Expansion of the cerebrospinal-fluid space is a new conception introduced in view of the fact that in the closed cranial cavity in case of an increase in cerebrospinal fluid the relation volume/pressure undergoes characteristic changes. The physical laws resulting from this have already been considered in the Monro-Kellie doctrine and concern the three main parts of the cranial cavity: brain, cerebrospinal fluid, and vessels. The capability of compensation, the compliance and the elasticity or elastantia of the cerebrospinal-fluid space can be measured on the basis of the dynamic changes proceeding in the space, the pressure/volume index (PVI) being a measure of the degree of filling of the intracranial space.
脑脊液空间的扩张是鉴于在封闭的颅腔内脑脊液增加时容积/压力关系会发生特征性变化而引入的一个新概念。由此产生的物理定律已在孟罗-凯利学说中有所考虑,涉及颅腔的三个主要部分:脑、脑脊液和血管。脑脊液空间的代偿能力、顺应性以及弹性或弹性系数可根据该空间内发生的动态变化来测量,压力/容积指数(PVI)是颅内空间充盈程度的一种度量。
