Diving disorders are medical conditions specifically arising from underwater diving. The signs and symptoms of these may present during a dive, on surfacing, or up to several hours after a dive. The principal conditions are decompression illness (which covers decompression sickness and arterial gas embolism ), nitrogen narcosis , high pressure ...

Approximately 90 percent of patients with DCS develop symptoms within three hours of surfacing; only a small percentage become symptomatic more than 24 hours after diving. [3] Below is a summary comparison of the signs and symptoms of DCI arising from its two components: Decompression Sickness and Arterial Gas Embolism. Many signs and symptoms ...

High-pressure nervous syndrome (HPNS – also known as high-pressure neurological syndrome) is a neurological and physiological diving disorder which can result when a diver descends below about 500 feet (150 m) using a breathing gas containing helium. The effects experienced, and the severity of those effects, depend on the rate of descent ...

Narcosis results from breathing gases under elevated pressure, and may be classified by the principal gas involved. The noble gases, except helium and probably neon, [2] as well as nitrogen, oxygen and hydrogen cause a decrement in mental function, but their effect on psychomotor function (processes affecting the coordination of sensory or cognitive processes and motor activity) varies widely.
Its initial symptoms of cough and difficulty breathing are similar to near-drowning, however near-drowning does not cause viral infection-like symptoms. Furthermore it can be difficult to distinguish the condition from an acute viral infection at first; unlike viral illnesses however, salt water aspiration syndrome tends to improve within a few ...
