[The function of the fluid compartment. Part I]

P Nádvornik, J Duros, D Tertsch

    Zentralblatt Fur Neurochirurgie
    |January 1, 1980
    PubMed
    Summary

    The cerebrospinal fluid space volume and pressure dynamics are key to understanding intracranial pressure. The pressure/volume index (PVI) quantifies this relationship, offering insights into cranial cavity compensation.

    Area of Science:

    • Neurology
    • Physiology
    • Biomedical Engineering

    Context:

    • The Monro-Kellie doctrine describes the pressure-volume dynamics within the fixed cranial vault.
    • Understanding cerebrospinal fluid (CSF) dynamics is crucial for diagnosing and managing neurological conditions.

    Purpose:

    • To introduce the concept of cerebrospinal fluid space expansion.
    • To explain the relationship between volume and pressure changes in the cranial cavity.
    • To highlight the importance of the pressure/volume index (PVI) in assessing intracranial dynamics.

    Summary:

    • Expansion of the cerebrospinal fluid space is conceptualized based on characteristic volume-pressure changes within the closed cranial cavity.
    • Physical laws governing the interplay of brain, CSF, and blood vessels are considered.
    • The pressure/volume index (PVI) is presented as a quantifiable measure of intracranial space filling and compensatory capacity.

    Impact:

    • Provides a novel framework for understanding intracranial pressure regulation.
    • Offers a measurable parameter (PVI) for assessing the elasticity and compliance of the cerebrospinal fluid space.
    • Enhances diagnostic capabilities for conditions involving altered intracranial volume and pressure.
