how often do people suffer from it?
UNANSWERABLE
two scuba divers are 50 m below the surface of the water UNANSWERABLE what is this sickness about? It is a condition arising from dissolved gases coming out of solution into bubbles inside the body on depressurisation what are some of the causes this sickness? Reduction in ambient pressure and when leaving a high-pressure environment, ascending from depth, or ascending to altitude. how does this pressure react to the atmosphere? Within the atmosphere, the ambient pressure decreases as height increases. how can one calculate this pressure? In fields such as meteorology and underwater diving, it is common to see ambient pressure expressed in bar or millibar. One bar is 100 kPa or approximately ambient pressure at sea level what are some of the signs of the sickness? Joint pain accounts for about 60% to 70% of all altitude DCS cases, with the shoulder being the most common site for altitude and bounce diving, and the knees and hip joints for saturation and compressed air work.

Decompression sickness [SEP] Signs and symptoms
While bubbles can form anywhere in the body, DCS is most frequently observed in the shoulders, elbows, knees, and ankles. Joint pain ("the bends") accounts for about 60% to 70% of all altitude DCS cases, with the shoulder being the most common site for altitude and bounce diving, and the knees and hip joints for saturation and compressed air work. Neurological symptoms are present in 10% to 15% of DCS cases with headache and visual disturbances being the most common symptom. Skin manifestations are present in about 10% to 15% of cases. Pulmonary DCS ("the chokes") is very rare in divers and has been observed much less frequently in aviators since the introduction of oxygen pre-breathing protocols.
