However, some limitations of invasive techniques for ICP monitoring to acknowledge are the risk for complications and the lack of robust evidence supporting individualized ICP safety thresholds. Cerebrospinal compliance (CSC) may serve as a more reliable indicator of brain health than ICP alone. Previously, intracranial compliance (Ci), was described as a mathematical model from invasive ICP to assess CSC, using ICP waveform amplitudes and cerebral arterial blood volume (CaBV) waveform amplitudes via transcranial Doppler (TCD). This study aimed to compare Ci with a surrogate parameter based on CaBV waveform amplitudes and pulsatile micrometric skull waveforms (Skw) amplitudes.

ICP waveform (from invasive ICP probes) and Skw (from noninvasive B4C) were analyzed to extract pulse amplitudes, whereas TCD provided cerebral blood velocities from the middle cerebral arteries for CaBV calculation. CSC was measured using the volume/pressure relationship, with CaBV amplitude serving as the volume surrogate, and ICP and B4C pulse amplitudes as surrogates for ICP values.
