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 ...
The risk of deterioration at higher altitudes must be considered against the risk of deterioration if not transported. Some divers with symptoms or signs of mild decompression sickness may be evacuated by pressurised commercial airliner for further treatment after a surface interval of at least 24 hours.
Treatment depends on the specific disorder, but often includes oxygen therapy, which is standard first aid for most diving accidents, and is hardly ever contra-indicated for a person medically fit to dive, and hyperbaric therapy is the definitive treatment for decompression sickness.
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 ...
[C] Other diving conditions like pulmonary barotrauma, immersion pulmonary edema and low body temperatures can produce similar symptoms or occur alongside this syndrome; these can be distinguished through the clinical course and imaging results. [1] Treatment involves supportive care with supplemental oxygen, observation and rest. [1]

A basic knowledge understanding of the causes, symptoms and first aid treatment of diving related disorders is part of the basic training for most recreational and professional divers, both to help the diver avoid the disorders, and to allow appropriate action in case of an incident resulting in injury.
