Invasive and Noninvasive Intracranial Pressure Pulse Waveform in Neurocritical Care Patients with Different Cranium Integrity.

ABSTRACT:

Background

Pulse shape index (PSI) is a novel artificial intelligence-supported parameter that evaluates the pressure-volume compensatory reserve of the craniospinal system through intracranial pressure (ICP) pulse waveform classification. This study assessed the agreement between PSI derived from invasive ICP monitoring (PSI_ICP) and noninvasive brain4care (B4C) sensor signal (PSI_B4C) and investigated the influence of cranial integrity, age, and internal jugular vein (IJV) compression on PSI values.

Methods

Simultaneous ICP and B4C monitoring was performed in 47 adult patients ( age: 43 (30) years) before and during IJV compression. Patients were grouped by cranial integrity: intact skull bone (n = 17), large skull fractures or craniotomies (n = 17), an
