This study aims to evaluate whether placing nasogastric tubes for gastric decompression improves respiratory distress for patients with bronchiolitis who are receiving oxygen via high-flow nasal cannula.

All patients will be consented per IRB procedure. The study will be a prospective study. Study participants will be enrolled after placement on high flow nasal cannula. The respiratory therapist or study staff will use a bronchiolitis scoring tool, the Marlais Risk of Admission Score, to assess the respiratory status of patients after placement on high flow nasal cannula, and prior to placement of NG tube to establish a baseline measurement. This tool includes the following components: respiratory rate, oxygen saturation, heart rate, age, and length of illness. An NG tube will then be placed. Thirty minutes and sixty minutes after placement of the NG tube, the respiratory therapist or study team will again use this scoring tool to assess the respiratory status of the patient. After 60 minutes the study will be concluded. As subject will be requiring oxygen use, admission to an inpatient unit is required. The NG tube will be removed at the discretion of the provider or the admitting physician, who may choose to keep it in at their discretion.
