Shows intact cerebralautoregulation where, within the autoregulatory range between 50 and 150 mmHg ABP (x-axis), cerebral blood flow (y-axis) remains stable. There is no correlation between pressure and flow. The Mx is less than 0.3.
脑血管自主调节功能 (CA) 受损Demonstrates impaired cerebral autoregulation where flow (Y-axis) is entirely dependent on pressure (x-axis). There is a positive correlation between pressure and flow. The Mx is greater than 0.3. CHINA International Neuroscience Institute ICU
