Discrepancies Between Autoregulation and CO2 Reactivity of Cerebral Vessels
the stimulus employed to test it; b) the threshold chosen to separate normal and abnormal responses, and the statistical basis for choosing such a threshold. Beside the errors of the method one should consider that the stimuli are seldom pure, since some COg change usually accompanies changes in blood pressure and specially - vice-versa; furthermore, during a test situation a true steady state is often difficult to obtain.
