Everyone would have seen the ER atleast from the outside. And those who have never had the misfortune to visit a hospital ever, would have atleast watched it in TV. And you would have watched people breathing with masks on their faces that is supposed to supply them with more oxygen than they could get from the atmosphere. The mask is cute, but where does the oxygen come from? In olden days, people used to store them in cylinders and release it to the maskthru a valve. But this is expensive, and filling oxygen in the cylinder is a big process.
Thats why there are portable oxygen concentrator, which takes oxygen from the air around us and makes it a concentrate and feeds it to the mask so that the patient can brethe easy. This is real good stuff.
