inward even though the ribs are attempting to expand outward.
Patients with reduced compliance often breathe rapidly and shallowly. This pattern helps limit the effort required for each individual breath, although the total work of breathing may still be high.
Increased Work of Breathing
The work of breathing is the energy required to move air into and out of the lungs. Under normal resting conditions, this work is low. Inspiration is active, while exhalation is usually passive.
When resistance increases or compliance decreases, the respiratory muscles must work harder. The patient may recruit accessory muscles, increase the respiratory rate, and alter the breathing pattern.
Retractions are one visible result of this increased workload. They may occur with:
- Tachypnea
- Nasal flaring
- Grunting
- Accessory-muscle use
- Tracheal tugging
- Head bobbing
- Paradoxical breathing
- Diaphoresis
- Agitation or restlessness
Note: The more pronounced and widespread the retractions become, the greater the patient’s respiratory effort usually is.
Types of Retractions
Retractions are classified according to where the soft tissues move inward. More than one type may be present in the same patient.
Intercostal Retractions
Intercostal retractions occur between the ribs. During inspiration, the ribs move outward while the tissues between them are pulled inward.
These retractions may be easy to observe in:
- Infants
- Young children
- Thin adults
- Patients with severe respiratory distress
Note: Intercostal retractions may occur with both obstructive and restrictive respiratory disorders. Mild intercostal retractions can indicate early distress, while deep retractions involving multiple spaces suggest greater respiratory effort.
Subcostal Retractions
Subcostal retractions appear below the lower margin of the rib cage. The soft tissue beneath the ribs moves inward during inspiration.
They are frequently observed in infants and young children because their chest walls are flexible. Subcostal retractions may be associated with bronchiolitis, pneumonia, asthma, respiratory distress syndrome, and other conditions that increase breathing effort.
Suprasternal Retractions
Suprasternal retractions occur in the soft tissue above the sternum, near the base of the neck. This area sinks inward as the patient inhales.
Suprasternal retractions are often associated with substantial inspiratory effort and may be prominent in upper-airway obstruction. They may occur with stridor, hoarseness, a barking cough, or other signs of narrowed airflow above the thorax.
Supraclavicular Retractions
Supraclavicular retractions occur above the clavicles. The tissues in these areas are pulled inward during inspiration.
These retractions generally indicate significant respiratory effort and are often accompanied by neck-muscle activity. They may be seen in severe airway obstruction, advanced lung disease, or acute respiratory failure.
Substernal and Subxiphoid Retractions
Substernal retractions occur below the sternum. When the inward movement is most visible near the lower tip of the sternum, it may be described as subxiphoid or xiphoid retraction.
These findings are particularly important in neonatal assessment. Xiphoid retractions are included in respiratory-distress scoring systems used for premature infants and newborns.
Tracheal Tugging
Tracheal tugging is related to retractions but involves downward movement of the tracheal structures or thyroid cartilage during inspiration.
It may occur when the patient uses the sternocleidomastoid muscles forcefully to elevate the upper chest. This downward movement indicates that the patient is generating strong inspiratory pressure and recruiting accessory muscles.
Note: Tracheal tugging may be difficult to observe in patients with obesity or a short neck.
Retractions in Infants and Children
Retractions are especially common and clinically important in infants and young children. Their chest walls are more compliant than those of adults, which means the ribs and surrounding tissues are softer and more flexible.
When an infant generates strong negative pressure during inspiration, the chest wall is more easily pulled inward. Small airways and limited respiratory reserve also make young patients vulnerable to rapid deterioration.
Even a small amount of airway swelling or mucus can greatly increase resistance in an infant. Because resistance rises sharply as airway diameter decreases, minor narrowing may create significant breathing difficulty.
Why Infants Are More Vulnerable
Several anatomical and physiological features increase the risk of retractions in infants:
- Small airway diameter
- Flexible chest wall
- Horizontally positioned ribs
- Limited respiratory-muscle endurance
- Higher oxygen consumption
- Lower respiratory reserve
- Greater dependence on the diaphragm
- Immature lungs in premature infants
Note: Infants may maintain oxygenation temporarily by breathing rapidly and working harder. However, respiratory muscles can fatigue quickly. This makes repeated assessment essential.
Signs That May Accompany Retractions
Retractions in infants should be evaluated with other signs of respiratory distress, including:
- Tachypnea
- Nasal flaring
- Expiratory grunting
- Cyanosis
- Apnea
- Head bobbing
- Poor feeding
- Reduced air entry
- Abnormal breath sounds
- See-saw breathing
- Irritability
- Lethargy
The combination of grunting, nasal flaring, and retractions is a classic pattern of neonatal respiratory distress.
Grunting is an attempt to maintain pressure in the alveoli at the end of expiration. Nasal flaring widens the nostrils to reduce resistance at the entrance to the airway. Retractions indicate that the infant is generating additional inspiratory pressure.
Retractions in Premature Infants
Premature infants are at increased risk because their lungs and chest walls are immature. Surfactant deficiency is a major concern.
Surfactant reduces surface tension inside the alveoli. When surfactant is insufficient, the alveoli are more likely to collapse during exhalation. This lowers lung volume, reduces compliance, and impairs gas exchange.
The infant must generate stronger pressure to reopen and stabilize the alveoli. Visible intercostal, subcostal, and xiphoid retractions may occur with each breath.
Other common findings include:
- Rapid, shallow breathing
- Expiratory grunting
- Nasal flaring
- Diminished breath sounds
- Cyanosis
- Reduced chest expansion
- Increased oxygen requirement
Note: As the condition worsens, apnea, bradycardia, poor perfusion, and altered responsiveness may develop.
The Silverman-Anderson Score
The Silverman-Anderson scoring system is used to evaluate respiratory distress in newborns, especially premature infants. It converts visible clinical signs into a numerical score that can be tracked over time.
The system evaluates five areas:
- Upper-chest movement
- Lower-chest retractions
- Xiphoid retractions
- Nasal flaring
- Expiratory grunting
Each category receives a score of 0, 1, or 2.
A score of 0 indicates no abnormality. A score of 1 represents a moderate finding. A score of 2 represents a marked abnormality.
For intercostal and xiphoid retractions:
- 0 indicates no retractions
- 1 indicates retractions are just visible
- 2 indicates marked retractions
The total score ranges from 0 to 10. Higher scores indicate more severe respiratory distress. A score of 0 suggests no distress. Scores from 1 through 6 generally indicate mild to moderate distress. A score of 7 or greater may indicate severe distress and possible respiratory failure.
Note: The score should be interpreted alongside oxygen saturation, respiratory rate, blood gases, perfusion, mental status, and the infant’s response to treatment.
Conditions That Cause Retractions
Retractions can occur with many respiratory disorders. They do not identify one specific disease. Instead, they reveal that the patient is struggling against increased resistance, reduced compliance, or another mechanical limitation.
Croup
Croup causes inflammation and narrowing of the larynx and subglottic airway. It commonly affects young children.
Typical findings include:
- Barking cough
- Inspiratory stridor
- Hoarseness
- Tachypnea
- Suprasternal retractions
- Intercostal retractions
- Subcostal retractions
Retractions may worsen when the child cries or becomes agitated because respiratory demand rises. Severe obstruction may produce reduced air entry, cyanosis, lethargy, or decreasing stridor as airflow becomes critically limited.
Note: A child with significant retractions and stridor at rest requires urgent evaluation.
Epiglottitis
Epiglottitis is a dangerous form of upper-airway inflammation that may cause rapid airway obstruction.
Possible findings include:
- High fever
- Severe sore throat
- Difficulty swallowing
- Drooling
- Muffled voice
- Stridor
- Suprasternal retractions
- Intercostal retractions
- Tripod positioning
- Anxiety or air hunger
The patient may prefer to sit upright and lean forward. Unnecessary examination of the throat can increase agitation and worsen obstruction.
Note: Retractions in this setting may indicate a life-threatening airway emergency.
Bronchiolitis
Bronchiolitis is a lower-airway infection that commonly affects infants. Inflammation, edema, mucus, and cellular debris narrow the small airways.
Clinical findings may include:
- Tachypnea
- Wheezing
- Crackles
- Nasal flaring
- Intercostal retractions
- Subcostal retractions
- Poor feeding
- Apnea in young infants
- Hypoxemia
Note: Because infant airways are already small, limited swelling can substantially increase resistance. Air trapping and atelectasis may develop, further increasing the work of breathing.
Asthma
Asthma causes reversible airway narrowing through bronchospasm, inflammation, and mucus production.
During a significant asthma attack, the patient may develop:
- Wheezing
- Prolonged expiration
- Tachypnea
- Accessory-muscle use
- Intercostal retractions
- Supraclavicular retractions
- Difficulty speaking
- Anxiety
- Reduced air entry
Severe retractions indicate that the patient is using considerable force to breathe. A decrease in wheezing is not always reassuring. If breath sounds become very quiet while distress continues, airflow may be critically reduced.
Fatigue, altered mental status, worsening oxygenation, and a silent chest are signs of impending respiratory failure.
Pneumonia
Pneumonia may reduce lung compliance through inflammation, fluid accumulation, and alveolar filling.
Patients may develop:
- Fever
- Cough
- Tachypnea
- Crackles
- Hypoxemia
- Retractions
- Chest discomfort
- Reduced air entry
- Grunting in infants
Note: Infants may show poor feeding, irritability, lethargy, nasal flaring, and cyanosis rather than a strong cough. Retractions suggest that lung expansion or gas exchange has become difficult enough to increase respiratory effort.
Acute Respiratory Distress Syndrome
Acute respiratory distress syndrome (ARDS) causes widespread inflammation, alveolar injury, pulmonary edema, atelectasis, and severe hypoxemia.
The lungs become stiff and difficult to inflate. Patients may develop:
- Rapid, shallow breathing
- Intercostal retractions
- Supraclavicular retractions
- Nasal flaring
- Accessory-muscle use
- Cyanosis
- Marked hypoxemia
- Fatigue
Note: Retractions occur because the patient must generate considerable inspiratory force to inflate poorly compliant lungs.
Pulmonary Edema
Pulmonary edema causes fluid to accumulate within the lung tissues and alveoli. This reduces compliance and interferes with gas exchange.
Possible findings include:
- Dyspnea
- Tachypnea
- Crackles
- Hypoxemia
- Retractions
- Frothy sputum
- Anxiety
- Diaphoresis
Note: As breathing becomes more difficult, the patient may recruit accessory muscles and develop visible inward chest movement.
Atelectasis
Atelectasis is the collapse of part or all of a lung region. It reduces the amount of ventilated lung tissue and may decrease compliance. Retractions may occur when the patient attempts to expand collapsed alveoli or compensate for lost lung volume.
Other findings may include:
- Reduced breath sounds
- Tachypnea
- Hypoxemia
- Asymmetric chest movement
- Dullness to percussion
- Increased respiratory effort
Meconium Aspiration Syndrome
Meconium aspiration syndrome occurs when a newborn inhales meconium-contaminated fluid. Meconium can obstruct the airways, cause inflammation, and impair surfactant function.
The infant may develop:
- Gasping respirations
- Tachypnea
- Grunting
- Nasal flaring
- Retractions
- Cyanosis
- Abnormal breath sounds
Note: Partial airway obstruction may produce a ball-valve effect in which air enters but cannot escape normally. This can cause air trapping, uneven ventilation, atelectasis, and impaired gas exchange.
Bronchopulmonary Dysplasia
Bronchopulmonary dysplasia is a chronic lung disorder that primarily affects premature infants who have required oxygen therapy or positive-pressure ventilation.
Possible findings include:
- Tachypnea
- Retractions
- Crackles
- Wheezing
- Increased oxygen requirement
- Poor growth
- Feeding difficulty
Note: Structural and inflammatory changes can increase airway resistance and reduce effective lung compliance, making breathing more difficult.
Inhalation Injury
Smoke or chemical inhalation can cause swelling of the upper airway and injury to the lower respiratory tract.
Warning signs include:
- Hoarseness
- Stridor
- Wheezing
- Soot around the mouth or nose
- Facial burns
- Tachypnea
- Retractions
- Altered mental status
Note: Retractions accompanied by stridor after a burn or smoke exposure may indicate progressive airway swelling and the need for urgent airway management.
How to Assess Retractions
Assessment should begin with observation before touching or disturbing the patient. Agitation can worsen breathing effort, especially in children with upper-airway obstruction.
The patient should be positioned so the chest, abdomen, neck, and clavicular areas can be observed.
Identify the Location
Determine whether retractions are:
- Intercostal
- Subcostal
- Suprasternal
- Supraclavicular
- Substernal
- Xiphoid
Note: Multiple areas may be involved in severe distress.
Estimate the Severity
Retractions may be described as:
- Mild
- Moderate
- Severe
- Just visible
- Marked
- Localized
- Widespread
Note: Mild retractions may involve shallow inward movement in one region. Severe retractions are deeper, involve several regions, and are often accompanied by accessory-muscle use.
Observe the Respiratory Pattern
Assess:
- Respiratory rate
- Rhythm
- Depth
- Chest symmetry
- Chest-abdominal coordination
- Inspiratory-to-expiratory pattern
- Presence of apnea
- Presence of paradoxical movement
Rapid breathing is common in early distress. A slowing respiratory rate in a patient who remains visibly ill may indicate fatigue.
See-saw breathing occurs when the chest and abdomen move in opposite directions. This abnormal pattern is especially concerning in infants.
Listen to Breath Sounds
Breath sounds may help identify the cause.
- Stridor suggests upper-airway obstruction.
- Wheezing suggests lower-airway narrowing.
- Crackles may indicate fluid, inflammation, or atelectasis.
- Diminished sounds may indicate severe obstruction or reduced ventilation.
- Unilateral absent sounds may suggest pneumothorax, mainstem obstruction, or another localized problem.
Note: Breath sounds should be compared on both sides of the chest.
Assess Oxygenation
Pulse oximetry provides useful information, but oxygen saturation should not be used alone to judge severity.
A patient may maintain an acceptable saturation temporarily through intense respiratory effort. Significant retractions may therefore appear before oxygen saturation falls.
Assess:
- Oxygen saturation
- Skin color
- Mucous membrane color
- Oxygen requirement
- Capillary refill
- Heart rate
Note: Central cyanosis is a late and concerning sign.
Evaluate Mental Status
Changes in mental status may indicate hypoxemia, hypercapnia, exhaustion, or reduced cerebral perfusion.
Warning signs include:
- Agitation
- Restlessness
- Anxiety
- Confusion
- Reduced responsiveness
- Lethargy
- Poor muscle tone
Note: A child who becomes quiet after prolonged respiratory distress may be tiring rather than improving.
Signs of Impending Respiratory Failure
Retractions initially show that the patient is still generating forceful respiratory effort. If the muscles fatigue, the patient may no longer be able to produce prominent retractions.
A sudden reduction in retractions is concerning when accompanied by:
- Reduced chest movement
- Slower breathing
- Shallow respirations
- Poor air entry
- Altered mental status
- Cyanosis
- Apnea
- Bradycardia
- Weak cry
- Inability to speak
- Decreasing oxygen saturation
- Rising carbon dioxide levels
Note: The disappearance of retractions is reassuring only when the patient’s overall respiratory condition improves.
Treatment of Retractions
Treatment is directed at the underlying cause. Retractions themselves are not treated as an isolated problem. Immediate priorities include maintaining the airway, supporting oxygenation and ventilation, and reducing respiratory muscle workload.
Supplemental Oxygen
Oxygen may be administered when hypoxemia is present. The delivery method depends on the patient’s age, condition, and oxygen requirement.
Possible devices include:
- Nasal cannula
- Simple mask
- Air-entrainment mask
- Nonrebreather mask
- Oxygen hood
- High-flow nasal cannula
Note: Oxygen can improve saturation, but it does not necessarily correct airway obstruction, reduced compliance, or inadequate ventilation.
Airway Management
Airway patency must be evaluated promptly.
Interventions may include:
- Repositioning
- Suctioning secretions
- Removing a visible obstruction
- Administering medications for swelling
- Providing humidification
- Preparing for advanced airway placement
Note: Patients with severe upper-airway obstruction should be kept calm. Forced positioning and unnecessary procedures may worsen obstruction.
Bronchodilator Therapy
Bronchodilators may be used when bronchospasm contributes to airflow obstruction, such as during an asthma attack.
Improvement may be reflected by:
- Reduced wheezing
- Better air entry
- Lower respiratory rate
- Less accessory-muscle use
- Reduced retractions
- Improved ability to speak
Note: A patient who does not improve requires further evaluation and possibly more aggressive support.
Anti-Inflammatory Treatment
Corticosteroids or other anti-inflammatory medications may be used when airway inflammation contributes to the problem. Examples include asthma and croup. The exact treatment depends on the diagnosis, severity, and clinical setting.
Continuous Positive Airway Pressure
Continuous positive airway pressure can help keep airways and alveoli open. It may increase functional residual capacity, improve oxygenation, reduce alveolar collapse, and decrease inspiratory workload.
It is commonly used in neonatal respiratory distress and selected pediatric or adult patients. A reduction in retractions after continuous positive airway pressure may indicate improved lung expansion and reduced respiratory-muscle load.
High-Flow Nasal Cannula
High-flow nasal cannula provides heated, humidified gas at higher flow rates. It may reduce inspiratory resistance, decrease dead-space rebreathing, provide a small amount of positive pressure, and improve comfort.
It is often used in infants with bronchiolitis and other forms of respiratory distress.
Clinical response should be assessed through:
- Respiratory rate
- Retraction severity
- Oxygen requirement
- Heart rate
- Air entry
- Mental status
Surfactant Replacement
Premature infants with surfactant deficiency may receive surfactant replacement therapy. Surfactant helps reduce alveolar surface tension, improve lung compliance, stabilize alveoli, and decrease the pressure needed to inflate the lungs.
As lung mechanics improve, retractions and grunting may become less pronounced.
Noninvasive Positive-Pressure Ventilation
Noninvasive positive-pressure ventilation may be considered when the patient requires greater support but can still protect the airway.
It may help:
- Improve ventilation
- Improve oxygenation
- Reduce respiratory-muscle workload
- Increase tidal volume
- Decrease retractions
- Delay or prevent intubation in selected patients
Note: Close monitoring is necessary because noninvasive support may fail in patients with worsening fatigue, severe hypoxemia, altered mental status, or inability to protect the airway.
Endotracheal Intubation and Mechanical Ventilation
Severe respiratory failure may require endotracheal intubation and mechanical ventilation.
Indications may include:
- Apnea
- Gasping
- Severe fatigue
- Inadequate ventilation
- Persistent hypoxemia
- Altered mental status
- Hemodynamic instability
- Inability to protect the airway
- Failure of noninvasive support
Note: Mechanical ventilation reduces or replaces the patient’s work of breathing while the underlying condition is treated.
Monitoring the Response to Treatment
Retractions should be reassessed frequently after treatment begins.
Signs of improvement include:
- Less inward chest movement
- Fewer areas involved
- Lower respiratory rate
- Better chest expansion
- Improved breath sounds
- Reduced accessory-muscle use
- Better oxygen saturation
- Improved color
- More normal mental status
- Decreased oxygen requirement
Persistent or worsening retractions suggest that the patient remains under significant respiratory stress. A decrease in retractions should not be considered improvement unless it occurs with better ventilation, oxygenation, air entry, and alertness.
In infants, repeated respiratory-distress scores may be used to evaluate trends. A falling score suggests improvement, while a rising score indicates worsening disease or inadequate support.
Documenting Retractions
Clear documentation helps clinicians monitor changes over time and communicate the severity of respiratory distress.
Documentation may include:
- Location of retractions
- Depth or severity
- Areas involved
- Respiratory rate
- Breath sounds
- Nasal flaring
- Grunting
- Accessory-muscle use
- Oxygen saturation
- Oxygen delivery device
- Mental status
- Response to treatment
An example description might state that the patient has moderate intercostal and subcostal retractions with tachypnea, nasal flaring, and diminished bilateral air entry.
Note: Specific descriptions are more useful than simply recording that the patient has labored breathing.
Retractions and Clinical Decision-Making
Retractions should be treated as a warning sign rather than a diagnosis. Their clinical importance depends on the patient’s age, associated findings, progression, and overall stability.
Mild retractions in a stable patient may indicate compensated distress. Marked retractions involving several areas suggest a greater workload and a higher risk of fatigue.
Urgent intervention is more likely to be needed when retractions occur with:
- Stridor at rest
- Severe wheezing
- Diminished breath sounds
- Central cyanosis
- Poor feeding
- Apnea
- Bradycardia
- Altered mental status
- Hypotension
- Exhaustion
- Worsening oxygenation
Note: Repeated observation is essential because respiratory status can change quickly, especially in newborns, infants, and young children.
Retractions Practice Questions
1. What are retractions?
Retractions are visible inward movements of the soft tissues of the chest during inspiration.
2. What do retractions usually indicate?
They usually indicate increased work of breathing and possible respiratory distress.
3. Why do the soft tissues of the chest move inward during retractions?
They move inward because strong inspiratory effort creates unusually negative pressure inside the chest.

They occur in the soft tissue above the sternum near the base of the neck.
8. What are supraclavicular retractions?
Supraclavicular retractions are inward movements of the tissues above the clavicles during inspiration.
9. What are substernal retractions?
Substernal retractions occur when the tissues below the sternum are pulled inward during inhalation.
10. What is another name for retractions near the xiphoid process?
They may be called xiphoid or subxiphoid retractions.
11. What two major mechanical problems commonly cause retractions?
Increased airway resistance and decreased lung compliance commonly cause retractions.
12. How does airway narrowing contribute to retractions?
Airway narrowing forces the patient to generate greater inspiratory pressure to move air through the obstructed passage.
13. What does lung compliance describe?
Lung compliance describes how easily the lungs expand in response to pressure.
14. Why can stiff lungs cause visible retractions?
Stiff lungs require greater inspiratory force to inflate, creating enough negative pressure to pull the chest tissues inward.
15. Why are retractions more noticeable in infants?
Infants have thin, flexible, and highly compliant chest walls that are easily pulled inward during forceful inspiration.
16. Why can minor airway swelling be serious in an infant?
An infant’s airways are very small, so even limited swelling can significantly increase resistance to airflow.
17. Which three findings commonly form a pattern of neonatal respiratory distress?
Grunting, nasal flaring, and retractions commonly occur together in neonatal respiratory distress.
18. What is the purpose of expiratory grunting in an infant?
Grunting helps maintain pressure in the alveoli and preserve lung volume at the end of expiration.
19. How does nasal flaring help a patient breathe?
Nasal flaring widens the nostrils and attempts to reduce resistance at the entrance to the airway.
20. What is tracheal tugging?
Tracheal tugging is a downward movement of the tracheal structures or thyroid cartilage during inspiration.
21. What does tracheal tugging suggest?
It suggests strong inspiratory effort and forceful use of accessory respiratory muscles.
22. What is see-saw breathing?
See-saw breathing is an abnormal pattern in which the chest and abdomen move in opposite directions.
23. Why is see-saw breathing concerning in an infant?

27. What does a Silverman-Anderson score of 0 indicate?
It indicates no visible respiratory distress.
28. What does a Silverman-Anderson score of 7 or greater suggest?
It suggests severe respiratory distress and possible impending respiratory failure.
29. Why are premature infants at increased risk for retractions?
They have immature lungs, flexible chest walls, limited respiratory reserve, and may have surfactant deficiency.
30. How does surfactant deficiency contribute to retractions?
It promotes alveolar collapse and decreases lung compliance, forcing the infant to generate greater inspiratory pressure.
31. Which type of breathing pattern often occurs with reduced lung compliance?
Rapid, shallow breathing often occurs because the lungs are difficult to expand.
32. How can croup cause retractions?
Croup narrows the subglottic airway, requiring stronger inspiratory effort to draw air through the obstruction.
33. Which sound commonly accompanies retractions in croup?
Inspiratory stridor commonly accompanies retractions in croup.

Crying increases airflow demand and respiratory effort, making the obstruction more noticeable.
35. Which findings may accompany retractions in epiglottitis?
Stridor, drooling, difficulty swallowing, fever, anxiety, and tripod positioning may accompany them.
36. Why should a child with suspected epiglottitis be handled carefully?
Agitation and unnecessary airway manipulation may worsen the obstruction.
37. How does bronchiolitis produce retractions?
Inflammation, edema, mucus, and debris narrow the small airways and increase the effort needed to breathe.
38. Which retraction locations are common in bronchiolitis?
Intercostal and subcostal retractions are common.
39. How does asthma contribute to retractions?
Bronchospasm, airway inflammation, and mucus increase resistance and force the patient to breathe more forcefully.
40. What does a silent chest in a patient with severe asthma suggest?
It suggests critically reduced airflow and possible impending respiratory failure.
41. How can pneumonia cause retractions?
Inflammation and fluid in the lungs reduce compliance and make lung expansion more difficult.
42. Why may acute respiratory distress syndrome cause pronounced retractions?
It produces stiff, poorly compliant lungs that require substantial inspiratory effort to inflate.
43. How does pulmonary edema increase the work of breathing?
Fluid in the lung tissue and alveoli reduces compliance and interferes with gas exchange.
44. How can atelectasis lead to retractions?
Collapsed lung regions require increased effort to reopen and reduce the amount of lung available for ventilation.
45. Why may meconium aspiration syndrome cause chest-wall retractions?
Meconium can obstruct the airways, impair surfactant, increase resistance, and reduce lung expansion.
46. What is the ball-valve effect in meconium aspiration?
It occurs when air enters past a partial obstruction but cannot escape normally, causing air trapping.
47. How can bronchopulmonary dysplasia contribute to retractions?
Chronic airway inflammation and abnormal lung development increase resistance and reduce effective compliance.
48. Why are retractions after smoke inhalation concerning?
They may indicate progressive upper-airway swelling or lower-airway injury.
49. What should be assessed before disturbing a patient with retractions?
The clinician should first observe breathing pattern, chest movement, respiratory rate, and overall appearance.
50. Why can agitation worsen retractions in a child with airway obstruction?
Agitation increases oxygen demand, airflow requirements, and respiratory effort.
51. What should a clinician determine when first inspecting retractions?
The clinician should identify their location, depth, extent, and whether multiple areas are involved.
52. What do widespread retractions generally indicate?
They generally indicate a greater increase in work of breathing and more severe respiratory distress.
53. Why should the respiratory rate be interpreted carefully in a distressed patient?
A decreasing rate may reflect respiratory muscle fatigue rather than improvement.
54. What does stridor suggest when it occurs with retractions?
It suggests narrowing or obstruction of the upper airway.
55. What does wheezing suggest when it accompanies retractions?
It suggests narrowing of the lower airways, often from bronchospasm, inflammation, or mucus.
56. What may crackles indicate in a patient with retractions?
They may indicate fluid, inflammation, alveolar collapse, or reopening of small airways.
57. Why are diminished breath sounds concerning in a patient with severe retractions?
They may indicate that very little air is moving despite substantial respiratory effort.
58. What may unilateral absent breath sounds indicate?
They may indicate pneumothorax, mainstem bronchial obstruction, or another localized ventilation problem.
59. Can normal oxygen saturation rule out serious respiratory distress?
No. A patient may temporarily maintain oxygen saturation through extreme breathing effort.
60. Why should skin color be assessed in a patient with retractions?
Pallor, mottling, or cyanosis may indicate impaired oxygenation or circulation.
61. What does central cyanosis indicate?
It indicates significant arterial oxygen desaturation and is a serious clinical finding.
62. Why is mental status important when evaluating retractions?
Changes in alertness may indicate hypoxemia, carbon dioxide retention, exhaustion, or worsening respiratory failure.
63. Which mental-status change may appear early in respiratory distress?
Restlessness, anxiety, or agitation may appear early.
64. Which mental-status findings may suggest advanced respiratory failure?
Lethargy, confusion, poor responsiveness, and reduced muscle tone may suggest advanced failure.
65. Why can the disappearance of retractions be misleading?
A fatigued patient may lose the strength needed to produce visible retractions even though respiratory function is worsening.
66. Which findings make reduced retractions concerning rather than reassuring?
Poor chest movement, shallow breathing, diminished air entry, cyanosis, and altered mental status make the change concerning.
67. What does head bobbing indicate in an infant?
It indicates forceful accessory-muscle use and increased work of breathing.
68. Why is poor feeding an important sign in an infant with retractions?
Breathing difficulty may prevent the infant from coordinating sucking, swallowing, and breathing.
69. Why are apnea and bradycardia particularly concerning in infants?
They may indicate severe respiratory fatigue, hypoxemia, or impending respiratory failure.
70. What is the first general priority when treating a patient with retractions?
The first priority is to assess and maintain a patent airway.
71. When is supplemental oxygen indicated?
It is indicated when the patient has hypoxemia or is unable to maintain an appropriate oxygen saturation.
72. Why does oxygen therapy not always eliminate retractions?
Oxygen may improve oxygenation without correcting airway obstruction, stiff lungs, or inadequate ventilation.
73. How can suctioning reduce retractions?
Suctioning can remove obstructing secretions, improve airflow, and decrease the inspiratory effort required.
74. When may bronchodilator therapy reduce retractions?
It may reduce them when bronchospasm is contributing to lower-airway obstruction.
75. Which changes suggest a favorable response to bronchodilator therapy?
Improved air entry, reduced wheezing, a lower respiratory rate, and less accessory-muscle use suggest improvement.
76. How can continuous positive airway pressure reduce retractions?
It helps keep alveoli and airways open, improves lung volume, and decreases the inspiratory effort required to breathe.
77. What effect can high-flow nasal cannula therapy have on respiratory effort?
It may reduce inspiratory resistance, improve oxygen delivery, and decrease the severity of retractions.
78. Why must a patient on high-flow nasal cannula be reassessed frequently?
Worsening retractions, oxygen needs, or mental status may indicate that the support is inadequate.
79. How does surfactant replacement improve breathing in premature infants?
It lowers alveolar surface tension, improves lung compliance, and reduces the pressure needed to inflate the lungs.
80. When may noninvasive positive-pressure ventilation be considered?
It may be considered when a patient needs additional breathing support but can still protect the airway.
81. What are signs that noninvasive ventilation may be failing?
Worsening fatigue, severe hypoxemia, altered mental status, poor ventilation, and increasing retractions may indicate failure.
82. When may endotracheal intubation be necessary in a patient with retractions?
It may be necessary when severe fatigue, apnea, inadequate ventilation, persistent hypoxemia, or airway compromise develops.
83. How does mechanical ventilation affect the work of breathing?
It reduces or replaces the patient’s respiratory effort while the underlying condition is treated.
84. What change in retractions usually suggests improvement after treatment?
A decrease in their depth, extent, and number of affected areas usually suggests improvement.
85. What other findings should improve along with reduced retractions?
Respiratory rate, air entry, oxygenation, chest expansion, and mental status should also improve.
86. What do persistent retractions after treatment suggest?
They suggest that the underlying problem remains unresolved or that the current respiratory support is insufficient.
87. Why is repeated assessment more useful than a single observation?
Repeated assessment shows whether the patient is improving, remaining stable, or deteriorating over time.
88. What details about retractions should be documented?
Their location, severity, extent, associated signs, and response to treatment should be documented.
89. Why is the phrase “labored breathing” alone insufficient documentation?
It does not describe the specific location, severity, or associated features of the respiratory effort.
90. What is an example of specific documentation for retractions?
Moderate intercostal and subcostal retractions with tachypnea, nasal flaring, and diminished bilateral air entry.
91. Can retractions be used to diagnose a specific disease?
No. They are a clinical sign that can occur with many different respiratory conditions.
92. What determines the clinical significance of retractions?
The patient’s age, severity of the retractions, associated findings, progression, and overall condition determine their significance.
93. What may mild retractions indicate in an otherwise stable patient?
They may indicate early or compensated respiratory distress.
94. What do marked retractions involving several chest areas suggest?
They suggest severe respiratory effort and a greater risk of respiratory muscle fatigue.
95. Why are retractions with stridor at rest especially concerning?
They may indicate significant upper-airway obstruction that could progress rapidly.
96. Why are retractions with poor air movement more concerning than retractions with good air entry?
They suggest that substantial effort is producing very little ventilation.
97. How can oxygen saturation remain normal despite severe retractions?
The patient may temporarily compensate by increasing respiratory rate and muscular effort.
98. What does a rising respiratory-distress score indicate in an infant?
It indicates worsening respiratory difficulty or inadequate treatment.
99. What does a falling respiratory-distress score generally indicate?
It generally indicates reduced work of breathing and improvement in the infant’s condition.
100. What is the main clinical lesson associated with retractions?
They should be recognized as a warning sign of increased work of breathing that requires evaluation of the underlying cause and overall respiratory status.
Final Thoughts
Retractions are visible inward movements of the chest wall that indicate increased inspiratory effort. They occur when a patient generates unusually negative intrathoracic pressure to overcome airway narrowing, stiff lungs, alveolar collapse, or another respiratory problem. Their location, depth, extent, and associated findings can help estimate the severity of distress.
Retractions are especially important in infants and children because their flexible chest walls and limited respiratory reserves make them vulnerable to rapid deterioration.
Careful observation, repeated assessment, and treatment of the underlying cause are necessary to reduce breathing effort and prevent respiratory failure.
