While mainly used to detect episodes of intracranial hypertension, the ICP signal is also indicative of the volume-pressure relationship within the cerebrospinal system, often referred to as intracranial compliance (ICC). Several ICP signal descriptors have been proposed in the literature as surrogates of ICC, but the possibilities of combining these are still unexplored. In the present study, a rapid ICC assessment consisting of a 30-degree postural shift was performed on a cohort of 54 brain-injured patients. 73 ICP signal features were calculated over the 20 minutes prior to the ICC test. After a selection step, different combinations of these features were provided as inputs to classification models. The goal was to predict the level of induced ICP elevation, which was categorized into three classes: less than 7 mmHg (\u201cgood ICC\u201d), between 7 and 10 mmHg (\u201cmedium ICC\u201d), and more than 10 mmHg (\u201cpoor ICC\u201d). A logistic regression model fed with a combination of 5 ICP signal features discriminated the \u201cpoor ICC\u201d class with an area under the receiving operator curve (AUROC) of 0.80 (95%-CI: [0.73\u20140.87]). The overall one-versus-one classification task was achieved with an averaged AUROC of 0.72 (95%-CI: [0.61\u20140.83]). Adding more features to the input set and\/or using nonlinear machine learning algorithms did not significantly improve classification performance. This study highlights the potential value of analyzing the ICP signal independently to extract information about ICC status. At the patient\u2019s bedside, such univariate signal analysis could be implemented without dependence on a specific setup.<\/jats:p>","DOI":"10.1371\/journal.pone.0316167","type":"journal-article","created":{"date-parts":[[2024,12,30]],"date-time":"2024-12-30T18:37:26Z","timestamp":1735583846000},"page":"e0316167","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":2,"title":["Cerebral compliance assessment from intracranial pressure waveform analysis: Is a positional shift-related increase in intracranial pressure predictable?"],"prefix":"10.1371","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-4884-3164","authenticated-orcid":true,"given":"Donatien","family":"Leg\u00e9","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre-Henri","family":"Murgat","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Russell","family":"Chabanne","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-4869-866X","authenticated-orcid":true,"given":"Kevin","family":"Lagarde","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cl\u00e9ment","family":"Magand","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Fran\u00e7ois","family":"Payen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marion","family":"Prud\u2019homme","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9105-8862","authenticated-orcid":true,"given":"Yoann","family":"Launey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7283-6793","authenticated-orcid":true,"given":"Laurent","family":"Gergel\u00e9","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2024,12,30]]},"reference":[{"issue":"1","key":"pone.0316167.ref001","doi-asserted-by":"crossref","first-page":"67","DOI":"10.1227\/NEU.0000000000000575","article-title":"Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI): A Prospective Longitudinal Observational Study","volume":"76","author":"AIR Maas","year":"2015","journal-title":"Neurosurgery"},{"issue":"9","key":"pone.0316167.ref002","doi-asserted-by":"crossref","first-page":"1189","DOI":"10.1007\/s00134-014-3369-6","article-title":"Consensus summary statement of the International Multidisciplinary Consensus Conference on Multimodality Monitoring in Neurocritical Care: A statement for healthcare professionals from the Neurocritical Care Society and the European Society of Intensive Care Medicine","volume":"40","author":"P Le Roux","year":"2014","journal-title":"Intensive Care Medicine"},{"key":"pone.0316167.ref003","unstructured":"Cnossen, MC, Huijben, JA, van der Jagt, M, et al.
