Hypercapnia is a hazard of underwater diving associated with breath-hold diving, scuba diving, particularly on rebreathers, and deep diving where it is associated with increased breathing gas density due to the high ambient pressure. [3] [4] [5]
Hypercapnia is a condition where there is ... Exposure to increased partial pressure of oxygen during diving can raise the level of oxidative stress in which ...
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 ...
Gas may find its way into a cavity in the tooth or under a filling or cap during a dive and become trapped. During ascent, this gas will exert pressure inside the tooth. Good dental hygiene, and maintenance of dental repairs to prevent or remove potential gas traps. Suit and BC expansion Loss of buoyancy control—uncontrolled ascent.
Blackout during a shallow dive differs from blackout during ascent from a deep dive in that deep water blackout is precipitated by depressurisation on ascent from depth while shallow water blackout is a consequence of hypocapnia following hyperventilation.

Narcosis results from breathing gases under elevated pressure, and may be classified by the principal gas involved. The noble gases, except helium and probably neon, [2] as well as nitrogen, oxygen and hydrogen cause a decrement in mental function, but their effect on psychomotor function (processes affecting the coordination of sensory or cognitive processes and motor activity) varies widely.

Divers decompressing in the water at the end of a dive Basic deck decompression chamber. The decompression of a diver is the reduction in ambient pressure experienced during ascent from depth. It is also the process of elimination of dissolved inert gases from the diver's body which accumulate during ascent, largely during pauses in the ascent ...
