Peripheral vascular tone can be monitored as a perfusion index (PI) from a pulse oximeter.

In the PI &gt;3.5 group, 46 (97.9%) females had hypotension and required a high volume of IV fluids, and 29 (61.7%) required vasopressors, and the association with PI was statistically significant with Pearson\u2019s Chi-square values of 32.26 and 32.36, respectively (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.001).

We established baseline PI &gt;2.9 can predict post-spinal hypotension with high sensitivity and specificity. PI is simple, quick, and non-invasive and can be used as a predictor for post-spinal hypotension in parturients undergoing LSCS so that prophylactic measures can be considered in at-risk patients for better maternal and fetal outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/joacp.joacp_178_22","type":"journal-article","created":{"date-parts":[[2023,5,11]],"date-time":"2023-05-11T22:01:23Z","timestamp":1683842483000},"page":"37-42","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":7,"title":["Perfusion index to predict post spinal hypotension in lower segment caesarean section"],"prefix":"10.4103","volume":"40","author":[{"given":"Minal J.","family":"Harde","sequence":"first","affiliation":[{"name":"Department of Anaesthesiology, Topiwala National Medical College & B.Y.L.
