How Much Air is Needed (to cause death)

[Bonaparte]

I know someone that committed suicide this way. It didn't take much to do the job, all he had was insulin syringes. This wasn't a friend of a friend situation either.

I would venture a guess as to where the injection takes place has in impact, if the bubble gets to the lungs first your ok, if it doesn't your toast.

You would have to shoot air into your carotid artery for it to go straight to your brain.

You would have to shoot air into your carotid artery for it to go straight to your brain.

Then I would venture a guess all of the veins we have access to from like in the surface of our arms all go to our lungs.

I would assume it would take a hell of a lot of air then. As a diver, it's favorable for air to be taken to the lungs, too much results in "the chokes" but you don't die.
