What Researchers Did
Researchers evaluated the critical flicker fusion frequency test as a tool for assessing cognitive effects and nitrogen narcosis in hyperbaric chamber attendants working at pressure.
What They Found
Attendants showed measurable changes in critical flicker fusion frequency at working pressures, indicating mild cognitive effects consistent with nitrogen narcosis. The test was feasible as an in-chamber monitoring tool.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
The study involved a small number of attendants under controlled conditions that may not reflect all real-world hyperbaric work environments.
