Electronic device and method for evaluating autoregulatory pattern of cerebral blood flow

An electronic device for evaluating an autoregulatory pattern of cerebral blood flow, comprising:

• a transceiver;
• and
• a processor, coupled to the transceiver, and configured to:
• receive a first data set through the transceiver, wherein a data point in the first data set comprises blood pressure and blood flow velocity corresponding to the blood pressure;
• group each data point in the first data set according to a plurality of blood pressure ranges to generate a plurality of data groups respectively corresponding to the plurality of blood pressure ranges;
• calculate a plurality of average values of the blood flow velocity respectively corresponding to the plurality of data groups;
• perform a first linear regression operation on the plurality of average values of the blood flow velocity to generate a first regression line;
• calculate a first slope of the first regression line to obtain a first indicator;
• group a plurality of data sets comprising the first data set according to the first indicator to generate a plurality of autoregulatory pattern groups;
• receive a second data set through the transceiver, and determine that the second data set corresponds to one of the plurality of autoregulatory pattern groups;
• and
• output an autoregulatory pattern of the second data set, wherein the autoregulatory pattern corresponds to one of the plurality of autoregulatory pattern groups.
