What can increased nitrogen accumulation during dives lead to?

Increased nitrogen accumulation during dives primarily leads to decompression sickness, commonly known as "the bends." As a diver descends, the high pressure causes nitrogen from the breathing gas to dissolve into bodily tissues. If a diver ascends too quickly, the rapid decrease in pressure can cause the dissolved nitrogen to form gas bubbles in the bloodstream and tissues. This can lead to various symptoms, including joint pain, neurological issues, and in severe cases, can be life-threatening.

Decompression sickness occurs due to the violation of safe ascent practices, highlighting the importance of controlled ascent and adherence to dive tables or computers. Vigilance in managing nitrogen exposure during dives is crucial for preventing this condition.

While drowning, explosive decompression, and underwater hysteria are significant risks in diving, they are not directly caused by accumulated nitrogen during the dive. Drowning results from various factors, including equipment failure or loss of buoyancy. Explosive decompression usually refers to rapid changes in pressure in extreme environments, such as high altitudes, rather than in recreational diving. Underwater hysteria can occur due to anxiety or panic but is not a direct result of nitrogen buildup.
