Visual Evoked Responses for Divers Breathing Various Gases at Depths to 1200 Feet

Abstract

Visual evoked responses were recorded from men subjected to hyperbaric conditions simulating 400, 700, 900, and 1200 ft of seawater in a saturation dive conducted at the Institute for Environmental Medicine, University of Pennsylvania, Philadelphia, Pa. Various breathing mixtures were used. At any given depth the VERs were the same for helium-oxygen and neon- oxygen but were sizeably reduced with nitrogen-oxygen, both in amplitude and in regularity. The possibility of an overall loss in VER amplitude with depth deserves further study since one subject did show such a decrement while the other did not.
