	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 tables and dive computers have been developed that help the diver choose depth and duration of decompression stops for a particular dive profile at depth.
		Decompression time can be significantly shortened by breathing nitrox (or pure oxygen if in very shallow water), during the decompression phase of the dive.

	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.

	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 pressure in the decompression chambers is then equalised to the pressure in the bell and the divers transfer between the two.
		Decompression tables are designed on the assumption that the surface of the water is at or near sea level.

	Effects of Increased Dissolved Nitrogen From Scuba Diving: Decompression Sickness
		Decompression sickness (DCS) is not due to the pressure of nitrogen at depth per se, but instead to the formation of bubbles as dissolved nitrogen comes out of the tissues with ascent.
		Decompression sickness was appreciated as early as the mid-19th century, among bridge-building caisson workers.
		Decompression causes excess nitrogen to leave tissues and enter the blood stream, from where it travels to the lungs and is exhaled.

		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.
		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.

	Decompression sickness
		Decompression sickness, also called the bends, is caused by nitrogen bubbles forming in the bloodstream and tissues of the body.
		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.
		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.

	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.
		Decompression involves stopping and waiting for a period of time at different depths as one rises to the surface.

	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.

	Cause of Decompression Sickness - Undersea and Hyperbaric Medicine - Foreign Medical Schools
		Decompression sickness is the product of human curiosity, reflecting the marriage of exploration and technology.
		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).
		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.

	Dive Physiology - Decompression Sickness
		In recreational diving, decompression sickness may have symptoms that are subtle.
		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.

	Howstuffworks "What causes "the bends"?"
		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).
		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.

		decompression sickness, physiological disorder caused by a rapid decrease in atmospheric pressure, resulting in the release of nitrogen bubbles into the body tissues.
		It is also known as caisson disease, altitude sickness, and the bends.
		Those who suffer symptoms of decompression sickness at high altitudes (commonly called aeroembolism) experience relief on returning to an atmospheric pressure normal to them; this and oxygen inhalation will usually effect recovery.

	THE MERCK MANUAL, Sec. 20, Ch. 285, Injury During Diving Or Work In Compressed Air
		A disorder resulting from obstruction of cerebral blood vessels by gas emboli originating in the lungs, usually due to overinflation of the lungs by expanding pulmonary gas during reduction of surrounding pressure (eg, during ascent from depth in diving) and generally characterized by early loss of consciousness and/or other CNS manifestations (see Table 285-1).
		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.
		Decompression sickness seldom develops when dives are kept within appropriate no-stop limits or when decompression tables are followed.

	Spinal Cord Decompression Sickness (Site not responding. Last check: 2007-10-07)
		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.
		Sport divers generally use compressed air as the breathing mixture, and in their case, the inert gas that may be liberated during decompression is nitrogen.
		Scuba diving is associated with risk of severe decompression sickness with primarily spinal cord involvement (DCS type II).

	Scottish Diving Medicine - Decompression Illness
		Decompression Illness (DCI) is an umbrella term for both decompression sickness (DCS) and Cerebral Arterial Gas Embolism (CAGE).
		It should be noted that the presence of inert gas bubbles does not in itself lead to problems - what is important is the eventual size of these bubbles, their location, and the ability (or inability) of the body to rid itself of them before they cause damage.
		The risk of developing decompression sickness depends on many factors, most of which are not yet clearly understood.

	Decompression Sickness \| aHealthyAdvantage (Site not responding. Last check: 2007-10-07)
		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.
		Instead of being exhaled, however, the extra nitrogen safely dissolves into the tissues, where it remains until the diver begins his or her return to the surface (under some circumstances the extra nitrogen can cause nitrogen narcosis, but that condition is distinct from DCS).
		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.

	Can exercise before diving prevent decompression sickness? (Site not responding. Last check: 2007-10-07)
		Decompression sickness following diving is initiated by the formation of gas bubbles in tissue and blood.
		The most common decompression related problem in sports divers is injury of the central nervous system, the risk of which is higher with increasing number of bubbles.
		Preventive measures to reduce the risk of decompression sickness include breathing oxygen and reducing decompression speed.

	Talk:Decompression sickness - Wikipedia, the free encyclopedia
		The conditions themselves (decompresion sickness) are the same.
		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.

	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 with neurologic or cardiopulmonary symptoms is often referred to as Type II DCS.
		The US Navy Decompression Tables were compiled after studying the effect of decompression on young, fit men and have been found in some cases not to apply to the average recreational diver.

		If you suspect decompression sickness, stop the dive, initiate first aid, and summon assistance from a specialist in divers'; medicine.
		The symptoms of decompression sickness vary because the nitrogen bubbles can form in different parts of the body.
		To minimise the risk of bubbles forming and divers developing decompression sickness, various tables have been drawn up that show the relationship between a given depth of water and the time a diver can stay down.

	Flying After Diving
		Since we are constantly exposed to a pressure of one atmosphere at sea level, the tissues of the body are in equilibrium with the nitrogen partial pressure in the air.
		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.

	Altitude Decompression Sickness: Tiny Bubbles, Big Troubles
		Decompression sickness (DCS) describes a condition characterized by a variety of symptoms resulting from exposure to low barometric pressures that cause inert gases (mainly nitrogen), normally dissolved in body fluids and tissues, to come out of physical solution and form bubbles.
		When the body is expose to decrease barometric pressures (as in flying an unpressurized aircraft to altitude or during a rapid decompression), the nitrogen dissolved in the body comes out solution.
		An individual exposed to a rapid decompression (high rate of ascent) about 18,000 feet has a grater risk of altitude DCS than being exposed to the same altitude but as a lower rate of ascent.

		ABSTRACT This study, conducted at Princess Haya Hussein Hospital Hyperbaric Department, examined 23 cases (22 males, 1 female), diagnosed with decompression sickness (types I and II) and treated with hyperbaric therapy.
		The results showed 61% of dive accidents were decompression sickness type II; 26% of treated patients had residual symptoms after the first session of recompression treatment and 74% made a full recovery.
		The study concludes that decompression sickness type II is the most common type, found mainly in sports divers.
