Assessment and Management of Respiratory Distress

Introduction to Respiratory Distress Management

The American Academy of Pediatrics provides guidelines for the assessment and management of respiratory distress, including the use of pulse oximetry to detect hypoxemia not suspected on physical examination 1

Supplemental oxygen is indicated if SpO₂ falls below 90%, as recommended by the American Academy of Pediatrics 1
The American Academy of Pediatrics recommends withholding supplemental oxygen if saturation exceeds 90% 2

Repeated observation over time provides more valid assessment than a single examination, as stated by the American Academy of Pediatrics 1

Routine radiography is not supported by current evidence, as recommended by the American Academy of Pediatrics 1
Virologic testing rarely alters management decisions or outcomes, according to the American Academy of Pediatrics 1
Clinical utility of diagnostic testing, such as complete blood counts and chest radiographs, is not well supported by evidence, as stated by the American Academy of Pediatrics 1

Bronchodilators should not be used routinely, but may be considered for a carefully monitored trial with objective evaluation of response if there is audible wheezing, as recommended by the American Academy of Pediatrics 1
The American Academy of Pediatrics strongly recommends against routine use of bronchodilators in bronchiolitis, except in select cases with audible wheezing and objective evaluation of response within 15-20 minutes 1, 2
The American Academy of Pediatrics does not recommend systemic corticosteroids for routine management of bronchiolitis, as multiple high-quality studies show no significant benefit in reducing hospital admissions (pooled risk ratio 0.92; 95% CI 0.78-1.08) 2
Antibiotics should be avoided unless there is specific evidence of bacterial co-infection 1, 3, 4
Long-term macrolide antibiotics may be recommended for children with recurrent respiratory tract infections, with a treatment course of at least 6 months, as suggested by the European Respiratory Society 3

For infants with bronchiolitis, supportive care with close monitoring is the most appropriate initial management approach, as recommended by the American Academy of Pediatrics, including assessing feeding ability and hydration status, and encouraging normal feeding or smaller, more frequent feeds if necessary 1
If unable to maintain adequate oral intake, IV fluids may be necessary, according to the American Academy of Pediatrics 1

The following interventions may be indicated:

Intervention	Indication
Supplemental oxygen	SpO₂ <90%
High-flow nasal cannula	Respiratory distress worsens
Nasal suctioning	Clear secretions
Bronchodilators	Select cases with objective evaluation of response
Corticosteroids	Not recommended for routine use
Antibiotics	Specific bacterial co-infection suspected

Encourage breastfeeding to reduce the risk of bronchiolitis, and avoid exposure to tobacco smoke 1, 5
Hand hygiene before and after patient contact is essential to prevent the spread of infection 1, 5
Consider RSV prophylaxis (palivizumab) for eligible high-risk infants, including premature infants, children with congenital heart disease, and children with chronic lung disease, with a recommended dose of 15 mg/kg IM in 5 monthly doses starting before RSV season 1, 2
Ensure complete pneumococcal conjugate vaccination and annual influenza vaccination for children with recurrent respiratory tract infections, as recommended by the European Respiratory Society 3

Children with bronchitis or bronchiolitis should be considered for discharge when oxygen saturation is maintained ≥90% on room air, adequate oral intake is established, and respiratory distress has significantly improved, and monitored for risk factors for severe disease, including young age, history of prematurity, underlying cardiopulmonary disease, and immunodeficiency 2, 1
Evaluate infants with bronchiolitis and moderate to severe cough for risk factors for severe disease, including age, history of prematurity, underlying cardiopulmonary disease, and immunodeficiency 2, 1
The American Academy of Pediatrics recommends explaining the expected course of illness, advising on maintaining adequate hydration, monitoring for signs of respiratory distress, and when to seek medical attention, as well as avoiding exposure to tobacco smoke 1
