Ultrasonic system data segment choosing method, storage medium and ultrasonic device

Abstract

The invention discloses an ultrasonic system data segment choosing method, a storage medium and an ultrasonic device. The method comprises the steps of collecting brain blood flow data and continuous blood pressure data, wherein sampling points of the brain blood flow data and the continuous blood pressure data are synchronous; judging whether the brain blood flow data and the continuous blood pressure data meet a preset segment choosing condition or not; and if the preset segment choosing condition is met, automatically choosing sampling data segments of the brain blood flow data and the continuous blood pressure data according to a preset rule. According to the method, while the brain blood flow data and the continuous blood pressure data are collected, whether the collected data meets the preset segment choosing condition or not is judged; and when the preset segment choosing condition is met, the sampling data segments are automatically chosen according to the preset segment choosing rule, so that automatic choice of the brain blood flow data and the continuous blood pressure data is realized. Meanwhile, corresponding choice is performed while the brain blood flow data and the continuous blood pressure data are collected, so that the timeliness of the chosen sampling data segments is ensured.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a method for selecting segments of ultrasonic system data, a storage medium and ultrasonic equipment. Background technique [0002] Cerebral blood flow automatic regulation function (hereinafter referred to as "blood flow regulation function") refers to changes in cerebral blood flow through compensatory expansion or contraction of arterioles and capillary smooth muscles when mean arterial pressure (MABP) fluctuates within a certain range. Vascular resistance (CVR), the physiological function that keeps cerebral blood flow (CBF) relatively constant. The blood flow regulation function can be expressed by CBF=MABP / CVR. For normal people, when the mean arterial pressure fluctuates within the range of 50mmHg-170mmHg, the blood flow regulation function can make MABP change in direct proportion to CVR, thereby ensuring that CBF remains relatively constant. For stroke patient...

AI Technical Summary

Problems solved by technology

For stroke patients, due to atherosclerosis, the diastolic function of blood vessels is impaired, and the upper and lower limits of blood flow regulation function are higher than normal people, so they can tolerate high blood pressure, but they cannot tolerate low blood pressure.

At this time, if the use of drugs causes the blood pressure to fall below the lower limit of the blood flow regulation function range, the CBF will passively decrease along with the MABP, which will cause the increase of the infarct area of ​​the focal brain tissue and the deterioration of the neurological function, and even lead to the death of the patient in severe cases.
