Decompression-sickness meaning

A disorder, seen especially in deep-sea divers, caused by the formation of nitrogen bubbles in the blood and tissues following a sudden drop in the surrounding pressure, as when ascending rapidly from a dive, and characterized by severe pains in the joints and chest, skin irritation, cramps, and paralysis.

A condition caused by the formation of nitrogen bubbles in the blood or other tissues as the result of a sudden lowering of atmospheric pressure, as in deep-sea divers, astronauts, and pilots ascending too quickly: it is characterized by tightness in the chest, by pains in the joints, and by convulsions and collapse in severe cases.

A disorder caused by the formation of nitrogen bubbles in the blood and tissues following a sudden drop in the surrounding pressure and characterized by joint pain, skin irritation, cramps, numbness, and, in severe cases, paralysis. It occurs especially in deep-sea divers when ascending rapidly from a dive. Decompression sickness is often called “the bends.”

A common disorder that affects deep-sea divers following a sudden drop in the surrounding pressure, as when ascending rapidly from a dive. When divers are underwater, the amounts of gases such as O2 , CO2 , and N2 in their blood increase due to the increased pressure. As they ascend to the surface and the pressure decreases, the gases in their blood expand. The extra oxygen is absorbed by the body; the extra CO2 is excreted efficiently; but nitrogen, which the body does not use, forms bubbles in the blood and tissues. These bubbles cause severe pains in the joints and chest, skin irritation, cramps, and possibly paralysis. Decompression sickness can be avoided by ascending slowly to the surface, or by spending time in a decompression chamber.

(pathology) A sometimes fatal condition resulting from the formation of nitrogen bubbles in the blood and tissues, because of too rapid decompression, seen especially in deep-sea divers ascending rapidly from a dive. It is characterized by severe pains in the joints and chest, skin irritation, cramps, nausea, and paralysis.
