When I was a kid, they used the exact same injectors to vaccinate us in school. That was in mid-80s. This thing was indeed virtually painless and left a funny air bubble under the skin that disappeared in an hour. As far as I was concerned it was awesome. But apparently it had some problems (infections?) and the program ended as quickly as it started.

- mbrameld 14y agoAn air embolism would only be a problem if it was in a blood vessel. Those injectors were intramuscular and the air just diffused back out through the tissue.
- loxs 14y agoI can't think of a case where this can be a problem by accident. Back when I was in the medical school (Bulgaria, Eastern Europe) we sometimes used air embolism to kill off experimental animals. I remember that the quantity of air needed is substantial. Something like 20-50 cubic centimeters needed to kill a rabbit reliably by venous (right heart) embolism. I imagine the quantity needed to kill a human is quite a lot bigger. Of course, it's not the same if you insert air in the carotid artery. I guess that quite smaller quantity there will kill a human. I speculate something in the range below 1 cm3.
