PERFORMANCE DECREMENT CAUSED BY MILD CARBON MONOXIDE LEVELS ON TWO VISUAL FUNCTIONS

Six subjects participated in an experiment to determine the effects of mild levels of CO (4 to 8% COHB) on the time necessary to detect static and dynamic visual targets. In the static phase, the subject adapted for one minute to an illumination of 17 foot-lamberts and detected low-contrast targets when the ambient illumination dropped to .02 foot-lambert. In the dynamic phase, the illumination was constant at 6 foot-lamberts and the subject detected the targets moving into the visual field. There was a significant decrement in target detection time due to CO for the dynamic task, indicating some constriction of the visual field. The CO-related decrement for the static task was not statistically significant. /Author/
