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 ...
Decompression illness – Disorders arising from ambient pressure reduction; Decompression theory – Theoretical modelling of decompression physiology; Diving disorders – Physiological disorders resulting from underwater diving; Inner ear decompression sickness – Medical condition caused by inert gas bubbles forming out of solution
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 ...
Diving and hyperbaric medicine: Symptoms: Vertigo, nystagmus, nausea, ataxia, hearing loss: Causes: Gas bubbles forming in inner ear and associated vascular system from supersaturation: Risk factors: Deep diving, long decompressions, gas switching with helium mixtures, right-to-left shunt: Diagnostic method: By symptoms, inner ear involvement ...

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 ...
