REG was measured in 19 healthy volunteers during control and a 15-degree head-down tilt (HDT), which caused an increase in ICP. We developed an algorithm for automatically calculating P1 and P2 from the REG pulse waveform. The result was compared to manual measurements during control and HDT positions. The automatic determination of the peaks’ time instants was considered a series of two-class decision problems in ±15-ms-wide sliding decision windows. We achieved an accuracy of 0.9826, a sensitivity of 0.7727, and a specificity of 0.9902. We used the correlation coefficient between manual measurements and automated data and the normalized mean absolute error (NMAE) metric to characterize the precision of peak amplitude value estimation. We achieved a high correlation (> 0.8) in 92% of all tests, and NMAE < 0.3 in 96%. The remaining cases were analyzed using Bland-Altman plots to uncover the main causes of differences. We tested the hypothesis of increasing P2 peak amplitude during HDT compared to the control position. In the female group, the number of significant increases was 4 out of 6 (67%), both in manual and automatic measurements. In the case of the male group’s manual measurements, 12 of 13 (92%), and the automatic calculation gave 10 of 13 (77%). The significance is to switch from invasive ICP to noninvasive REG to have the same information for decision-making at the bedside to save the lives of neurocritical care patients. Future REG correlation studies suggested using REG in neurocritical care monitoring, space research, and military medical practice. true NATIONAL 2026 true true true true true false NONE 2026-09-25 false 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 false false false false 2026-05-19T06:58:29.501+0000 Magyar Honvédség Egészségügyi Központ; Repülő- és Űrorvosi Tanszék (SZTE / SZAOK) 2 21 2 4 0 false Language 10002 /api/language/10002 Angol English true 2 true PersonAuthorship 133914408 /api/authorship/133914408 1 0.25 true false false Author 10013215 /api/author/10013215 Pintér István true 10013215 true Pinter Istvan true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 133914409 /api/authorship/133914409 2 0.25 false false false Bagany Mihaly true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 133914410 /api/authorship/133914410 3 0.25 false false false Author 10022416 /api/author/10022416 Szabó Sándor András true 10022416 true Szabo Sandor true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 133914411 /api/authorship/133914411 4 0.25 false true false Bodo Michael true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PublicationIdentifier 31394425 /api/publicationidentifier/31394425 PlainSource 6 /api/publicationsource/6 PublicationSourceType 10001 /api/publicationsourcetype/10001 true true true DOI DOI https://doi.org/@@@ true true 6 true IDENTICAL 10.21467/ijm.4.1.9492 https://doi.org/10.21467/ijm.4.1.9492 false true PublicationIdentifier 31394426 /api/publicationidentifier/31394426 PlainSource 40 /api/publicationsource/40 PublicationSourceType 10006 /api/publicationsourcetype/10006 true true true Egyéb URL Other URL @@@ true true 40 true IDENTICAL https://journals.aijr.org/index.php/ijm/article/view/9492 https://journals.aijr.org/index.php/ijm/article/view/9492 false true /api/publication/36935295 <div class="JournalArticle Publication long-list"> <div class="authors"> <img title="Forrásközlemény" style="float: left" src="/frontend/resources/grid/publication-core-icon.png"> <div class="autype autype0"> <span class="author-name" mtid="10013215"><a href="/gui2/?type=authors&mode=browse&sel=10013215" target="_blank">Pinter Istvan (<span class="authorship-author-name">Pintér István</span> <span class="authorAux-mtmt"> Jelfeldolgozás, gépi tanulás</span>) </a> </span> ;&nbsp;&nbsp;&nbsp; <span class="author-name" >Bagany Mihaly </span> ;&nbsp;&nbsp;&nbsp; <span class="author-name" mtid="10022416"><a href="/gui2/?type=authors&mode=browse&sel=10022416" target="_blank">Szabo Sandor (<span class="authorship-author-name">Szabó Sándor András</span> <span class="authorAux-mtmt"> Repülőorvostan, belgyógyászat</span>) </a> </span> <span class="author-affil"><span title="Szegedi Tudományegyetem">SZTE</span>/<span title="Szent-Györgyi Albert Orvostudományi Kar">SZAOK</span>/Repülő- és Űrorvosi Tanszék; Magyar Honvédség Egészségügyi Központ</span> ;&nbsp;&nbsp;&nbsp; <span class="author-name" >Bodo Michael </span> </div> </div> <div class="title"><a href="/gui2/?mode=browse&params=publication;36935295" target="_blank">Automatic Calculation of the Rheoencephalographic Pulse Wave Peaks: The First Results</a></div> <div> <span class="journal-title">International Journal of Methodology</span> : <span class="journal-volume">1</span> <span class="page"> pp 1-15 </span> <span class="year">(2026)</span> </div> <div class="pub-footer"> <span class="language" xmlns="http://www.w3.org/1999/html">Nyelv: Angol | </span> <span class="identifiers"> <span class="id identifier oa_none" title="none"> <a style="color:blue" title="10.21467/ijm.4.1.9492" target="_blank" href="https://doi.org/10.21467/ijm.4.1.9492"> DOI </a> </span> <span class="id identifier oa_none" title="none"> <a style="color:blue" title="https://journals.aijr.org/index.php/ijm/article/view/9492" target="_blank" href="https://journals.aijr.org/index.php/ijm/article/view/9492"> Egyéb URL </a> </span> </span> <div class="mtid"><span class="long-pub-mtid">Közlemény: 36935295</span> | <span class="status-data status-APPROVED"> Nyilvános </span> Forrás | <span class="type-subtype">Folyóiratcikk ( Konferenciaközlemény ) </span> | <span class="pub-category">Tudományos</span> | <span class="publication-sourceOfData"></span> </div> <div class="lastModified">Utolsó módosítás: 2026.03.02. 10:43 Zachár Krisztina (M.
