what are some of the materials that one needs to use in such kind of diving?
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. how often do people suffer from it? UNANSWERABLE where does this sickness mostly arise from? DCS most commonly refers to problems arising from underwater diving decompression, but may be experienced in other depressurisation events such as emerging from a caisson, flying in an unpressurised aircraft at high altitude, and extravehicular activity from spacecraft. are there any limitations for breathing in such kind of diving? Yes, Breath-hold diving by an air-breathing animal is limited to the physiological capacity to perform the dive on the oxygen available until it returns to a source of fresh breathing gas, usually the air at the surface

Underwater diving [SEP] Breath-hold limitations
Breath-hold diving by an air-breathing animal is limited to the physiological capacity to perform the dive on the oxygen available until it returns to a source of fresh breathing gas, usually the air at the surface. As this internal oxygen supply reduces, the animal experiences an increasing urge to breathe caused by buildup of carbon dioxide and lactate in the blood, followed by loss of consciousness due to central nervous system hypoxia. If this occurs underwater, it will drown. Blackouts in freediving can occur when the breath is held long enough for metabolic activity to reduce the oxygen partial pressure sufficiently to cause loss of consciousness.
