Key Questions to Investigate Shortness of Breath in a 2-Year-Old Child

When evaluating shortness of breath in a 2-year-old child, focus your investigation on identifying the specific respiratory pattern, associated symptoms, and potential triggers to determine the underlying cause and severity.

Initial Assessment Questions

Respiratory Pattern and Severity

  • What is the child's current respiratory rate? (Normal for 2-year-old: 20-40 breaths/minute) 1
  • When did the breathing difficulty start? Was onset sudden or gradual?
  • Is the breathing difficulty constant or intermittent?
  • Is there any color change (cyanosis or pallor) during episodes? 2
  • Are there any abnormal breathing sounds (wheezing, stridor, grunting)?
  • Is there visible chest retractions, nasal flaring, or use of accessory muscles?
  • Does the child have difficulty speaking or feeding due to breathing problems?

Associated Symptoms

  • Does the child have a cough? If yes:
    • Is it dry or productive?
    • When does it occur? (Day, night, with activity, only with colds) 2
    • How long has the cough been present?
  • Has the child had fever? If yes, how high and for how long?
  • Has there been any vomiting or choking episodes?
  • Is there nasal congestion or discharge?
  • Has the child been unusually tired or lethargic?
  • Has there been any change in the child's level of consciousness or responsiveness? 2

Triggers and Patterns

  • When does the child breathe hard? (At rest, with minimal activity, only with exertion) 2
  • Does the breathing difficulty worsen at certain times (night, early morning)?
  • Is there any relationship to feeding?
  • Does the breathing difficulty improve or worsen with position changes?
  • Has the child been exposed to any potential triggers (allergens, irritants, smoke)?

Medical History Questions

Previous Respiratory Issues

  • Has the child had previous episodes of breathing difficulty?
  • Has the child been diagnosed with asthma, bronchiolitis, or other respiratory conditions?
  • Has the child had pneumonia before? How many episodes and were any requiring hospitalization? 2
  • Has the child had any previous hospitalizations for breathing problems?

Birth and Development History

  • Was the child born prematurely?
  • Were there any breathing problems at birth or in the neonatal period?
  • Has the child met developmental milestones appropriately?

Medical History

  • Does the child have any known allergies?
  • Is the child taking any medications currently?
  • Has the child received all age-appropriate vaccinations?
  • Does the child have any congenital heart or lung conditions?

Environmental and Family History

Environmental Exposures

  • Is there smoking in the home or frequent exposure to secondhand smoke?
  • Have there been recent renovations or new furniture in the home?
  • Are there pets in the home?
  • Has there been any recent travel?
  • Has the child been exposed to anyone with respiratory infections?

Family History

  • Is there a family history of asthma, allergies, or other respiratory conditions?
  • Do siblings or other household members have current respiratory symptoms?

Sleep-Related Questions

Sleep Patterns

  • Does the child snore or have noisy breathing during sleep?
  • Have you noticed pauses in breathing during sleep?
  • Does the child wake up gasping or choking?
  • Does the child sleep restlessly or wake frequently? 2

Foreign Body Concerns

Choking Risk

  • Was there any witnessed or suspected choking episode?
  • Has the child had access to small objects or food items that could be aspirated?
  • Was there a sudden onset of symptoms without other explanation?

Red Flag Questions

Emergency Indicators

  • Has the child had any episodes of turning blue (cyanosis)?
  • Has the child been unable to drink or feed due to breathing difficulty?
  • Has there been any marked decrease in activity or responsiveness?
  • Has the child had any seizures or loss of consciousness with breathing difficulties? 2

Follow-up Questions Based on Initial Responses

If wheezing is present:

  • Does the child respond to bronchodilators (if previously prescribed)?
  • Is there a pattern to the wheezing episodes?

If stridor is present:

  • Is the stridor inspiratory, expiratory, or biphasic?
  • Is it worse when the child is agitated or calm?

If fever is present:

  • How high is the fever?
  • How long has it been present?
  • Has the child received any antipyretics?

Remember that accurate assessment of respiratory rate requires counting for a full minute when the child is calm, as inaccurate counting can lead to significant errors in clinical decision-making 1. Always prioritize assessment of airway patency, breathing effectiveness, and circulation when evaluating a child with respiratory distress 3.
