What causes the bends in scuba divers?

How do you prevent bends?

The Bends Prevention

  1. Diving outside dive table recommendations.
  2. Flying within 18 hours after diving: Most experts consider it reasonably safe to fly 12 hours after the last dive if the person only dove once, dove easily within the dive tables, and no decompression stop was required. …
  3. Diving in cold water.

What happens if you get the bends?

(Decompression Illness; Caisson Disease; The Bends)

Symptoms can include fatigue and pain in muscles and joints. In the more severe type, symptoms may be similar to those of stroke or can include numbness, tingling, arm or leg weakness, unsteadiness, vertigo (spinning), difficulty breathing, and chest pain.

Why do scuba divers need to worry the bends?

If they swim to the surface quickly, the dissolves gasses inside their body will react in much the same way as those inside a carbonated drink and come to surface in bubbles. This occurrence in a human body is called decompression sickness and can cause many problems, at very worst it can be fatal to a diver.

What does 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.

Can the bends be cured?

If DCS is suspected, it is treated by hyperbaric oxygen therapy in a recompression chamber. Diagnosis is confirmed by a positive response to the treatment. If treated early, there is a significantly higher chance of successful recovery.

Will the bends go away on its 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.

Is dying from the bends painful?

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. It’s a very scary risk for deepwater human divers as well as other diving species.

Can scuba diving cause blood clots?

Blood must clot whenever we cut ourselves or damage the blood vessels in any way. The bottom line is that you should not dive while taking a blood thinner because of the increased risk of bleeding.

How fast can you ascend diving?

You should never exceed an ascent rate of 10m/minute when diving shallower than about 30m. . An ascent rate of 5-6 metres per minute is recommended in the last 10m of ascent. Complete safety stops on all dives that exceed 10m depth.

Can you get a mild case of the bends?

Decompression Sickness

DCS (also called the bends or caisson disease) results from inadequate decompression following exposure to increased pressure. In some cases, it is mild and not an immediate threat. In other cases, a serious injury occurs.

How likely are you to get the bends?

It’s caused by moving too quickly towards the surface of the water, where the pressure is lower. The symptoms, which can be deadly, fitted what I was experiencing. But as I had been at only 10ft and had come up very slowly, the diving instructors insisted it couldn’t possibly be that. There was only a 1:38,000 chance.
