Best answer: Why is it called the bends in diving?

How did the bends get its name?

At the end of their working days, these poor workers were pulled up and returned to atmospheric pressure without any form of decompression. As a result of this, they often got decompression sickness and their joints were ‘bent’ out of shape.

What does it mean when a diver gets the bends?

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.

How does the bends cause death?

If you’ve scuba dived before, then you’ve definitely heard about decompression sickness or “the bends.” When divers ascend too quickly from deep waters, dissolved nitrogen in the blood forms bubbles which can cause excruciating pain in the muscles, paralysis, and in some cases even death.

Why do seals not get the bends?

Because the seal’s lung is collapsed, the bloodstream has only as much nitrogen as can stay dissolved at sea level air pressure. No additional nitrogen can enter. The deep-diving mammals can race back to the surface as fast as they want.

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 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.

How deep can you dive without getting the bends?

There’s a bit of physics and physiology involved in a full explanation, but the short answer is: 40 metres/130 feet is the deepest you can dive without having to perform decompression stops on your way back to the surface.

What happens if you come up from diving too fast?

If a diver ascends too quickly, the nitrogen gas in his body will expand at such a rate that he is unable to eliminate it efficiently, and the nitrogen will form small bubbles in his tissues. This is known as decompression sickness, and can be very painful, lead to tissue death, and even be life threatening.

What do the bends feel like?

Sometimes it can feel like a dull ache, but rarely a sharp pain. Moving the joint aggravates the pain but the pain may be reduced by bending the joint to find a more comfortable position.

Can you fly after hyperbaric chamber?


IT IS IMPORTANT:  What is a surfers diet?

Any patients treated for Decompression illness/sickness and or Arterial Gas Embolism may not fly or travel to elevated altitudes for 72 hours after their hyperbaric treatment.

Why don t scuba divers lungs collapse as they descend?

If divers descend without scuba gear, the amount of gas contained in their body cavities is constant and the volume of these cavities decreases as the surrounding water pressure becomes greater. However, … If they don’t, the pressure of the air in their lungs will cause their lungs to expand.
