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 ...
DCS is best known as a diving disorder that affects divers having breathed gas that is at a higher pressure than the surface pressure, owing to the pressure of the surrounding water. The risk of DCS increases when diving for extended periods or at greater depth, without ascending gradually and making the decompression stops needed to slowly ...
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 ...
They are also exposed to raised partial pressures of oxygen if given oxygen as first aid, which is a standard protocol for most acute diving related disorders, and when undergoing hyperbaric oxygen therapy in the case of decompression sickness or arterial gas embolism.
Dysbarism or dysbaric disorders refers to medical conditions resulting from changes in ambient pressure. [1] Various activities are associated with pressure changes. Underwater diving is the most frequently cited example, but pressure changes also affect people who work in other pressurized environments (for example, caisson workers), and ...
Furthermore, it can be difficult to distinguish the condition from an acute viral infection at first; unlike viral illnesses, salt water aspiration syndrome tends to improve within a few hours. [ 1 ] The condition shares features with decompression sickness ; a review of the dive profile and the absence of other symptoms associated with ...
Diving medicine, also called undersea and hyperbaric medicine (UHB), is the diagnosis, treatment and prevention of conditions caused by humans entering the undersea environment. It includes the effects on the body of pressure on gases, the diagnosis and treatment of conditions caused by marine hazards and how aspects of a diver's fitness to ...
Biological stress is a concept developed by Hans Selye, and can be defined as a "general pathophysiological response, where similar symptoms and signs develop in response to a variety of agents and conditions". [59] This phenomenon is also known as the general adaptation syndrome. Decompression is a stressor, and decompression stress is the ...
