Samenvatting
Visual sensitivity to differences in light intensity was employed as a sensitive index of (1) the effects of carbon monoxide, and of (2) the persistence of these effects during elimination of this gas while ordinary air, oxygen and carbogen mixtures were breathed. Recovery from detrimental effects of CO on this visual function lags behind the elimination of CO from the blood, the effect apparently being determined by the duration of the presence of CO in the blood as well as its concentration.
