The purpose of this report is to evaluate techniques for end\u2010expiratory breath\u2010holding applicable to a pulmonary\u2010compromised population. Eighty\u2010seven consecutive outpatients with chronic pulmonary diseases and 31 healthy nonsmoking volunteers were recruited for the study. All subjects were asked to hold their breath in end\u2010expiration while in the supine position (29 after breathing room air, 29 after hyperventilating room air for six breaths, and 29 after breathing O<jats:sub>2<\/jats:sub> from a portable oxygen tank via nasal cannula until pulse\u2010oximeter readings stabilized or reached 100%). Each volunteer was tested with all three methods. The mean length of time for a breath\u2010hold on room air without hyperventilation was 9.2 seconds for the patients and 31.7 seconds for the volunteers. A breath\u2010hold after hyperventilation of room air was timed at 12.3 seconds for the patients and 41.2 seconds for the volunteers, and after O<jats:sub>2<\/jats:sub> administration, the breath\u2010hold was 22.4 seconds for the patients and 60.9 seconds for the volunteers. No adverse effects occurred. The pulmonary\u2010compromised patient can suspend respiration most successfully after O<jats:sub>2<\/jats:sub> administration (<jats:italic>P<\/jats:italic> &lt; .0001), whereas hyperventilation seems to be less beneficial. Nonpulmonary\u2010compromised volunteers can hold their breath for longer periods of time.<\/jats:p>","DOI":"10.1002\/jmri.1880070323","type":"journal-article","created":{"date-parts":[[2007,3,15]],"date-time":"2007-03-15T20:34:44Z","timestamp":1173990884000},"page":"595-597","source":"Crossref","is-referenced-by-count":68,"title":["Breath\u2010holding in healthy and pulmonary\u2010compromised populations: Effects of hyperventilation and oxygen inspiration"],"prefix":"10.1002","volume":"7","author":[{"given":"Burton","family":"Marks","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donald G.","family":"Mitchell","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John P.","family":"Simelaro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,11,17]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"1","volume-title":"Computed tomography of the pancreas","author":"Donovan PJ","year":"1983"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/00004424-199409000-00009"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01888585"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/00004728-198707000-00043"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/0034-5687(87)90017-X"},{"key":"e_1_2_1_7_2","first-page":"626","article-title":"Bradycardia during human diving","volume":"49","author":"Landsberg PG","year":"1975","journal-title":"S Afr Med J"},{"key":"e_1_2_1_8_2","first-page":"305","article-title":"Supraventricular arrhythmias following breath\u2010hold submersions in cold water","volume":"21","author":"Tipton MJ","year":"1994","journal-title":"Undersea Hyperb Med"},{"key":"e_1_2_1_9_2","first-page":"1","article-title":"Cardiovascular and pulmonary responses to breath\u2010hold diving in humans","volume":"620","author":"Liner MH","year":"1994","journal-title":"Acta Physiol Scand Suppl"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/0034-5687(87)90091-0"},{"key":"e_1_2_1_11_2","first-page":"1069","volume-title":"Textbook of respiratory medicine","author":"Snider G","year":"1982"},{"key":"e_1_2_1_12_2","first-page":"361","article-title":"Breath\u2010hold duration in man and the diving response induced by face immersion:","volume":"15","author":"Sterba JA","year":"1988","journal-title":"Undersea Biomed Res"}],"container-title":["Journal of Magnetic Resonance Imaging"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fjmri.1880070323","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jmri.1880070323","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,28]],"date-time":"2023-10-28T12:15:30Z","timestamp":1698495330000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/jmri.1880070323"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1997,5]]},"references-count":11,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1997,5]]}},"alternative-id":["10.1002\/jmri.1880070323"],"URL":"https:\/\/doi.org\/10.1002\/jmri.1880070323","archive":["Portico"],"relation":{},"ISSN":["1053-1807","1522-2586"],"issn-type":[{"value":"1053-1807","type":"print"},{"value":"1522-2586","type":"electronic"}],"subject":[],"published":{"date-parts":[[1997,5]]}}}
