(A) A stylized graph of the relationship between cerebral blood flow and mean arterial pressure is linear beyond the upper and lower limits of autoregulation (indicated by the red dashed lines and arrows). Between the upper and lower limits, autoregulation compensates for increases or decreases in mean arterial pressure to maintain a constant cerebral blood flow. (B) Real-life data, identifying the limits of autoregulation through static assessment is not as straightforward.
