What Researchers Did
During a series of dry chamber dives using compressed heliox, researchers observed hand discomfort in attendants and a wet diver and later implemented a dry glove assembly to prevent helium absorption.
What They Found
Initially, five attendants and one wet diver experienced eight episodes of atypical hand discomfort, with symptoms resolving within 48 hours and no response to hyperbaric oxygen therapy. After adopting dry gloves, the incidence of hand discomfort among attendants significantly decreased from 25% (5/20) to 2.4% (2/84) (p = 0.005), with less severe and shorter-lasting symptoms.
