An oxygen container, also known as an oxygen TENT, is a device used to provide a high concentration of oxygen to a patient. It is typically made of a flexible material and is placed over the patient's head and shoulders. The TENT is connected to an oxygen source, such as a tank or wall outlet, and the oxygen is then delivered to the patient through the TENT. Oxygen tents are commonly used in hospitals and other medical settings to treat patients with respiratory illnesses or conditions that require supplemental oxygen.
