🌊 What causes scuba diving bends or decompression illness ( dci )?

  • What are the Scuba Diving Bends or Decompression Illness (DCI)? "The bends" is the illness that results from nitrogen bubbles being formed in your blood stream and/or tissues. It is caused by decreasing pressure too quickly after a period of increased pressure (such as ascending too quickly after a dive).

🌊 What is decompression illness?

It is any illness that is related to a release of pressure from the body such as barotrauma .. baro (pressure) trauma (injury). It includes decompression sickness, but it is not limited to decompression sickness. It is also not limited to diving even though that is what is mostly thought of when discussing decompression illness or DCI.

🌊 What is decompression sickness or the bends?

Decompression sickness the bends is a painful and potentially fatal malady an environment of high pressure to one of lower pressure.You may also want to see the answer in the question "What does decompression mean in diving?"

🌊 Why is decompression sickness called the bends?

Decompression sickness (DCS), known as 'the bends' because of the associated joint pain, is a potentially deadly condition caused by bubbles of nitrogen gas forming in the blood and tissues. It's most common among divers using scuba tanks, but can affect free-divers and people at high altitude.

🌊 Why are the bends called decompression sickness?

  • The bends are also called ‘Decompression Sickness’ and occur because of the release of gases in the body Photo: iStock. The bends are the process of dissolved gases (mainly nitrogen) that come out of solution in bubbles because of decompression in scuba divers or high altitude or aerospace events.

What is decompression scuba diving?

  • Decompression diving is when a diver is required to make one or more stops during their ascent to give their body time to safely release the nitrogen (or other gas, such as helium) that dissolved into their tissues during the dive. The pressure you’re under as you descend through water causes nitrogen to dissolve into your body tissues.

What causes decompression for divers?

  • Many risk factors are still not fully understood, but there are a few basic factors that doctors agree increase the chance of developing Decompression Sickness: Body Fat: The theory is that nitrogen absorbs more easily into fat, so an overweight diver is at a higher risk of decompression sickness. Exercise: Interestingly, exercise has both a positive and negative effect… Gender: Theoretically women should have a higher risk of Decompression Sickness because women typically have a higher body fat percentage… More items...

What are the bends scuba 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 causes the bends when diving?

When you are diving the nitrogen in an air supply dissolves into the blood and tissues due to the high pressure. When you start to come up the pressure decreases and the nitrogen comes out or "undissolves" (like fizz in a bottle of pop) and forms bubbles in your blood vessels and tissues. This stops the blood from flowing and forms bubbles, which expand the vessels, causing a painful condition known as "the bends". Bends can also happen if divers fly immediately after diving. The pressure in airplanes is even less than that at sea level.

What does decompression mean in diving?

There are 2 possible answers. One is a simple answer to what is decompression in diving. The answer to that is simply ascending back to the surface. Any time pressure is reduced (i.e swimming shallower), the diver is decompressing. So many divers will say that all dives are decompression dives since that is an accurate description. The other possible answer is what is decompression sickness or illness. This occurs when a diver has not adequately decompressed back to the surface. In recreational diving, actual decompression stops are not required even though a "safety" stop or stops are always recommended. The purpose of the stops is to allow some of the inert gas absorbed during the dive from breathing (which is nitrogen for air or oxygen enriched air mixtures) to be released from the body prior to surfacing so the extra nitrogen does not result in "too many" bubbles. Bubbles can occur since air is comprised of roughly 79% nitrogen and 21% oxygen. Nitrogen is an inert gas since it does nothing other than just sitting there (as compared to oxygen that is metabolized and used) ... so nitrogen can build up during a dive due to the pressure on the body from being underwater. Bubbles result in tissues after almost every dive, but the body can handle them nicely, so it is excessive or too many bubbles that become a problem. The same answer applies to dives that are planned decompression stop dives that technical or commercial divers do. These dives will require stops at multiple depths to reach the surface again often using multiple different decompression gases during the different stops to accelerate the decompression times. The longer the dive, the longer the required decompression due to greater absorption of inert gas. But if adequate decompression is not done, then bubbles will form in body tissues which will result in decompression sickness commonly known as the bends ... which requires treatment in a recompression chamber ... to recompress the diver and make the bubbles smaller so they can be reabsorbed by the diver during the treatment. See the links below for some other articles on decompression and diving.

What does no decompression diving mean?

  • A "no-decompression", or "no-stop" dive is a dive that needs no decompression stops during the ascent according to the chosen algorithm or tables, and relies on a controlled ascent rate for the elimination of excess inert gases. In effect, the diver is doing continuous decompression during the ascent.

Why do divers do decompression stops?

Why is it necessary to mark a decompression stop? In scuba diving, the diver breathes a gas that is at a pressure greater than the surface pressure. If it is air, the mixture will consist of 21% oxygen and 79% nitrogen… Decompression stops are therefore used to prevent decompression sickness.

How do you prevent decompression sickness?

There is no guarantee that you can prevent decompression sickness since everyone has an individual susceptibility to it. But there are things that can be done to lessen your chances and some are not well taught. One very big thing that can be done is to minimize your exertion both before during and after the dive. So when carrying your gear, do what you can to reduce your "work" and activity. Also, hydration is a big factor, so stay well hydrated. Of course, there are the obvious answers such as dive "conservative" by staying well within recognized time limits. Also, do safety stops. Safety stops can drastically reduce bubble formation and your risk of decompression sickness. I added 2 links that discuss this topic in more detail which include strategies to minimize decompression sickness.
