Despite differences in scopes and ventilation needle mounting positions, the same jet pressures are typically used. We hypothesized that different scopes and scope configurations would affect distal airway pressure magnitude and homogeneity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>A laboratory investigation of distal airway pressures in a lung modelduring low frequency jet ventilation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A three\u2010dimensional airway model based on the computed tomography scan of a 15\u2010year old healthy male was fabricated with pressure transducers at the fifth airway generation. A laryngoscope and a subglottiscope were each mounted in the model coaxial with the trachea. Parameters including scope depth and needle mounting position were adjusted, and the effects on distal airway pressure were recorded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Changing the scope depth from 1 to 3\u2009cm past the laryngeal inlet had a limited effect on distal airway pressure. Needle mounting angle in the laryngoscope strongly influenced distal airway pressure, with a 7\u00b0 angle change yielding a 67.5% increase. Compared to a loose needle centered in the trachea 1\u2009cm past the laryngeal inlet, the subglottiscope and laryngoscope showed up to 16% and 150% increases in distal airway pressure, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Different scopes or changes in the configuration, such as the needle angle, strongly influence distal airway pressure. Our findings indicate that different jet pressures are required for different scopes and that a stable needle mount is a critical design consideration to prevent changes in minute ventilation due to needle movement.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of Evidence<\/jats:title><jats:p>NA (Basic Research) <jats:italic>Laryngoscope<\/jats:italic>, 131:E354\u2013E357, 2021<\/jats:p><\/jats:sec>","DOI":"10.1002\/lary.28923","type":"journal-article","created":{"date-parts":[[2020,7,27]],"date-time":"2020-07-27T19:33:32Z","timestamp":1595878412000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Effects of Laryngoscope Shape and Needle Position on Distal Airway Pressure in Jet Ventilation"],"prefix":"10.1002","volume":"131","author":[{"given":"Joshua","family":"Pertile","sequence":"first","affiliation":[{"name":"Department of Bioengineering University of Colorado Denver, Anschutz Medical Campus  Aurora Colorado U.S.A."},{"name":"Department of Computer Science and Engineering Colorado Mesa University  Grand Junction Colorado U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michelle","family":"Mellenthin","sequence":"additional","affiliation":[{"name":"Department of Bioengineering University of Colorado Denver, Anschutz Medical Campus  Aurora Colorado U.S.A."},{"name":"Department of Computer Science and Engineering Colorado Mesa University  Grand Junction Colorado U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer","family":"Wagner","sequence":"additional","affiliation":[{"name":"Department of Bioengineering University of Colorado Denver, Anschutz Medical Campus  Aurora Colorado U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emily M.","family":"DeBoer","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, School of Medicine University of Colorado  Aurora Colorado U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5162-2537","authenticated-orcid":false,"given":"Daniel","family":"Fink","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, School of Medicine University of Colorado  Aurora Colorado U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1583-6762","authenticated-orcid":false,"given":"Bradford","family":"Smith","sequence":"additional","affiliation":[{"name":"Department of Bioengineering University of Colorado Denver, Anschutz Medical Campus  Aurora Colorado U.S.A."},{"name":"Department of Pediatrics, School of Medicine University of Colorado  Aurora Colorado U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,7,27]]},"reference":[{"doi-asserted-by":"publisher","key":"e_1_2_6_2_1","DOI":"10.1152\/jappl.1990.69.3.956"},{"key":"e_1_2_6_3_1","first-page":"880","article-title":"Intermittent positive\u2010pressure hyperventilation with high inflation pressures produces pulmonary microvascular injury in rats","volume":"132","author":"Dreyfuss D","year":"1985","journal-title":"Am Rev Respir Dis"},{"key":"e_1_2_6_4_1","first-page":"312","article-title":"Severe impairment in lung function induced by high peak airway pressure during mechanical ventilation","volume":"135","author":"Kolobow T","year":"1987","journal-title":"Am Rev Respir Dis"},{"doi-asserted-by":"publisher","key":"e_1_2_6_5_1","DOI":"10.1164\/ajrccm\/148.5.1194"},{"doi-asserted-by":"publisher","key":"e_1_2_6_6_1","DOI":"10.1016\/S0002-9440(10)63747-9"},{"doi-asserted-by":"publisher","key":"e_1_2_6_7_1","DOI":"10.1186\/s13104-015-1175-z"},{"unstructured":"PatelS MiaoJH Yetisuki E Majmundar SH.
