caisson disease

 [ka´son]

de·com·pres·sion sick·ness

a symptom complex caused by the escape from solution in the body fluids of nitrogen bubbles absorbed originally at high atmospheric pressure, as a result of abrupt reduction in atmospheric pressure (either rapid ascent to high altitude or return from a compressed-air environment); it is characterized by headache; pain in the arms, legs, joints, and epigastrium; itching of the skin; vertigo; dyspnea; coughing; choking; vomiting; weakness (and sometimes) paralysis; and severe peripheral circulatory collapse. Bone infarcts can occur from bubbles in nutrient vessels leading to long-term consequences.

A symptom complex caused by the escape from solution in the body fluids of nitrogen bubbles absorbed originally at high atmospheric pressure, as a result of abrupt reduction in atmospheric pressure (either rapid ascent to high altitude or return from a compressed-air environment); it is characterized by headache; pain in the arms, legs, joints, and epigastrium; itching of the skin; vertigo; dyspnea; coughing; choking; vomiting; weakness; possible paralysis; and severe peripheral circulatory collapse.

caisson disease

A disorder affecting divers who return to the surface too rapidly after being under high presure. Nitrogen in solution in the blood and tissues is released as bubbles which block small arteries and cause pains in the joints (the ‘bends’), severe cramps, paralysis and even death.
