Is oxygen shots/bar allowed in Islam

I have Ask a question about **Smoking** but this is different from it There is a new thing raising called "Oxygen Bar". It is almost same like 'Sheesha' but it is oxygen instead of smoke. But there is difference in Oxygen shot/bar that you lost your consciousness for few minutes(not sure of it). I heard that there are few advantages of it and few disadvantages but I am not sure about that. >So can anyone tell me Is it right or wrong for our health and explain it in view of Islam? **Here is wiki about oxygen bar**
