Rising too fast turns dissolved gas into bubbles — physics does not negotiate with your schedule.
means The process of gradually reducing pressure on something — often a diver's body — so that gases trapped inside can escape safely instead of forming dangerous bubbles.
from Built from Latin de- ('reversal, undoing') plus compression, itself from comprimere — com- ('together') and premere ('to press'). Compression entered English for the act of squeezing matter into less space; decompression is simply the deliberate undoing of that squeeze, a term that moved from physics and engineering into diving medicine once people understood that nitrogen forced into solution under pressure needs an unhurried exit, not a sudden release.
- the bends
- nitrogen bubbles form in joints and blood, not lungs
- origin
- named for 1800s caisson workers building bridge foundations
- the fix
- recompress and ascend slowly, letting gas re-dissolve gradually
- not just diving
- pilots and astronauts face it too, in reverse
