The following is a list of symptoms which have been applied mainly to acute CO poisoning. Many sources suggest they can be closely related to blood COHb level. Please note that in practice, severity of symptoms DO NOT correlate well with COHb level. This is also true for the longterm, neuropsychological effects of CO poisoning, ie. there is little relationship between the effects and the COHb level at presentation. Thus, any conclusions about COHb from symptoms, or vice versa, should be drawn with the greatest caution! I DO NOT endorse this kind of simplistic approach to the effects of CO poisoning.
