This study evaluates patient transport conditions on a stretcher subjected to vertical vibration excitation from road unevenness. Using an eight-degree-of-freedom numerical model, we analyze the construction parameters of a medical stretcher\u2019s support and vehicle suspension. Actual experimental data from an emergency vehicle were utilized to assess the vibration conditions experienced by both the stretcher and the ambulance floor. The model is adjusted based on measurements, specifically targeting the main vibration modes. The investigation involves determining temporal responses for vertical accelerations and characterizing vibration modal parameters under various transportation conditions. Notably, several system natural frequencies fall within the range of human body frequencies, making them susceptible to mechanical excitation, particularly in the human neck, abdomen, and spine. A sensitivity analysis underscores the influence of medical stretcher support structure parameters on patient comfort. Increasing support stiffness, which alters the stretcher\u2019s natural frequency, and damping coefficient reduce vibration propagation between the vehicle and the patient. Additionally, the research predicts the model\u2019s dynamic behavior on roads with low-quality pavement, indicating vibrational amplitudes that could potentially be discomforting and unhealthy for individuals. The study illustrates a vibration exposure period on a class E road, revealing that transportation longer than 25\u2009min may cause damage to patient health.<\/jats:p>","DOI":"10.1177\/09544119241240908","type":"journal-article","created":{"date-parts":[[2024,4,2]],"date-time":"2024-04-02T02:21:30Z","timestamp":1712024490000},"page":"508-519","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Assessing patient transport conditions during ambulance transit"],"prefix":"10.1177","volume":"238","author":[{"given":"Pedro Vitor","family":"Uchima","sequence":"first","affiliation":[{"name":"Department of Mobility Engineering, Federal University of Santa Catarina, Joinville, Santa Catarina, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3853-0758","authenticated-orcid":false,"given":"S\u00e9rgio Junichi","family":"Idehara","sequence":"additional","affiliation":[{"name":"Department of Mobility Engineering, Federal University of Santa Catarina, Joinville, Santa Catarina, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,4,1]]},"reference":[{"key":"bibr1-09544119241240908","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-66284-3_62"},{"key":"bibr2-09544119241240908","first-page":"33","volume":"94","author":"Shimizu N","year":"2018","journal-title":"Chiba Medical J"},{"key":"bibr3-09544119241240908","first-page":"1","volume":"2013","author":"Yang M","year":"2013","journal-title":"Abstr Appl Anal"},{"issue":"1","key":"bibr4-09544119241240908","first-page":"24","volume":"6","author":"Lekveishvili R","year":"2021","journal-title":"Int Sci J Trans Motauto World"},{"key":"bibr5-09544119241240908","unstructured":"ISO 2631-1:1997.
