Which emergency condition can result from a diving accident?

A diving accident can lead to arterial gas embolism due to rapid ascent after deep diving. During a deep dive, a diver breathes in high pressure of gases, primarily nitrogen, which dissolves into the body’s tissues and bloodstream. If a diver ascends too quickly, the dissolved nitrogen can form bubbles in the bloodstream, leading to an arterial gas embolism. This can obstruct blood flow and create life-threatening complications, affecting various organs.

The other conditions, while serious in their own right, are not specifically linked to the physiological changes and risks associated with diving accidents. Pneumonia is an infection that affects the lungs and is usually unrelated to diving. Heat exhaustion is typically caused by prolonged exposure to high temperatures and is not a result of diving. Hypothermia results from prolonged exposure to cold temperatures and is also not directly associated with the dynamics of diving ascents and the subsequent risks of gas embolism.
