What causes the bends in diving?
Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues. This doesn’t cause a problem when a diver is down in the water.
What increases risk of the bends?
1. Exertion. The timing and intensity of exercise (also known as workload) during a dive can substantially affect a diver’s risk of DCS. Exertion increases blood flow and its gas carrying capacity.
What gas law is responsible for the bends?
Henry’s Law
Decompression sickness, or “the bends,” is related more to Henry’s Law, which states that more gas will be dissolved in a liquid when the gas is pressurized. Because of the water pressure, body tissue absorbs nitrogen gas faster as a diver descends than when ascending to the surface.
What are the bends and how can they be prevented?
How To Prevent The Bends. To prevent decompression sickness, divers limit their ascent rate and carry out a decompression schedule as necessary, to stop the release of bubbles that cause damage to the body. “If you have access to oxygen, a mask should be applied to the diver as soon as possible.”
Why do freedivers not get the bends?
Free divers really don’t have to worry about decompression sickness (the bends) because they are not breathing compressed air underwater. They are simply taking a breath of air at the surface, descending, and returning to the surface with that same breath of air. Things just go back to normal.
Do submariners get the bends?
Submariners do not get the bends while in a pressure hull, just fyi. So to answer your question, the submarine can go as deep as you want, but the diver is limited to the depth/time under that he can go and still breathe.
How do you prevent bends?

What depth causes bends?
“This condition is quite difficult to diagnose and, untreated, can lead to permanent disability.” One diver got the bends – a painful condition caused by gas bubbles forming in the bloodstream – from diving in water less than four metres deep.
Can you get the bends in 10 feet of water?
How great is the risk? About 40 percent of the bent divers made a single dive with only one ascent. The shallowest depth for a single dive producing bends symptoms was ten feet (three meters), with the bottom time unknown. However, most of the divers made several shallow dives and sometimes multiple ascents.
