There are also devices on sale that offer "oxygen massage" and "oxygen detoxification" with claims of removing body toxins and reducing body fat. The American Lung Association has stated "there is no evidence that oxygen at the low flow levels used in bars can be dangerous to a normal persons health", but the U.S. Center for Drug Evaluation and Research cautions that people with heart or lung disease need their supplementary oxygen carefully regulated and should not use oxygen bars.Victorian society had a fascination for the rapidly expanding field of science. In "Dr. Oxs Experiment", a short story written by Jules Verne in 1872, the eponymous doctor uses electrolysis of water to separate oxygen and hydrogen. He then pumps the pure oxygen throughout the town of Quiquendone, causing the normally tranquil inhabitants and their animals to become aggressive and plants to grow rapidly. An explosion of the hydrogen and oxygen in Dr Oxs factory brings his experiment to an end. Verne summarised his story by explaining that the effects of oxygen described in the tale were his own invention (they are not in any way supported by empirical evidence). There is also a brief episode of oxygen intoxication in his "From the Earth to the Moon". See also

Hypobaric setting
In low-pressure environments oxygen toxicity may be avoided since the toxicity is caused by high partial pressure of oxygen, not merely by high oxygen fraction. This is illustrated by modern pure oxygen use in spacesuits, which must operate at low pressure (also historically, very high percentage oxygen and lower than normal atmospheric pressure was used in early spacecraft, for example, the Gemini and Apollo spacecraft). In such applications as extra-vehicular activity, high-fraction oxygen is non-toxic, even at breathing mixture fractions approaching 100%, because the oxygen partial pressure is not allowed to chronically exceed 0.3 bar (4.4 psi). Management
During hyperbaric oxygen therapy, the patient will usually breathe 100% oxygen from a mask while inside a hyperbaric chamber pressurised with air to about 2.8 bar (280 kPa). Seizures during the therapy are managed by removing the mask from the patient, thereby dropping the partial pressure of oxygen inspired below 0.6 bar (60 kPa).A seizure underwater requires that the diver be brought to the surface as soon as practicable. Although for many years the recommendation has been not to raise the diver during the seizure itself, owing to the danger of arterial gas embolism (AGE), there is some evidence that the glottis does not fully obstruct the airway.
