RESUMEN
The use of high-flow nasal cannula and noninvasive ventilation has become increasingly common in emergency medicine as a first-line treatment of pediatric patients with respiratory distress secondary to asthma and bronchiolitis. When implemented in clinical practice, close monitoring of vital signs and ventilation parameters is warranted to identify possible signs of respiratory failure. This issue provides evidence-based recommendations for the appropriate use of noninvasive ventilation modalities in pediatric patients including high-flow nasal cannula, continuous positive airway pressure, and bilevel positive airway pressure in the setting of acute respiratory distress. Contraindications and complications associated with these modalities are also discussed.
