Bronchiolitis is the most common lower respiratory tract disease in infants. There is no specific treatment for it and the treatment is mainly supportive. The management of bronchiolitis is the clinical hotspot recently. Continuous positive airway pressure (CPAP) has gained more attention in clinical application as it is a safe, effective, and noninvasive method and can effectively relieve symptoms of bronchiolitis and improve prognosis.
