Rapid-O2 was modified to enhance ventilation using the Venturi effect during expiration. Methods: To determine the most effective combination of inner catheters (20 gauge [G], 18 G, 16 G, 14 G, and 2-mm inner diameter [ID] transtracheal catheter [TTC]) and insufflation catheters (16 G, 14 G, and 2-mm ID TTC) for achieving optimum ventilation, insufflating and expiratory flows were measured at an oxygen flow rate of 15 L\/min. The insufflating and expiratory pressures were measured at 6\u201315 L\/min. The flows and pressures were measured using a gas flow analyzer. The insufflating and expiratory times were measured using a trachea-lung model to obtain minute volumes. To assess the improvement by modifying the Rapid-O2, minute volumes were measured using the Rapid-O2.Results: The most appropriate inner catheter was 18 G. The insufflating pressures ranged from 97 (2-mm ID TTC) to 377 cmH2O (16 G) at 15 L\/min. During expiration, similar negative pressures of 50 cmH2O were measured in the insufflation catheters at 15 L\/min. At lung compliance of 100 ml\/cmH2O, the minute volumes through a 2-mm ID and 14 G insufflation catheters were 7.0 and 5.37 L\/min, respectively, at 15 L\/min. The minute volumes were significantly greater in modified Rapid-O2.Conclusions: Modified Rapid-O2 provided sufficient minute volumes in adults using a 14 G or 2-mm ID insufflation catheter at 15 L\/min, demonstrating its potential for ventilation in CICO events. <\/jats:p>","DOI":"10.4097\/kja.24095","type":"journal-article","created":{"date-parts":[[2024,9,27]],"date-time":"2024-09-27T06:47:58Z","timestamp":1727419678000},"page":"61-72","update-policy":"https:\/\/doi.org\/10.4097\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Transcatheter ventilation with a modified Rapid-O2 oxygen insufflation device"],"prefix":"10.4097","volume":"78","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1997-8733","authenticated-orcid":true,"given":"Jaewon","family":"Jang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3452-477X","authenticated-orcid":true,"given":"Hye Jin","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1963-8955","authenticated-orcid":true,"given":"Hyun Joo","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5204-3921","authenticated-orcid":true,"given":"Wyun Kon","family":"Park","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2573","reference":[{"volume-title":"","key":"ref1"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1177\/0310057x19886868"},{"volume-title":"","year":"2013","author":"Heard","key":"ref3"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2044.2009.05888.x"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/aeq364"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1097\/00005373-197201000-00006"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198211000-00007"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1213\/00000539-199810000-00032"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1097\/00003246-199402000-00026"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2044.1963.tb13704.x"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/s0361-1124(78)80034-3"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-195809000-00004"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/aep391"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/aes366"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/aeu125"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-199710000-00034"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-195911000-00007"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/aes033"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1111\/aas.12663"}],"container-title":["Korean Journal of Anesthesiology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/ekja.org\/upload\/pdf\/kja-24095.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/ekja.org\/journal\/view.php?doi=10.4097\/kja.24095","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/ekja.org\/upload\/pdf\/kja-24095.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,3]],"date-time":"2025-02-03T00:35:17Z","timestamp":1738542917000},"score":1,"resource":{"primary":{"URL":"http:\/\/ekja.org\/journal\/view.php?doi=10.4097\/kja.24095"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,2,1]]},"references-count":19,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2025,2]]}},"URL":"https:\/\/doi.org\/10.4097\/kja.24095","relation":{},"ISSN":["2005-6419","2005-7563"],"issn-type":[{"type":"print","value":"2005-6419"},{"type":"electronic","value":"2005-7563"}],"subject":[],"published":{"date-parts":[[2025,2,1]]},"assertion":[{"value":"2024-02-07","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-09-11","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-09-27","order":2,"name":"published","label":"Published online","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-02-01","order":3,"name":"published","label":"Print publication","group":{"name":"publication_history","label":"Publication History"}}]}}
