[Short-term action of high carbon monoxide concentrations on the psychophysiological functions of a human operator]. / Issledovanie kratkovremennogo vozdeistviia vysokikh kontsentratsii okisi ugleroda na nekotorye psikhofiziologicheskie funktsii cheloveka-operatora.

Experiments on volunteers, aged 26-40, demonstrated that a 10-minute exposure to carbon monoxide at a concentration of 900 +/- 20 mg/m3 caused a significant decline of the quality of their operator's function. The task they performed was a two-dimensional compensatory tracking task combined with mental arithmetic. Some of the test subjects showed symptoms of mild CO intoxication which preceded disorders in their work and were accompanied by an increase of HbCO to 10 +/- 0.57%. Such an exposure to CO should be regarded as hazardous since it may increase the probability of erroneous actions particularly, of the flying personnel.
