What causes the bends in divers?

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.

Can you die from the bends?

Decompression sickness is caused by surfacing too quickly after a deep dive. The condition can cause rashes, joint pain, headaches, and paralysis. Death only occurs in extreme cases. It can take hours or even days after a dive before sufferers become aware that they have decompression sickness.

What happens when you get the bends?

The bends, also known as decompression sickness (DCS) or Caisson disease, occurs in scuba divers or high altitude or aerospace events when dissolved gases (mainly nitrogen) come out of solution in bubbles and can affect just about any body area including joints, lung, heart, skin and brain.

What is the bends and how is it caused?

The Bends is an illness that arises from the rapid release of nitrogen gas from the bloodstream and is caused by bubbles forming in the blood and other tissues when a diver ascends to the surface of the ocean too rapidly. It is also referred to as Caisson sickness, decompression sickness (DCS), and Divers’ Disease.

Beating 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.

Can the bends be cured?

The optimal treatment is the use of a hyperbaric oxygen chamber, which is a high-pressure chamber in which the patient receives 100% oxygen. This treatment reverses the pressure changes that allowed gas bubbles to form in the blood stream.

Can you fart while diving?

Farting is possible while scuba diving but not advisable because: … An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness. The acoustic wave of the underwater fart explosion can disorient your fellow divers.

At what depth do the bends occur?

The Bends/DCS in very simple terms

Anyone who dives deeper than 10 metres (30ft.) while breathing air from a scuba tank is affecting the balance of gases inside the tissues of their body. The deeper you dive, the greater the effect.

Why are bubbles bad for divers?

When a diver descends in the water the hydrostatic pressure, and therefore the ambient pressure, rises. … If the pressure reduction is sufficient, excess gas may form bubbles, which may lead to decompression sickness, a possibly debilitating or life-threatening condition.

How do you avoid the bends?

How to Prevent the Bends?

  1. Dive within your physical limits.
  2. Take a safety stop after every 5 meters for 3 minutes to allow the nitrogen to leave your bloodstream.
  3. Avoid strenuous activity.
  4. Avoid a rapid ascent. …
  5. Avoid exercise 12 hours before a dive.
  6. Don’t fly immediately after a dive.
  7. Breathe normally during a dive.

Do free divers get the bends?

Free divers really don’t have to worry about decompression sickness (the bends) because they are not breathing compressed air underwater. … When a scuba diver breathes compressed air underwater, he or she is actually breathing in many more particles of air than they are at the surface.

What happens if you fly after diving?

Flying after diving is dangerous because it can trigger DCS, a condition that is expensive to treat and can be fatal. DCS (Decompression Sickness / The Bends) is the most-common, but easily avoidable, scuba diving injury. As already mentioned on this page, divers increase the level of nitrogen in their blood system.

How deep can you dive without decompression?

The need to do decompression stops increases with depth. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres (130 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.

Can you survive 47 meters underwater?

You can you survive 47 metres underwater but to do so you need to have the necessary training and experience as a scuba diver. To survive a deep dive to 47 metres down you must follow decompression stop limits or carry out decompression stops on your ascent to avoid getting decompression sickness.

What happens if you swim straight up in the ocean?

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.

How much pressure can a human take underwater?

Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean’s pressure can indeed crush you.
