The dog was anesthetized and underwent advanced imaging, the findings of which suggested that the trachea was intact. However, when the cuff of the endotracheal tube was deflated during the dog\u2019s recovery from anesthesia, sudden oxygen desaturation occurred. Given no radiographic signs of deteriorating lung injury, a tracheal tear was suspected. For rapid confirmation of a tracheal tear, without the need for additional advanced imaging, the oxygen concentration at the skin wound was investigated by use of an oxygen analyzer. When the dog was breathing 100% oxygen, the analyzer identified a higher oxygen concentration at the edge of the penetrating wound, compared with the concentration of oxygen in room air; the leakage of oxygen-rich gases from the airway through the wound confirmed the presence of a tracheal tear, immediately indicating the need for surgical exploration and repair.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s003\">\n<jats:title>TREATMENT AND OUTCOME<\/jats:title>\n<jats:p>Surgical repair of the tracheal tear with a left sternothyroideus muscle flap was successfully performed.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s004\">\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>For this dog, an oxygen analyzer was used to confirm the presence of a tracheal tear, suggesting that application of an oxygen analyzer may be useful in the emergency management of neck trauma cases.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/javma.259.8.880","type":"journal-article","created":{"date-parts":[[2021,10,5]],"date-time":"2021-10-05T14:08:36Z","timestamp":1633442916000},"page":"880-884","source":"Crossref","is-referenced-by-count":2,"title":["Diagnosis of a tracheal tear by use of an oxygen analyzer in a dog with cervical trauma"],"prefix":"10.2460","volume":"259","author":[{"given":"Kate L.","family":"Walters","sequence":"first","affiliation":[{"name":"From the Department of Veterinary Medicine, University of Cambridge, Cambridge, CB3 0ES, England."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebekah C.","family":"Knight","sequence":"additional","affiliation":[{"name":"From the Department of Veterinary Medicine, University of Cambridge, Cambridge, CB3 0ES, England."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"key":"R1","series-title":"J Vet Med A Physiol Pathol Clin Med","doi-asserted-by":"publisher","first-page":"107","DOI":"10.1046\/j.1439-0442.2002.jv416.x","article-title":"Dog bite wounds in dogs and cats: a retrospective study of 196 cases","volume":"49","author":"Shamir MH","year":"2002","unstructured":"Shamir MH, Leisner S, Klement E,  Dog bite wounds in dogs and cats: a retrospective study of 196 cases.
