Oxygen therapy refers to breathing a high level of oxygen for a short time to correct a lack of oxygen in the tissues of the body. To raise the level of oxygen in damaged tissues, pure (100%) oxygen can be breathed with a tight fitting mask, but because oxygen is poorly soluble in blood it is also necessary to use a higher pressure. Individuals receiving oxygen therapy therefore need to sit in a pressure chamber, known as a barochamber.
These are built of steel and accommodate between one and 4 people. Barochambers are pressurised up to twice normal atmospheric pressure. The pressure inside is increased by using compressed air, and oxygen is provided by a built-in breathing system. This is exactly the same technology used in pressurised commercial aircraft. Anyone can access the therapy – a referral from a GP or consultant is not required, and the oxygen therapy is administered by trained operators.
Patients find that oxygen therapy assists with the alleviation of a number of symptoms, particularly fatigue, incontinence, pain and muscle control. Many have been using it successfully for over 25 years. Oxygen therapy has also been shown to reduce deterioration with long-term use.
Discussion with a GP about suitability for treatment is advised but not required.
