Assuming that peripheral blood flow obstruction by the artery occlusion test (AOT) or venous occlusion test (VOT) increases the CRT, the cut-off value for peripheral circulatory failure was studied by performing a comparative analysis with CRT with no occlusion test (No OT).<\/jats:p><\/jats:sec><jats:sec id=\"S1049023X23005812_as3\"><jats:title>Methods:<\/jats:title><jats:p>Fourteen (14) healthy adults (age: 20\u201326 years) participated in the study. For the vascular occlusion test, a sphygmomanometer was placed on the left upper arm of the participant in the supine position, and a pressure of 30mmHg higher than the systolic pressure was applied for AOT, a pressure of 60mmHg was applied for VOT, respectively, and no pressure was applied for No OT. The CRT was measured from the index finger of the participant\u2019s left hand.<\/jats:p><\/jats:sec><jats:sec id=\"S1049023X23005812_as4\"><jats:title>Results:<\/jats:title><jats:p>Experimental results revealed that CRT was significantly longer in the AOT and did not differ significantly in the VOT. The cut-off value for peripheral circulatory failure was found to be 2.88 seconds based on Youden\u2019s index by using receiver operating characteristic (ROC) analysis with AOT as positive and No OT as negative.<\/jats:p><\/jats:sec><jats:sec id=\"S1049023X23005812_as5\"><jats:title>Conclusion:<\/jats:title><jats:p>Significant results were obtained in a previous study on the evaluation of septic shock patients when CRT &gt; three seconds was considered abnormal, and the cut-off value for peripheral circulatory failure in the current study validated this.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s1049023x23005812","type":"journal-article","created":{"date-parts":[[2023,6,5]],"date-time":"2023-06-05T09:11:02Z","timestamp":1685956262000},"page":"319-325","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":2,"title":["Cut-Off Value of Capillary Refill Time for Peripheral Circulatory Failure Diagnosis"],"prefix":"10.1017","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4433-4144","authenticated-orcid":false,"given":"Masayoshi","family":"Shinozaki","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taka-aki","family":"Nakada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daiki","family":"Saito","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keisuke","family":"Tomita","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yukihiro","family":"Nomura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiya","family":"Nakaguchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2023,6,5]]},"reference":[{"key":"S1049023X23005812_ref16","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0188548"},{"key":"S1049023X23005812_ref2","doi-asserted-by":"publisher","DOI":"10.1186\/s13054-018-2295-3"},{"key":"S1049023X23005812_ref18","doi-asserted-by":"publisher","DOI":"10.1007\/s00134-014-3326-4"},{"key":"S1049023X23005812_ref19","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2019.0071"},{"key":"S1049023X23005812_ref12","unstructured":"12.
