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.
