An oxygen hood, also known as an oxygen tent or oxygen canopy, is a medical device that provides supplementary oxygen to newborns and young children who need respiratory assistance. It is a clear or translucent cage that fits over the patient's head and upper torso, creating a controlled environment with improved oxygen concentration. The oxygen hood is often composed of a soft, flexible material that is comfortable for the patient, such as translucent plastic or silicone. It is intended to enclose the patient's breathing zone by covering the entire head and extending down to the shoulders or chest.
