title: [Changes in acoustically evoked brain potentials during oxygen breathing at normal and increased pressures].
abstract: Acoustically evoked potentials of the human brain were studied when breathing pure oxygen at a normal and positive pressure. An exposure to pure oxygen at a normal pressure reduced the amplitude of evoked potentials. This effect was more pronounced at a positive oxygen pressure. The after-effect was prolonged due to the influence of an increased oxygen concentration. During an exposure to the air at a positive pressure the reduction of the amplitude was smaller and reached the pretest level as soon as the pressure returned to normal. Evoked potentials are a sensitive indicator of the effect of an altered atmosphere on the central nervous system and the sensory system.
