decompression sicknessIllness brought about by a sudden and substantial change in hydrostatic pressure. It is caused by a too rapid release of nitrogen that has been dissolved into the bloodstream under pressure; when the nitrogen forms bubbles it causes the bends. The condition causes breathing difficulties, joint and muscle pain, and cramps, and is experienced mostly by divers who surface too quickly. After a one-hour dive at 30 m/100 ft, 40 minutes of decompression are needed, according to US Navy tables. How to thank TFD for its existence?
