Your question: What are the bends in pearl diving?

What do the bends feel like?

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. Other associated signs and symptoms can include dizziness, confusion, vomiting, ringing in the ears, head or neck pain, and loss of consciousness.

At what depth can you get the bends?

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.

What happens 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.

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.

Can the bends go away on their own?

In some cases, symptoms may remain mild or even go away by themselves. Often, however, they strengthen in severity until you must seek medical attention, and they may have longer-term repercussions.

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.

How do dolphins avoid the bends?

Dolphins conserve oxygen and prevent dive-related problems by consciously decreasing their heart rates before diving. … This allows them to conserve oxygen and adjust their body to the changing pressure as they dive, therefore avoiding issues such as ”the bends”.

How do sperm whales not get the bends?

Under pressure

“The only stressor known to cause this kind of bone damage is the bends,” he says. This implies that the whales stave off the effects of the bends not through some in-built physiological mechanism, but rather by carefully managing their diving patterns much as scuba-divers do.

How 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.

How deep can you dive and not get the bends?

The deeper and longer your dive the more chance you need decompression stops. Shallow dives of 6-10 metres (20-30 feet) you can spend over 200 minutes without a decompression stop. Dives to over 30 metres (100 feet) limit your dive time to around 20 minutes before a decompression stop is required.
