'''1. Critical flicker fusion frequency could be a measure of cognitive decrement due to inert gas narcosis in divers.'''

'''Citation/s:'''1.Lafère P, Hemelryck W, Germonpré P, Matity L, Guerrero F, Balestra C. Early detection of diving-related cognitive impairment of different nitrogen-oxygen gas mixtures using critical flicker fusion frequency. Diving Hyperb. Med. 2019 Jun 1;49:119-26. '''Lead author's name and fax: '''Pierre Lafere doc.lafere@sfr.fr

'''Three-part Clinical Question:'''For adult divers, does cognitive performance vary under different conditions and can Critical Flicker Fusion Frequency (CFFF) serve as an indicator of threatened cognitive performance. '''Search Terms:''' Critical Flicker Fusion Frequency; Inert Gas Narcosis; cognitive testing

'''The Study:'''Double-blinded crossover concealed randomised controlled trial with intention-to-treat. '''The Study Patients:''' Fit volunteer divers. '''Control group''' (N = 8; analysed): Dry chamber dive breathing compressed air to 30 msw for 22 minutes '''Experimental group''' (N = 8; analysed): As above but breathing 40% oxygen (EAN).

'''The Evidence:'''

Multiple regression and ANOVA results given in paper.

'''Comments:''' 1. Many outcomes subject to wide statistical analysis. No simple event or mean -based outcomes. 2. CFFF and a measure of cognitive performance broadly agree and suggest a decline in cognition at depth that may be assessable with CFFF. 3. Oxygen-dependent activation of the prefrontal cortex accompanies these changes.
