a certain amount will kill you, but a few little bubbles won't really do anything.
^^ not true, even small bubbles can cause air embolisms in capillary beds. Which will lead to death of the tissue supplied by those cappilaries.
Not a good idea. The bends is essentially bubbles of nitrogen gas in the blood after all.
My dad takes Cubicin every morning (through an IV PICC line). The nurses in the infusion say that little air bubble (small ones) are okay, but if there's a long line of air within the tubing then that can be fatal. It has to be a pretty long line though and not just a few small to medium air bubbles. I guess it really wouldn't be a bubble much less a huge pocket of air within the tubing (which is essentially what bubbles are but you get my point. Heh).
I would say what Dimethyltryptamine said is accurate.
But if a long line of okygen does get in, what it does is create a clot that goes to your heart and creates a stroke or heart attack.
