When choosing to use oxygen therapy for a child with bronchiolitis, there is evidence that home oxygen may reduce hospitalization rate and length of stay although readmission rates and follow-up visits are increased. Also, the use of humidified, heated, high-flow nasal cannula may be a safe initial therapy to decrease work of breathing and need for intubation. However, evidence is lacking regarding the use of high-flow nasal cannula compared to standard oxygen therapy or continuous positive airway pressure. These practices may still be used in severe cases prior to intubation.
