Objectives: Bronchiolitis is the most common lung infection in infants and treatment focuses on management of respiratory distress and hypoxia. High-flow warm humidified oxygen (HFWHO) is increasingly used, but has not been rigorously studied in randomised trials. This study aimed to examine whether HFWHO provided enhanced respiratory support, thereby shortening time to weaning off oxygen
