What happens 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.
Can you dive after getting the bends?
The U.S. Navy policy is for a return to diving after 30 days for severe decompression sickness or air embolism (AGE) that completely resolves with treatment. The time period is shorter for pain only DCS.
Is the bends life threatening?
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.
What does it mean when a diver gets the bends and what does it have to do with solubility?
The Solubility as a Function of Pressure
In the case of The Bends: If a diver goes deeper and deeper into the water, more nitrogen builds up in the bloodstream and other tissues. Following Henry’s Law; as the pressure increases, the solubility of nitrogen in the diver’s bloodstream increases.
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 the bends happen in a pool?
Decompression sickness is not totally dependent on deep/long dives. Uncontrolled or even controlled successive ascents in a short period, such as those experienced during pool training, can cause microbubbles to form in the blood stream, leading to DCI.
Why are the bends painful?
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.
Can you get a mild case of the bends?
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.
Why do divers get the bends?
Decompression sickness, also called generalized barotrauma or the bends, refers to injuries caused by a rapid decrease in the pressure that surrounds you, of either air or water. It occurs most commonly in scuba or deep-sea divers, although it also can occur during high-altitude or unpressurized air travel.
