The influence of carbogen on susceptibility to TTS. 1989

F Lindgren, and H Dengerink, and A Axelsson

Department of Audiology, University of Gothenburg, Sweden.

A group of 20 male subjects were exposed to noise in each of four separate conditions. In two conditions they inhaled carbogen (95% oxygen, 5% carbon-dioxide). In two others they inhaled compressed air. In two conditions they were exposed to noise after inhalation and in two they were exposed to noise during the inhalation. The results indicated that carbogen inhalation reduced the magnitude of TTS but only in the 'During' condition.
