Decompression sickness - Wikipedia, the free encyclopedia Decompression sickness, (DCS), diver's disease, the bends, or caisson disease is the name given to a variety of symptoms suffered by a person exposed to a reduction in the pressure surrounding their body. Decompression sickness can happen in any of the following situations: Decompression time can be significantly shortened by breathing nitrox (or pure oxygen if in very shallow water), during the decompression phase of the dive. en.wikipedia.org /wiki/Decompression_sickness   (3329 words)

Decompression Sickness: Diving and Compressed Air Injuries: Merck Manual Home Edition Decompression sickness (decompression illness, caisson disease, the bends) is a disorder in which nitrogen dissolved in the blood and tissues by high pressure forms bubbles as pressure decreases. The risk of developing decompression sickness increases with increasing pressure (that is, the depth of the dive) and with the length of time spent in a pressurized environment. The inability to eliminate decompression sickness may be because the published tables and computer programs do not completely account for the variation in risk factors among different divers or because some people fail to obey the recommendations of the tables or computer. www.merck.com /mmhe/sec24/ch295/ch295c.html   (1820 words)

Discovery Health :: Diseases & Conditions :: decompression sickness Decompression sickness takes place when sudden pressure changes in the environment cause gases that are dissolved in the blood and tissues to form bubbles of gas. Pain is the most common symptom of decompression sickness.

BBC - h2g2 - Decompression Sickness - A812747 Decompression Sickness, or the bends to use its common name, is a condition that arises in divers when the nitrogen dissolved in the tissues of the body comes out of solution, ie, it bubbles or fizzes. The only effective treatment for decompression sickness is recompressing in a decompression chamber. This mild form of decompression sickness nearly always clears up on its own and without treatment. www.bbc.co.uk /dna/h2g2/alabaster/A812747   (2448 words)

Cause of Decompression Sickness - Undersea and Hyperbaric Medicine - Foreign Medical Schools Nitrogen was thus implicated in the Grecian bend, decompression sickness as derogatorily articulated by workers constructing the piers of the Brooklyn Bridge under pressure: The bent posture assumed by afflicted individuals was reminiscent of the Grecian bend, a fashionable posture assumed by women of the era. It is ironic, therefore, that the first well-documented victim of decompression sickness was a snake, described by Boyle (1670) as "furiously tortured" in an enclosed rarified atmosphere (perhaps payback for the apple). Decompression sickness is the product of human curiosity, reflecting the marriage of exploration and technology. www.eustatiantube.org /dcsbook/chp1.a.cause.a.html   (449 words)

Decompression Sickness (The Bends) Decompression sickness was discovered in the 19th century by caisson workers. Some people will develop decompression sickness on no-decompression dives, within safe limits, due to assorted states in the diver or the environment, stimulating him to absorb excessive amounts of nitrogen or obstructing its release. As soon as it is believed that the victim has decompression sickness positive pressure oxygen (100%) must be given. www.rescuediver.org /med/bends.htm   (2981 words)

Decompression Sickness, Part I (Medscape) Decompression sickness is treated with recompression in a chamber to 60 FSW or deeper, associated with hyperbaric oxygen breathing. Decompression sickness is treated with recompression in a chamber to 60 FSW or deeper associated with hyperbaric oxygen breathing. Decompression sickness with neurologic or cardiopulmonary symptoms is often referred to as Type II DCS. www.scuba-doc.com /DCSPartI.html   (4731 words)

Decompression Sickness--What is it and how can you reduce risk Decompression illness consists of two conditions, DCS is a series of symptoms that result from the presence of bubbles formed in either the tissues or blood as a result of changes in pressure on the body. Arterial gas embolism (AGE) occurs when gas bubbles enter the blood stream usually as a result of decompression damage to a lung (pulmonary embolism), where the bubbles travel in the blood to the brain and cause cerebral symptoms. Watch Your Time, leaving a little extra cushion in your dive profile or green on your computer dial is wise and safer than pushing the deco limits on every dive—especially when you’re doing multiple dives on multiple days. www.suite101.com /article.cfm/scuba_diving/79152   (438 words)

Dive Physiology - Decompression Sickness Decompression sickness symptoms can occur together or individually, and can occur anywhere in the body, and may be accompanied by a feeling of lightheadedness. Regardless of the severity of the symptoms, all cases of decompression sickness are considered to be serious. In recreational diving, decompression sickness may have symptoms that are subtle. www.iit.edu /~elkimar/design/physiology/decomp.html   (505 words)

TP 13312 - Handbook for Civil Aviation Medical Examiners The cause of decompression sickness is the formation of gas bubbles in the body and the physical law was described by Henry. It occurs in 5- 7% of cases of decompression sickness, and, in altitude cases not relieved by returning to ground level, the central nervous system is involved 35-50% of the time. By the end of WWI the possibility of decompression sickness in aviators was predicted and once high altitude balloon flights were undertaken the prediction was fulfilled. www.tc.gc.ca /CivilAviation/Cam/tp13312-2/section2/decompression.htm   (966 words)

Decompression sickness Decompression sickness, also called the bends, is caused by nitrogen bubbles forming in the bloodstream and tissues of the body. The length of this rest depends on the severity of the decompression sickness and the effects of treatment, and should be discussed with a specialist in divers' medicine. This is because the risk of developing decompression sickness is not only determined by the depth and length of the dive, but also by any safety/decompression stops. www.netdoctor.co.uk /travel/diseases/decompression_sickness.htm   (1529 words)

Decompression Sickness aHealthyAdvantage Decompression sickness (DCS) is a dangerous and occasionally lethal condition caused by nitrogen bubbles that form in the blood and other tissues of scuba divers who surface too quickly. You are here: Home > Health A to Z > Decompression Sickness On the way up, decompression occurs (in other words, the water pressure drops), and with the change in pressure, the extra nitrogen gradually diffuses out of the tissues and is delivered by the bloodstream to the lungs, which expel it from the body. www.ahealthyadvantage.com /topic/topic100586700   (1442 words)

THE MERCK MANUAL, Sec. 20, Ch. 285, Injury During Diving Or Work In Compressed Air Decompression sickness seldom develops when dives are kept within appropriate no-stop limits or when decompression tables are followed. They occur in > 50% of patients with decompression sickness and are much more common after scuba dives than after caisson work or dives with traditional suit and helmet. Patients with spinal cord injury due to decompression sickness have a much more favorable prognosis than do those with cord injury due to other causes. www.merck.com /mrkshared/mmanual/section20/chapter285/285b.jsp   (1232 words)

Howstuffworks "What causes "the bends"?" Decompression sickness, also known as the bends, is one danger of diving. If the diver decompresses properly, remains at "recreational depths" (less than 100 feet or so), and is careful about the air supply, the dangers can be largely eliminated. If the diver does rise too fast, the only cure is to enter a pressurized chamber in which the air pressure matches the pressure at depth (breathing 100-percent oxygen on the way to the chamber also helps). science.howstuffworks.com /question101.htm   (553 words)

Talk:Decompression sickness - Wikipedia, the free encyclopedia Since the treatment for DCS and embolisms are the same, it would seem redundant to have treatment listed three times (once for Decompression sickness, once for Decompression illness, once for air embolism). It may be worth putting all the treatment under Decompression illness to avoid re-work, or to have a separate article that's transcluded into all DCS/DCI/Air embolism. The conditions themselves (decompresion sickness) are the same. en.wikipedia.org /wiki/Talk:Decompression_sickness   (493 words)

Spinal Cord Decompression Sickness Decompression sickness (DCS) is a clinical syndrome caused by alterations in environmental pressure, which result in the liberation into tissue or blood of inert gas bubbles previously loaded within tissues as a soluble phase. Scuba diving is associated with risk of severe decompression sickness with primarily spinal cord involvement (DCS type II). This exhibit discuss the value of MR imaging in the detection of pathologic changes of spinal cord decompression sickness, that were previously undetectable by other neuroimaging methods. mbox.unipa.it /~radpa/l1/dcs.html   (680 words)

Scottish Diving Medicine - Decompression Illness Decompression Illness (DCI) is an umbrella term for both decompression sickness (DCS) and Cerebral Arterial Gas Embolism (CAGE). The risk of developing decompression sickness depends on many factors, most of which are not yet clearly understood. There are conflicting studies showing the existence, or lack, of a relationship between a diver's age / gender and the incidence of decompression sickness. www.sdm.scot.nhs.uk /decompression_illness   (3146 words)

Decompression Sickness Report Decompression Sickness (DCS) is a condition which is caused by the evolution of Nitrogen bubbles from blood and tissues when a person is decompressed from a higher to a lower atmospheric pressure. Regardless, of the road taken, divers will be at increased risk for decompression sickness if the rules of safe diving and traveling after diving are not followed. However, when decompressions exceed the factor of two bubble nuclei may begin to form. www.amtiusa.com /frst_ed/digpg13.htm   (333 words)

Flying After Diving There is no risk of decompression sickness from skiing on high peaks, driving over mountain passes or flying in a commercial aircraft. The incidence of decompression sickness among these divers is estimated to be about 0.004 percent. Experimental studies in animals showed that exposure to altitude after diving increases the severity and incidence of decompression sickness. www.skin-diver.com /departments/scubamed/FlyingAfterDiving.asp?theID=332   (923 words)

Conservative Dive Profiles and Decompression Sickness It is clear, therefore, that complaints of symptoms consistent with decompression sickness should be viewed seriously, particularly when first-time divers are involved (despite the fact that some novices are clearly preoccupied with the threat of decompression sickness). More specifically, signs and symptoms consistent with the diagnosis of decompression sickness should not be minimized or ignored simply because a dive or series of dives was comparatively conservative. Every year, recompression facilities receive divers afflicted with symptoms of decompression sickness, despite the fact that extremely conservative dive profiles were observed. www.eustatiantube.org /dcsbook/chp3.e.profiles.b.html   (855 words)

Decompression Sickness Decompression sickness (DCS) occurs when the body is subjected to a sudden reduction in surrounding pressure. The only risk factor for decompression sickness is a sudden reduction in pressure.

Decompression Sickness The concern with flying after diving is decompression sickness (DCS or the "bends"), which is the formation of gas bubbles in the tissue when the diver ascends too fast from depth. Dives requiring decompression stops: The surface interval should be at least 24 and, if possible, 48 hours before flying. www.hhp.ufl.edu /keepingfit/ARTICLE/dcs.HTM   (200 words)

Decompression Sickness You have decompression sickness caused by the formation of bubbles in the blood and elsewhere. The question is: "How deep do you have to dive in order to be subjected to bubbles causing decompression sickness?" J.S. Haldane in the early 1900's discovered if a person halved their pressure they could have bubble formation. For years this author dove with the mistaken notion that if we surfaced properly (then 25'/minute, now 60'/minute), and did not exceed the time allowed on the USN Decompression Table at various depths in order to avoid a ceiling, we would avoid having those horrible nitrogen bubbles form creating decompression sickness. www.deep-six.com /page78.htm   (4674 words)

Altitude Exposure After Diving Nevertheless, it is also known that decompression sickness is a "probabilistic" event. After Recompression, Status Post DCS: The highest risk of all is after recompression Hyperbaric Oxygen Therapy for even a mild case of decompression sickness. The state of the body that describes the probability of dissolved nitrogen coming out of solution to produce DCS is referred to as "decompression stress." It is thought by many researchers that disordering of the microcirculation can occur in some situations such as multiple or deep dives, thus interfering with predictable off-gassing of nitrogen. faculty.washington.edu /ekay/altitude.html   (745 words)

Scuba Adventurer decompression sickness article If a diver is suspected of decompression sickness, and you are not diving with professional supervision, such as on a charter boat, you should know the steps to take. While there’s always some minimal possibility that decompression sickness (DCS) will occur, even when you do everything right, you should be aware that the primary reason divers suffer DCS is from diver error. These include misuse of, of failure to use dive tables or dive computer, exceeding proper ascent rates, omitting emergency decompression stops, running out of air (which can lead to exceeding proper ascent rates and omitting emergency decompression/safety stops), ignoring factors that predispose divers to DCS, and failure to follow conservative diving practices. www.scubaadventurer.com /article_decompression_sickness.htm   (616 words)
