How can a diver avoid getting decompression sickness?

What percentage of divers get decompression sickness?

Skin manifestations are present in about 10% to 15% of cases. Pulmonary DCS (“the chokes”) is very rare in divers and has been observed much less frequently in aviators since the introduction of oxygen pre-breathing protocols.

Onset.

Time to onset Percentage of cases
within 24 hours 98%
within 48 hours 100%

How does diving put you at risk for decompression sickness?

Flying within 12 to 24 hours after diving (such as at the end of a vacation) exposes people to an even lower atmospheric pressure, making decompression sickness slightly more likely. Nitrogen bubbles may form in small blood vessels or in the tissues themselves.

How do you get rid of decompression sickness?

The treatment of DCS is with 100% oxygen, followed by recompression in a hyperbaric chamber. [8] In most cases, this will prevent long-term effects. However, permanent injury from DCS is possible. To prevent the excess formation of bubbles leading to decompression sickness, divers limit their ascent rate.

Why can’t divers come up fast?

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.

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.

Will decompression sickness go away?

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.

How long after diving can you get decompression sickness?

Symptoms of DCS can occur immediately after surfacing or up to 24 hours later. On average a diver with DCS will experience symptoms between 15 minutes and 12 hours following a dive.

Why do scuba divers need to worry 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. This doesn’t cause a problem when a diver is down in the water.

How long does it take for the bends to set in?

Symptoms of the Bends. The nervous and musculoskeletal system are most often affected. If divers are going to develop symptoms, they will show within 48 hours in all cases. Most have symptoms within 6 hours, while some develop them within the first hour of surfacing from a dive.

What happens if decompression sickness goes untreated?

Untreated bends cause damage!
