 This will be a prospective, randomized controlled single-blinded study of patients 3-18 months of age presenting to the Childrens Hospital Colorado ED during bronchiolitis season, diagnosed with mild to moderate bronchiolitis and persistent hypoxia and started on the Childrens Hospital Colorado Home Oxygen pathway see attached clinical care guideline. Investigators aim to enroll 220 patients. Patients will be identified by research assistants in the ED, based on physician diagnosis of bronchiolitis, with hypoxia requiring 0.5L oxygen by NC. A research assistant will approach the family and go through the informed consent process. If consent is obtained, the patient will then be randomized to one of the two study arms via a computer generated randomization table. In order to arrange for respiratory therapy, the research assistants will not be blinded. There will be an age block randomization scheme, and therefore patients aged 3-12 months will be randomized separately from patients 12.1-18 months to ensure equal distribution of age ranges in each arm.
