Pigs were subjected to maneuvers to alter MAP. Paired values for invasive and noninvasive MAP (iMAP and NiMAP) were recorded every 2 minutes. Bland-Altman plots with bias, limits of agreement, and percentage error were constructed using each pair and the average of 5 consecutive values. Concordance was calculated using changes in MAP at 20-minute intervals. Receiver operating characteristics (ROC) curves were constructed to test NiMAP for detection of hypotension (&lt; 70 mm Hg) and hypertension (\u2265 120 mm Hg).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a3\">\n<jats:title>RESULTS<\/jats:title>\n<jats:p>Bias of NiMAP was \u22128.59 mm Hg for consecutive pairs and \u22128.85 mm Hg for averaged pairs, relative to iMAP. Limits of agreement and percentage error were reduced for averages (19%) over individual pairs (26%). Concordance was 82%. The area under the ROC curve for detecting hypotension with NiMAP was 0.936, with a best cutoff value of 63 mm Hg NiMAP. The area under the ROC curve for hypertension was 0.940, with a best cutoff value of 101 mm Hg NiMAP.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a4\">\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>Averaging several consecutive values improves the accuracy of NiMAP measurements.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a5\">\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>This device correctly tracked changes in MAP approximately 80% of the time and appears reliable for diagnosing arterial hypotension.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/ajvr.24.05.0145","type":"journal-article","created":{"date-parts":[[2024,10,3]],"date-time":"2024-10-03T14:48:12Z","timestamp":1727966892000},"source":"Crossref","is-referenced-by-count":0,"title":["Accuracy of oscillometric blood pressure measurement using a Cardell Touch multiparameter monitor in anesthetized pigs"],"prefix":"10.2460","volume":"85","author":[{"given":"Stephanie","family":"Zeitouneh","sequence":"first","affiliation":[{"name":"College of Veterinary Medicine, Cornell University, Ithaca, NY"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joaquin","family":"Araos","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences, College of Veterinary Medicine, Cornell University, Ithaca, NY"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2014-9040","authenticated-orcid":true,"given":"Manuel","family":"Martin-Flores","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences, College of Veterinary Medicine, Cornell University, Ithaca, NY"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"issue":"4","key":"B1","series-title":"Lab Anim Sci","first-page":"383","article-title":"Swine as replacements for dogs in the surgical teaching and research laboratory","volume":"34","author":"Swindle MM","year":"1984","unstructured":"Swindle MM.
