An oxygen bar is an establishment, or part of one, that sells oxygen for recreational use.
Oxygen bar guests pay about one U.S. dollar per minute to inhale a percentage of oxygen greater than the normal atmospheric content of 20.9% oxygen.
It has been claimed by alternative medicine that the human body is oxygen-deprived, and that oxygen will remove «toxins» and even cure cancer.
The medical profession warns that individuals with respiratory diseases such as asthma and emphysema should not inhale too much oxygen.[5] Higher than normal oxygen partial pressure can also indirectly cause carbon dioxide narcosis in patients with chronic obstructive pulmonary disease (COPD).
