Diving Disorders
Diving disorders are medical conditions specifically arising from underwater diving. The signs and symptoms of these disorders can present in a diver during ascent, descent or even at depth.
Pronunciation
Diving: /ˈdaɪvɪŋ/ Disorders: /dɪˈsɔːrdər/
Etymology
The term 'diving' originates from the Old English 'dyfan' meaning 'to dip, duck, sink' and the term 'disorder' comes from the late 15th century, from the Old French 'desordre'.
Types of Diving Disorders
1. Decompression sickness: Also known as 'the bends', decompression sickness occurs when a diver ascends too quickly, causing nitrogen bubbles to form in the tissues and blood.
2. Barotrauma: This is physical damage to body tissues caused by a difference in pressure between an air space inside or beside the body and the surrounding fluid.
3. Nitrogen narcosis: This is a reversible alteration in consciousness producing a state similar to alcohol intoxication in divers who breathe high pressure nitrogen.
4. Oxygen toxicity: This is a condition resulting from the harmful effects of breathing molecular oxygen at elevated partial pressures.
5. Drowning: This is respiratory impairment from being in or under a liquid.
6. Hypothermia: This is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature.
