National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Effects of CO on Vigilance Performance -- Effects of Low Level Carbon Monoxide on Divided Attention, Pitch Discrimination, and the Auditory Evoked Potential.

PB274219

Publication Date	1976
Personal Author	Putz, V. R.; Johnson, B. L.; Setzer, J. V.
Page Count	68
Abstract	Behavioral and neurological aspects of low level exposure to carbon monoxide are investigated in 20 males and 10 females, aged 18-26 years, in a double-blind study. The behavioral measures of performance include: a compensatory tracking task to measure hand-eye coordination; a visual peripheral monitoring task to measure light intensity discrimination; and an auditory monitoring task to measure tone discrimination. Neurological assessment consists of an analysis of the components of the auditory evoked response. Carboxyhemoglobin levels of 1, 3, and 5% are obtained at the end of the fourth hour of exposure for carbon monoxide exposures of 5, 35 and 70 ppm, respectively. Statistically significant decrements in performance are noted at carboxyhemoglobin levels of 5%, the NIOSH recommended exposure limit.
