Oxygen therapy is the administration of oxygen as a therapeutic modality. Oxygen therapy benefits the patient by increasing the supply of oxygen to the lungs and thereby increasing the availability of oxygen to the body tissues.

Appropriate levels of oxygen are vital to support cell respiration. High blood and tissue levels of oxygen can be helpful or damaging, depending on circumstances. Hyperbaric oxygen therapy is the use of high levels of oxygen for treatment of specific diseases. High levels of oxygen given to neonates causes blindness by promoting overgrowth of new blood vessels in the eye obstructing sight. High levels of oxygen in patients with severe emphysema and high blood carbon dioxide reduces respiratory drive which can precipitate retention of more carbon dioxide.

Oxygen first aid specifically refers to the use of oxygen in a first aid setting. Oxygen may provide relief in patients with chest pain and dyspnea (shortness of breath). Care needs to be exercised in patients with chronic obstructive pulmonary disease, especially in those known to retain carbon dioxide (type II respiratory failure). For this reason, some jurisdictions require medical approval for emergency oxygen administration.
