I have actually had the uncomfortable feeling of hyperventilation when my dad died. Not good.

I'm always amazed by the simple changes that can make huge differences in medicine today. We've still got a lot to learn!

Yet growing research suggests that inhaling straight oxygen can actually harm the brain.  For the first time, a new UCLA brain-imaging study reveals why.
