History of decompression research and development gets too high when compared to the ambient pressure. These bubbles, and products of injury caused by the bubbles, can cause damage to tissues known as "decompression sickness" or "the bends". The immediate goal of controlled decompression is to avoid development of symptoms of bubble formation in the tissues of the diver, and the long-term goal is to also avoid complications due to sub-clinical decompression injury. The symptoms of decompression sickness are known to be caused by damage resulting from the formation and growth of bubbles of inert gas within the tissues and by blockage of arterial blood supply to
Decompression equipment decompression stop. Shot line configurations: A Jonline is a short line used by scuba divers to fasten themselves to something. The original purpose was to fasten a diver to a shot line during decompression stops in current. The line is typically around 1 m (3 feet) long and equipped with a clip at each end. One clip is fastened to the diver's harness, and the other is used to fasten the line to the anchor line. In current this relieves the diver from holding on to the anchor line during the decompression stop. The jonline is named after Jon Hulbert,
