Why can’t divers go straight up?
Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. … But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage.
What is backward diving?
In diving. The second comprises the backward dives, in which the diver stands at the edge, facing away from the water, then springs and rotates backward. The third is the reverse group, in which the diver takes off in the forward position but then reverses his spin toward the board.

Can divers go down to the Titanic?
You cannot scuba dive to the Titanic due to its depth at 12,500 feet. Air consumption: one standard tank lasts 15 minutes at 120 feet. Supply for 12,500 feet would be impossible to carry even with a team. The deepest dive on record with special equipment, training and a support team is 1,100 feet.
What is the most common injury in scuba diving?
The most common injury in divers is ear barotrauma (Box 3-03). On descent, failure to equalize pressure changes within the middle ear space creates a pressure gradient across the eardrum.
What happens if you don’t equalize when diving?
However, if a diver does not equalize early or often enough, the pressure differential can force the soft tissues together, closing the ends of the tubes. Forcing air against these soft tissues just locks them shut. No air gets to the middle ears, which do not equalize, so barotrauma results.
Why do divers shower after every dive?
“Divers shower in between dives typically just to keep themselves and their muscles warm,” he says. They usually rinse off in water that’s warmer than the pool. … Diving is such a precise and fast-twitch sport, if the diver gets a little cold and tight, it could really affect their performance.”
