Would it be possible to have an communal oxygen room in the U.K.?

[JonnyBoy12]

We all know that in Japan they have got oxygen bars but would it be possible to have a whole room filled with pure oxygen? That would save the need to bottle it all up and lots of people could fill the room at once. It could be combined with either a steam room or a swimming room and then you could do 2 things at once.

The only real problem I can see is that when people entered and left the room they would let normal air in and the pure oxygen out. This could be stopped by having the only entrance as a U-bend like in a kitchen sink. I would like this oxygen room to be built in the West Midlands area.

Thanks in advance for your replies on this rather unusual question.

The NHS already supply so called oxygen rooms at home for people who have severe respiratory problems. I knew a neighbour who had several oxygen bottles
delivered every week . They were stored in an adjacent room and the oxygen was fed into the room he lived in. That went on for years no wonder the NHS costs a fortune.

Ever heard of anti-oxidants ? People seem to want to swallow these as treatments. This is because oxygen is actually carcinogenic, and anti-oxidants in the diet may, if you believe what some folk say, help you resist cancer.
