[Changes in nerve conduction velocity as a result of hyperbaria in man]

Nervous conduction was measured in 27 subjects before and after compression in ternary mixture (helium, nitrogen and oxygen) ranging from 5,5 to 12 ATA. Among the eleven parameters studied, three showed an acceleration of the nervous conduction in the distal part of the sensitive and motor fibers. Although no precise mechanism can be established, different factors, in particular the role of ischemia, are discussed.
