In addition to nitrogen narcosis, what is another diving condition divers should monitor?

Decompression sickness (DCS), often referred to as "the bends," is a significant condition that divers need to monitor due to the implications it has on diver safety. This condition occurs when a diver ascends too quickly after spending time at depths under pressure. When descending, the body's tissues absorb nitrogen from the breathing gas. If a diver ascends too quickly, the nitrogen that was absorbed can form bubbles in the bloodstream, leading to various symptoms that can be mild to severe, including joint pain, dizziness, difficulty breathing, and even life-threatening conditions.

Understanding and managing dive profiles, including ascent rates and safety stops, are essential practices to prevent DCS. Divers should also be familiar with the limits of their dive tables or computers, as these devices help to monitor nitrogen absorption and ensure a safe ascent back to the surface. By being aware of decompression sickness and its prevention, divers can significantly enhance their safety while engaging in this sport.

While hypothermia, allergic reactions, and shark encounters are valid concerns in diving, they do not directly relate to the physiological risks associated with ascent and nitrogen management in the same way that decompression sickness does.
