Research progress on intraoperative blood pressure management guided by hypotension prediction index based on machine learning
Intraoperative hypotension is closely associated with postoperative poor prognosis.Machine learning hypotension predictive index(HPI)based on invasive and non-invasive blood pressure monitoring can predict hypotension in non-cardiac and cardiac surgery,which makes blood pressure manage-ment from passive processing to preventive active control.Hemodynamic management based on HPI reduces the occurrence of hypotension in surgery.In this artical,the introduction of HPI,the application of HPI in-vasive and non-invasive blood pressure monitoring in surgery,and the limitations of HPI are reviewed.
