decompression sicknessdecompression sickness
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.”
- (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.
