An oxygen tent consists of a canopy placed over the head and shoulders, or over the entire body of a patient to provide oxygen at a higher level than normal. Some devices cover only a part of the face. Oxygen tents are sometimes confused with altitude tents as used by athletes and those looking to acclimatize to a higher altitude, but those contain a reduced oxygen content.

This form of treatment is often prescribed in conditions where people have difficulty in breathing. An oxygen tent can be used in either a hospital setting or outside a health-care facility, and can be recommended for short- or long-term therapy.

Typically the tent is made of transparent plastic material. It can envelop the patient's bed with the end sections held in place by a mattress to ensure that the tent is airtight. The enclosure often has a side opening with a zipper.
