I inhaled air duster in a can

What Happened was my dad bought this at radio shack and was using it to get water out of his iPhone. So I thought cool I finally have something to clean my xbox 360 off with. The insides that is. Little did I know the dangers it has. I sprayed it in my room for about 17 seconds and then I was like wait can this cause cancer so then I began freaking out and looked online at kids who inhaled it and died. I just want to get rid of it now. The gas used in it was called Difluorethane. It was no Ozone depleting moisture free gas. I opened my window turned on the air conditioner and left the room but i did breath in the room when I was doing it and for about 15 seconds afterwards maybe longer. I'm extremely worried.
I think i did the best thing I could do. Also if you could tell me if there any such thing as oxygen in a can why not use oxygen, pressurized oxygen or if there's any mini blowers that sucks in air and pushes ut out like a reverse vacuums only small so it can fit in my xbox. Thanks and next time I will think twice before I spray death in a can.

One time exposure for that amount of time won't hurt you, just make sure it doesn't happen again!

Oxygen in a can is dangerous, it can turn the tiniest spark into an uncontrolled conflagration.
