Nitrogen narcosis Nitrogen narcosis is an altered state of consciousness associated with breathing air at high barometric pressures (greater than 4 atm) during underwater diving or in a hyperbaric chamber Manifests as temporary impairment of cognitive and neuromuscular performance and personality and behavior changes, similar to those of alcohol intoxication Symptoms are typically associated with …
5 Interesting Facts of Carbon dioxide toxicity Toxicity owing to elevated partial pressure of carbon dioxide associated with diving with closed or semi closed circuit rebreathing apparatus As with nitrogen narcosis, diver may exhibit confusion and decreased mental performance, which may progress to convulsions or loss of consciousness As with nitrogen narcosis, condition resolves on …
6 Interesting Facts of High pressure neurologic syndrome Condition associated with hyperexcitatory neurologic symptoms, which may develop at diving depths below 120 m Attributed to helium, which is used in breathing gases for deep diving owing to absence of narcotic effects As with nitrogen narcosis, diver may exhibit behavior changes and decreased mental performance; condition …
Oxygen toxicity Acute neurotoxicity as a result of breathing oxygen at pressure exceeding 1.6 atm during diving Threshold for oxygen toxicity is higher during resting, dry exposure in hyperbaric oxygen therapy Presentation can be similar to nitrogen narcosis, with behavior changes and disorientation; auditory and visual hallucinations are also frequently reported Unlike with nitrogen narcosis, …
