Pediatric Pulmonary History: Structured Approach
When taking a pediatric pulmonary history, begin with the presenting respiratory symptoms (onset, duration, severity), then systematically progress through past medical history focusing on neonatal/perinatal events, family history of lung disease, environmental exposures, and growth/developmental patterns—this sequence allows you to efficiently exclude common causes while identifying red flags for serious conditions like childhood interstitial lung disease (chILD).
1. Chief Complaint and Present Illness
Start with the specific respiratory symptom(s):
Primary Symptoms to Characterize:
- Dyspnea: Onset (acute vs. chronic), severity, exertional vs. rest, positional changes
- Cough: Duration (>4 weeks = chronic), character (wet vs. dry), timing (nocturnal, with feeds), productivity
- Wheezing: Age at first episode, frequency, triggers, response to bronchodilators
- Chest pain: Location, quality, relationship to breathing
- Tachypnea or increased work of breathing: When noticed, progression
Critical Timing Questions:
- Neonatal onset (first month of life) vs. later presentation—this fundamentally changes your differential 1
- Acute vs. chronic/persistent symptoms (>3-4 weeks)
- Progressive worsening vs. stable vs. improving trend 1
2. Past Medical History (Disease Severity Assessment)
Neonatal/Perinatal History:
- Gestational age and birth weight (prematurity, bronchopulmonary dysplasia risk)
- Neonatal respiratory distress requiring ventilation or oxygen 1
- NICU admission and duration
- Meconium aspiration or other birth complications
Exclude Common "Masqueraders" 1:
- Cystic fibrosis: Newborn screening results, meconium ileus, failure to thrive, recurrent infections
- Congenital heart disease: Cyanosis, feeding difficulties, prior cardiac evaluation 1
- Immunodeficiency: Recurrent/severe infections, opportunistic organisms, HIV status 1
- Primary ciliary dyskinesia: Neonatal respiratory distress, chronic wet cough, situs abnormalities, recurrent otitis
Growth and Development:
- Failure to thrive or poor weight gain (suggests chronic hypoxemia or increased work of breathing)
- Developmental delays (may indicate chronic hypoxia)
- Exercise tolerance compared to peers
3. Family History (Critical for chILD Evaluation)
This is particularly important as it changes your diagnostic pathway 1:
- Adult ILD in family members (may suggest genetic surfactant protein mutations)
- Other family members with chILD diagnoses
- History of neonatal respiratory failure in siblings 1
- Consanguinity (increases autosomal recessive disease risk)
- Sudden infant death syndrome (SIDS) in family
The presence of a positive family history may warrant early genetic testing for surfactant protein mutations before or concurrent with other invasive testing 1.
4. Environmental and Social History
Exposures:
- Tobacco smoke exposure (household members who smoke, in utero exposure)
- Environmental allergens: Pets, mold, dust
- Occupational exposures through parents (farming, chemicals)
- Geographic location: Travel history, endemic infections
Social Context:
- Daycare attendance (infection exposure)
- Housing conditions (dampness, overcrowding)
- Access to healthcare and medications
Family history and social history are often intertwined in pediatric practice and provide holistic context 2.
5. Medication and Treatment History
- Current medications and adherence
- Previous trials: Bronchodilators, inhaled corticosteroids, antibiotics
- Response to treatments (or lack thereof)—failure to respond to standard asthma therapy should raise concern for alternative diagnoses 3
- Oxygen requirement: Current or previous, flow rates
- Previous hospitalizations or ICU admissions for respiratory issues
6. Review of Systems (Pulmonary-Focused)
Respiratory-Specific:
- Hemoptysis (rare but serious in children)
- Stridor (upper airway involvement)
- Apnea or cyanotic episodes
- Nocturnal symptoms (sleep-disordered breathing, nocturnal asthma)
Associated Systems:
- Cardiac: Cyanosis, syncope, palpitations (pulmonary hypertension is associated with worse prognosis in chILD 1)
- GI: Reflux, vomiting, aspiration risk, chronic diarrhea (CF, immunodeficiency)
- Skin: Eczema (atopic disease), rashes (connective tissue disease)
- ENT: Chronic rhinosinusitis, recurrent otitis (ciliary dyskinesia, immunodeficiency)
7. Functional Assessment
- Gas exchange abnormalities: Prior pulse oximetry readings, oxygen saturations at rest and with activity
- Activity limitation: Can the child keep up with peers? Feeding difficulties in infants?
- School absences due to respiratory illness
- Quality of life impact on child and family
Common Pitfalls to Avoid
- Don't assume all wheezing is asthma—chronic symptoms unresponsive to bronchodilators warrant broader evaluation 3
- Don't overlook cardiac causes—structural heart disease and pulmonary vascular disease can masquerade as primary lung disease 1
- Don't skip family history—it fundamentally alters the diagnostic approach in chILD 1
- Don't forget to assess disease severity objectively—symptoms alone may not correlate with functional impairment; ask about oxygen requirements and prior testing 1
Age-Specific Considerations
- Infants (<1 month): Focus heavily on neonatal history, family history, and acute vs. chronic presentation 1
- Infants (>1 month): Broaden to include feeding history, growth patterns, and developmental milestones 1
- School-age children: Exercise tolerance, school performance, peer comparisons become more relevant
- Adolescents: Include questions about smoking, vaping, substance use, and psychosocial stressors
This structured approach ensures you systematically exclude common diagnoses while identifying features that suggest more serious conditions requiring subspecialty evaluation and advanced testing including echocardiography, high-resolution CT, and potentially lung biopsy 1.
