When underwater divers breathe compressed air that contains nitrogen gas at the same pressure as the surrounding water.
Decompression sickness one. Decompression Sickness DCS is a condition in which rapid changes of pressure in an environment causes gases to form bubbles of gas mainly nitrogen. The amount of gas dissolved is proportional toand increases withthe total depth and time a diver is below the surface. Some relate to the gross expansion of gas in.
The term decompression illness DCI was coined to encompass both DCS and the related condition known as arterial gas embolism AGE the latter arising from barotrauma of the lungs that introduces gas into the systemic bloodstream. The bends is a colloquial or informal term that people often use when referring to DCS. Decompression sickness can cause long-term damage.
3152017 Decompression sickness DCS which is caused by inert gas bubbles in tissues is an injury of concern for scuba divers compressed air workers astronauts and aviators. It can be caused by an acute decompression from ground level to altitude or more commonly by decompression from a dive or hyperbaric chamber exposure back to ambient pressure. One of the hazards associated with underwater diving is decompression sickness DCS caused by uncontrolled release of gas from tissues during or after surfacing Diving is a popular recreational pastime as well as an activity with numerous practical applications in the scientific commercial military and exploration realms.
I have been working as a scuba instructor for many years and experienced very few cases of decompression sickness I recall three in total. 5172018 Why is decompression sickness called the bends.

The label comes from the associated joint pain which is one of the many symptoms of this dangerous and potentially lethal condition.
As the diver ascends the excess dissolved gas must be cleared through respiration. 7292020 Having had decompression sickness may place one at increased risk for future similar events.

11272019 Decompression sickness is a type of injury that occurs when theres a rapid decrease in pressure surrounding the body. Decompression sickness also called bends or caisson disease physiological effects of the formation of gas bubbles in the body because of rapid transition from a high-pressure environment to one of lower pressure.
