eli5 Why are air embolisms so deadly? Like, what about an air bubble can’t your body fix pretty easily?

I would have thought that an air bubble gets popped and we move on. That the gas eventually dissolves and gets passed somehow.

So, what’s going on? Why does the heart stop so violently? It acts like there was an implosion on the inside…

I don’t have an awesome explanation, but seeing what happens to an aquarium filter or water pump when it takes air instead of water is a great illustration. I think it has to do with the pressure of water vs air. Those muscles are flexing for your entire life accounting for the pressure of liquid. A lightweight gas makes it seize and almost crush itself. I’m sure there’s a much more scientific explanation.
