Oxygen therapy, also known as supplemental oxygen, is the use of oxygen as a medical treatment.[1] This can include for low blood oxygen, carbon monoxide toxicity, cluster headaches, and to maintain enough oxygen while inhaled anesthetics are given.[2] Long-term oxygen is often useful in people with chronically low oxygen such as from severe COPD or cystic fibrosis.[3][1] Oxygen can be given in a number of ways including nasal cannula, face mask, and inside a hyperbaric chamber.[4][5]
