Eli5 how does decompression illness kill you?

Answer 1

At normal pressure, there is X amount of gas dissolved in your blood.

At high pressure, there is a lot more gas dissovled (because it’s under pressure).

If you return to normal pressure too fast, the gas expands too quickly, and forms big bubbles because it can’t escape fast enough.

Big bubbles in your blood is bad.
