      Backround: Nitrogen narcosis impairs cognitive function, a fact relevant during SCUBA-diving. Oxygen-enriched air (nitrox) became popular in recreational diving, while evidence of its advantages over air is limited. AIM: Compare effects of nitrox28 and air on two psychometric tests. METHODS: In this prospective, double-blind, open-water study, 108 advanced divers (38 females) were randomized to an ...

    • Objective vs. Subjective Evaluation of Cognitive Performance During 0.4-MPa Dives Breathing Air or NitroxPeer reviewedClosed access

      Article scientifique
      BACKGROUND: Divers try to limit risks associated with their sport, for instance by breathing enriched air nitrox (EANx) instead of air. This double blinded, randomized trial was designed to see if the use of EANx could effectively improve cognitive performance while diving. METHODS: Eight volunteers performed two no-decompression dry dives breathing air or EANx for 20 min at 0.4 MPa. Cognitive ...
