Caisson disease \Cais"son dis*ease"\ (Med.)
   A disease frequently induced by remaining for some time in an
   atmosphere of high pressure, as in caissons, diving bells,
   etc. It is characterized by neuralgic pains and paralytic
   symptoms. It is variously explained, most probably as due to
   congestion of internal organs with subsequent stasis of the
   blood.
