A 2008 paper published by the AAUS failed reports on another study that failed to find a connection between using EANx and diver fatigue. In a double blind study by San Jose University, San Jose, California, there was no correlation between gas used and diver’s fatigue perceptions. Some subjects said they could tell which gas they were using, but were wrong 66 percent of the time. Findings did note an “health advantage” but not one of meaningful significance.
