this is from the tv show The Doctors website, about health trends of 2010 or something:
"2. Oxygen in a Can
Have you ever craved a quick shot of oxygen? New portable spray cans containing oxygen are gaining in popularity. The Doctors try them out, and Dr. Jim says, “This might be nice after a long flight. Sometimes I can feel sick and headachy. This might help out with that.”
But Dr. Travis doesn’t buy it. “I think it’s fun [to spray], but truth be told, we use oxygen in the hospital all the time with oxygen facemasks and nasal prongs when people need oxygen,” he says. “If you really need oxygen, this is not a very effective delivery form of it, and it’s probably more psychological than anything.”"
