Objective: In this review, we detail the impact of environmental stress on cognitive and
military task performance and highlight any individual characteristics or interventions which …

Exposure to the underwater environment for pleasure or work poses many challenges on
the human body including thermal stress, barotraumas, decompression sickness as well as …

Diving narcosis results from the complex interaction of gases, activities, and environmental
conditions. We hypothesized that these interactions could be separated into their component …

Backround: Nitrogen narcosis impairs cognitive function, a fact relevant during SCUBA-
diving. Oxygen-enriched air (nitrox) became popular in recreational diving, while evidence …

Methods Eight male volunteers performed, in random order, two dry chamber dives
breathing either air or EANx40 (40% O 2− 60% nitrogen) for 20 minutes (min) at 0.4 MPa …

Insight into human physiology is key to maintaining diver safety in underwater operational
environments. Numerous hazardous physiological phenomena can occur during the …

Divers are at enhanced risk of suffering from acute cognitive deterioration because of the
low ambient temperatures and the narcotic action of inert gases inspired at high pressures …

Bubble formation during scuba diving might induce decompression sickness. This
prospective randomised and double-blind study included 108 advanced recreational divers …

Background The narcotic effect of hyperbaric nitrogen is most pronounced in air-breathing
divers because it impairs diver's cognitive and behavioral performance, and limits the depth …
