Contrary to this established paradigm, this case\nreports on a 26-year-old, well-trained combat swimmer who succumbed to acute IPE during static immersion in temperate\n(21\u00b0C) water, while using a front-mounted counterlung rebreather. The incident occurred during repeated depth-controlled\nascent practice at the French military diving school. It was discovered that the diver had attempted to stop any gas leakage\ninto the system by over-tightening the automatic diluent valve (ADV) (25th notch of 27) during the dive, thus causing a\nhigh resistance to inspiratory flow. The ventilatory constraints imposed by this ADV setting were assessed as a 3.2 Joules\u2219L-1\ninspiratory work of breathing and -5 kPa (-50 mbar) transpulmonary pressure. This report confirms the key role of negative\npressure breathing in the development of interstitial pulmonary oedema. Such a breathing pattern can cause a lowering of\nthoracic, airway and interstitial lung pressure, leading to high capillary pressure during each inspiration. Repetition of the\ndiving drills resulted in an accumulation of interstitial lung water extravasation, causing pathological decompensation and\nproven symptoms.<\/jats:p>","DOI":"10.28920\/dhm48.1.40-44","type":"journal-article","created":{"date-parts":[[2018,3,12]],"date-time":"2018-03-12T21:29:16Z","timestamp":1520890156000},"page":"40-44","source":"Crossref","is-referenced-by-count":13,"title":["Immersion pulmonary oedema in a healthy diver not exposed to cold or strenuous exercise"],"prefix":"10.28920","volume":"48","author":[{"name":"Underwater Research Team (ERRSO), Military biomedical research institute (IRBA), Toulon, France","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olivier","family":"Castagna","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Universit\u00e9 de Toulon, LAMHESS (EA 6312), Toulon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S\u00e9bastien","family":"de Maistre","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of hyperbaric medicine, HIA St Anne military hospital, Toulon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bruno","family":"Schmid","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Underwater Research Team (ERRSO), Military biomedical research institute (IRBA), Toulon, France","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Delphine","family":"Caudal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of radiology, HIA St Anne military hospital, Toulon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacques","family":"Regnard","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"University Hospital, EA3920 University Bourgogne Franche-Comt\u00e9, Besan\u00e7on, France","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"11463","published-online":{"date-parts":[[2018,3,31]]},"container-title":["Diving and Hyperbaric Medicine Journal"],"original-title":[],"deposited":{"date-parts":[[2025,9,8]],"date-time":"2025-09-08T02:41:44Z","timestamp":1757299304000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.dhmjournal.com\/images\/IndividArticles\/48March\/Castagna_dhm48140-44.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,3,31]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2018,3,31]]}},"URL":"https:\/\/doi.org\/10.28920\/dhm48.1.40-44","relation":{},"ISSN":["2209-1491"],"issn-type":[{"value":"2209-1491","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,3,31]]}}}
