1. A system configured to monitor autoregulation comprising:

  • a medical sensor configured to be applied to a patient and to generate a regional oxygen saturation signal;

    a controller comprising a processor configured to;

    receive the regional oxygen saturation signal and a blood pressure signal;

    determine a cerebral oximetry index (COx) based on the blood pressure signal and the regional oxygen saturation signal;

    apply a data clustering algorithm to cluster COx data points over a range of blood pressures;

    identify a first cluster of COx data points that corresponds to an intact autoregulation zone for the patient; and

    provide a first output indicative of the intact autoregulation zone for the patient.
