What is the bends in diving?

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.

What happens when you get the bends from diving?

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 bends and anoxia?

bends means due to increase in pressure of nitrogen and then sudden decrease in pressure causes the disease but anoxia is a respiratory disease caused due to decrease in pressure (not due to nitrogen) 2.

What happens to your body when you get the bends?

(Decompression Illness; Caisson Disease; The Bends) Decompression sickness is a disorder in which nitrogen dissolved in the blood and tissues by high pressure forms bubbles as pressure decreases. Symptoms can include fatigue and pain in muscles and joints.

At what depth do you have to decompress?

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.

Will the bends go away on its own?

However, denial simply delays assitance as the diver hopes the symptoms will subside 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.

How fast do you have to ascend to get the bends?

Ascend no faster than 30 feet per minute — one foot every two seconds. The usual rate was 60 feet per minute until the U.S. Navy adopted the 30-foot-per-minute rate in 1996 and training agencies followed suit.

How deep can you dive and not get the bends?

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. In the event of an emergency, the diver cannot make an immediate ascent to the surface without risking decompression sickness.
