What does the bends do to you?
The bends can affect almost any area of the body or any organ, including the lungs, heart, brain, joints, and skin. The most common signs and symptoms of the bends include joint pains, fatigue, low back pain, paralysis or numbness of the legs, and weakness or numbness in the arms.
Can you survive the bends?
Prognosis or outlook of people who develop the bends varies with the following factors: Prognosis is good with hyperbaric oxygen treatment. Delay to hyperbaric oxygen treatment: Although reports show that divers can do well after days of symptoms, delay in definitive treatment may cause damage that is irreversible.
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.
Why do whales not get the bends?
Under less pressure at shallower depths, the nitrogen bubbles expand in the bloodstream and tissue, causing pain and damage. … This mechanism would protect cetaceans from taking up excessive amounts of nitrogen and thus minimize risk of the bends, says lead author Daniel García-Parraga of the Fundacion Oceanografic.
What does the Benz mean when 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.
Are the bends fatal?
Decompression sickness (DCS), known as ‘the bends’ because of the associated joint pain, is a potentially deadly condition caused by bubbles of nitrogen gas forming in the blood and tissues. It’s most common among divers using scuba tanks, but can affect free-divers and people at high altitude.
Can you get the bends in a pool?
The answer would be; No, you won’t get “bent” from the pool sessions. However, if you fail to ascend slowly, even from a 15′ pool, you could experience problems other than Decompression Sickness (DCS / The Bends).
Can you get the bends from flying?
Even if you are flying a pressurized aircraft, altitude DCS can occur as a result of sudden loss of cabin pressure (inflight rapid decompression).
