Why the study?
CFFF has shown conflicting or paradoxical results for measuring cognitive effects of gas mixtures at depth, prompting evaluation of an automatic CFFF method and its utility for monitoring gas narcosis in divers.
Does critical flicker fusion frequency (CFFF) change when breathing different gas mixtures at depth compared to air at sea level?
Does critical flicker fusion frequency (CFFF) change when breathing different gas mixtures at depth compared to air at sea level?
Critical flicker fusion frequency does not appear to be a sensitive tool for measuring gas narcosis in divers under laboratory conditions.
Automated CFFF may aid narcosis assessment in divers; leaves open reliability and clinical adoption pending validation.
