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 ...
This second group further divides conditions caused by exposure to ambient pressures significantly different from surface atmospheric pressure, and a range of conditions caused by general environment and equipment associated with diving activities. Disorders particularly associated with diving include those caused by variations in ambient ...

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 ...
The condition generally mimics symptoms of a viral infection. Fever, malaise and chills are most commonly reported, and usually the first systemic symptoms to appear. Most individuals experience tremors and shivering [1] — the latter is worse with reduced oxygen levels in blood. [7] These symptoms tend to worsen with cold exposure or physical ...
