Pathobiochemistry of CO poisoning.
A hypothesis for the pathobiochemical mechanism of CO poisoning, amenable to in vivo testing with optical reflectance spectrophotometry, is presented. It differs from the classical formulation in which loss of cytochrome c oxidase function is attributed entirely to O2 depletion, by including ligation and oxygenation of CO as essential components of the inhibitory process.
