What Researchers Did
Researchers investigated the mental and physical abilities of experienced professional divers in a hyperbaric chamber under high pressure using either air or specific gas mixtures.
What They Found
The study found that manual dexterity decreased by 2-16% and number ordering ability decreased by 4-46% compared to normal conditions. Analysis indicated that the impairment of cognitive (thinking) ability was due to the narcotic action of inert gases, while the impairment of motor (movement) ability was a direct consequence of the raised pressure itself.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This study focused on experienced professional divers, meaning the findings may not directly apply to the general population or patients undergoing hyperbaric oxygen therapy for medical conditions.
