Thank you, it really appreciate it. It's funny you say that though because I think if for some reason I had to leave the hospital, I would want to become a firefighter! As far as your question, being a PA is a fantastic job to have. I'm in Canada, and there still just being brought into the scene, so there's not too many of them. As far as I know, there pretty big in the States, and from what I've heard it's a great job to land. It does take lots of schooling though, so if your looking for something quicker I would recommend becoming a paramedic. There's no real reason behind that answer, just nurses have to put up with a lot of crap from people.(and clean a lot of it up too!) If you have any more questions, please don't hesitate to ask. Thanks man, it really means alot. And as far as your question, you're not technically dead until your brain shuts down, but when your brain shuts down there's no real hope for you coming back to life. Your brain needs oxygen to survive, and your heart provides it with the oxygen it needs, so when your heart stops pumping, the brain stops getting the oxygen it needs. Your brain can "store" some extra oxygen for about 10 minutes, give or take. So even though you no longer have any vitals, you will still have brain activity for a short time. So when you hear someone was "dead" and brought back to life, it will usually means they had no vital signs. I really don't mind answering any medical questions anybody may have in the future!
