What is it?

Hyperbaric oxygen therapy is a form of treatment in which oxygen is administered under increased pressure in a specially designed chamber.  

What does it do?

Hyperbaric oxygen increases the oxygen content in the blood and in different body tissues. It is an accepted therapy for some medical conditions, including burns, decompression sickness, severe infections, radiation-induced tissue injury, and carbon monoxide poisoning.  

Does it work?

Some people with MS report benefits from using this type of treatment.
There have been a number of rigorous clinical trials examining the effect of hyperbaric oxygen in MS. Independent reviews of these studies indicate that it is not an effective treatment for MS.
 

Should I take it?

Based on these studies the NICE Guidelines for MS, which set standards for treatment in the NHS, recommends that hyperbaric oxygen is not used.
