Abstract Background Intracranial pressure (ICP) monitoring is a core component of neurosurgical diagnostics. With the introduction of telemetric monitoring devices in the last years, ICP monitoring has become feasible in a broader clinical setting in

Background Repetitive transient intracranial pressure waveform elevations up to 50 mmHg (ICP B-waves) are often used to define pathological conditions and determine intracranial pressure-reducing treatment indications. We recently showed that nocturn

Background: The standard lumbar puncture position involves maximum flexion of both lumbar and cervical spine. The cerebrospinal fluid opening pressure (CSFop) is measured in a horizontal position. This study investigated if flexion of hip and neck bo

Intracranial pressure (ICP) is a commonly collected neurocritical parameter, but accurate signal modelling remains challenging. The goal of this project was to mimic clinical ICP waveforms using a physical model.A physical head model was developed. T

Empirical Mode Decomposition-Based Method for Artefact Removal in Raw Intracranial Pressure Signals

Autor: Marianne Juhler, Isabel Martinez-Tejada, Jens E. Wilhjelm, Morten Andresen

Publikováno v: Acta Neurochirurgica Supplement ISBN: 9783030594350

Intracranial pressure (ICP) signals are often contaminated by artefacts and segments of missing values. Some of these artefacts can be observed as very high and short spikes with a physiologically impossible high slope. The presence of these spikes r
