脑血动力学对短期与持续的减低脑灌注压的反应含有脑血流自动调节状态信息。故数学模拟可有助阐明多普勒超声获取的颅内压与血压倾向的指标。这是自动调节储备有用的临床试验。方法是依赖压力、血流互相作用的时间,脑血容量和脑脊液采用非线性不同方程作成模型。模型模拟动脉血液的流入与贮存改变,脑自动调节,小动脉与毛细血管血流的控制,因ICP(颅内压)改变,CSF贮存和重吸收调节的静脉血贮存和静脉血的流出。模型采取模拟短期或持续的脑灌注
The response of cerebral hemodynamics to short-term and sustained decreases in cerebral perfusion pressure contains information on the automatic regulation of cerebral blood flow. Therefore, mathematical simulation can help clarify the indicators of intracranial pressure and blood pressure tendency obtained by Doppler ultrasound. This is a useful clinical trial that automatically regulates reserves. The method relies on stress, the time of blood flow interaction, the volume of cerebral blood and cerebrospinal fluid using different nonlinear equations to make the model. The model simulates changes in arterial blood influx and storage, brain autoregulation, arteriolar and capillary blood flow control, venous blood storage regulated by changes in ICP (intracranial pressure), CSF storage and reabsorption, and venous blood outflow. The model was taken to simulate short-term or continuous cerebral perfusion
