During the study, four cases of nosocomial pneumonia occurred; two in the intervention group (13.3%) and two in the control group (11.8%) (\u03c72 = 0.018, p = 0.894). No patients died during the study period.<br \/>\nConclusion: No high quality evidence exists to assist nurses to make a decision about how frequently to change humidifier circuitry. Potential cost savings involved in extending the time frame between humidifier circuitry changes indicate that a large scale randomised controlled trial is both feasible and important.<\/p>\n<h2>Authors<\/h2>\n<ul>\n<li>Joan Webster<\/li>\n<li>Laurie Hall<\/li>\n<li>Di Goodwin<\/li>\n<li>Susan Bligh<\/li>\n<li>Fiona Coyer<\/li>\n<\/ul>\n<h2>Keywords<\/h2>\n<p>Oxygen inhalation therapy, humidity, pneumonia, humidifier circuitry<\/p>\n<h2>References<\/h2>\n<p>References not available for this article.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This article was originally published as: Three versus seven day circuit changes of humidified oxygen circuitry: a feasibility study Original&#8230;<\/p>\n","protected":false},"author":21,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[124],"tags":[5097,4294,3919,5096],"class_list":["post-7750","post","type-post","status-publish","format-standard","hentry","category-articles","tag-humidifier-circuitry","tag-humidity","tag-oxygen-inhalation-therapy","tag-pneumonia","wpcat-124-id"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.8 -
