Abstract

The response of cerebral blood flow to increases and decreases in blood pressure have been reported to differ. The potential impact of this on the commonly used linear-time-invariant modelling of only spontaneous changes in blood pressure has so far not been tested. Results show that this could have a major impact on quantitative measures of cerebral autoregulaton.

脑血流自动调节在血压自发升高和自发降低的序列中有区别吗?
据报道,脑血流量对血压升高和降低的反应是不同的。到目前为止,这对血压自发变化的常用线性时不变模型的潜在影响尚未得到测试。结果表明,这可能对大脑自我调节的定量测量产生重大影响。
