This, in turn, causes dissolved gases, such as nitrogen, to come out of solution and form bubbles. It occurs most commonly in scuba or deep-sea divers, although it also can occur during high-altitude or unpressurized air travel. Dive tables, such as the U.S. Navy Dive Tables, provide general guidelines as to what depths and dive times are less risky for the development of decompression sickness.
