The area under the curve, sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of the two techniques at 95% confidence interval was 0.613, 30.4%, 93.3%, 58.3%, 81.4%, 73.6% for IVC-CI and 0.853, 83.3%, 80.3%, 57.1%, 93.8%, 77.4% for LVOT -VTI, respectively. In multivariate analysis, the cutoff value for IVC-CI was &gt;51.5 and for LVOT-VTI it was \u226417.45 for predicting PIH with odd ratio [OR] of 8.491 (P=0.025) for IVCCI and OR of 17.427 (P&lt;0.001) for LVOT. LVOT-VTI assessment was possible in all the patients, while 10% of patients were having poor window for IVC measurements.Conclusions: We recommend the use of POCUS using LVOT-VTI or IVC-CI to predict PIH, to decrease the morbidity of patients undergoing surgery. Out of these, we recommend LVOT-VTI measurements as it has showed a better diagnostic accuracy (77.4%) with no failure rate.<\/jats:p>","DOI":"10.4266\/acc.2023.00913","type":"journal-article","created":{"date-parts":[[2024,2,23]],"date-time":"2024-02-23T02:12:01Z","timestamp":1708654321000},"page":"117-126","update-policy":"https:\/\/doi.org\/10.4266\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Diagnostic
