Fig. 3: Correlation metrics of autoregulation.
From: Spinal cord vascular autoregulation: key concepts and opportunities to improve management
a Mean arterial pressure and b spinal cord blood flow recorded over an extended period. Five-minute periods are processed to obtain the correlation between MAP and blood flow. c Intact autoregulation results in a correlation close to 0, while d impaired autoregulation results in a correlation closer to 1. e Plotting correlation of each period against the mean MAP of that chunk often shows an MAP at which correlation is minimal (and thus autoregulation is maximal). This may be the optimal MAP target for that patient.
