Worldwide, each year, more than 300 million surgical procedures are performed worldwide. Arterial hypotension is among the most frequent critical event that may occur during a surgical procedure. This arterial hypotension may be responsible for postoperative morbidity and mortality. The pathogenesis of arterial hypotension is sometime complex and progressive. An AI solution as been developed to help anesthesiologists identifying clinical situations at high risk of subsequent arterial hypotension. This solution is based on arterial pulse pressure analysis. The prediction of a potential arterial hypotension offers the clinician an early window of opportunity to act and optimize the patient’s hemodynamic status.
