Abstract

The invention discloses a method and system for assessing the automatic adjustment ability of cerebral blood flow, relating to the medical field, comprising the following steps: using an ultrasonic external counterpulsation device to perform two external counterpulsation operations on an individual, and applying the external counterpulsation operation twice. During the implementation of the external counterpulsation operation, continuous blood pressure monitoring and cerebral blood flow velocity monitoring are carried out on the individual; using the blood pressure effect separation method, the cerebral blood flow velocity change value and the blood pressure data change value are obtained; using the transfer function method Analyzing and obtaining the relationship between the change value of the cerebral blood flow velocity and the change value of the blood pressure data; according to the relationship between the change value of the cerebral blood flow velocity and the change value of the blood pressure data, evaluating the cerebral blood flow autoregulation ability of the individual . Through the implementation of the present invention, the interference of factors other than blood pressure that affect the change of cerebral blood flow velocity can be eliminated, and the accuracy of evaluation of cerebral blood flow autoregulation ability can be improved.

Description

technical field [0001] The invention relates to the medical field, in particular to a method and system for evaluating the automatic regulation ability of cerebral blood flow. Background technique [0002] The concept of cerebral autoregulation (Cerebral autoregulation, CA) was first proposed by Lassen in 1959, which refers to the ability of cerebral blood flow in the cerebral blood vessels to maintain stability when the blood pressure of the human body fluctuates within a certain range. Autoregulation of cerebral blood flow is an important cerebral protection mechanism to avoid excessive or insufficient blood supply to the brain when blood pressure changes. The assessment methods of cerebral blood flow autoregulation can be divided into two types: static cerebral autoregulation (static CA, sCA) assessment method and dynamic cerebral blood flow autoregulation (dynamic CA, dCA) assessment method. The static cerebral blood flow autoregulation assessment method causes the bloo...
