Non-invasive and Continuous Detection of Arterial Hypotension Using Photoplethysmographic Signal During Induction of Anaesthesia: Proof of Concept0
Last Updated

0Study summary
During general anaesthesia, intraoperative hypotension (IOH), defined as a mean arterial pressure (MAP) drop of more than 20%, is frequent with potential deleterious effects for patients. Pulse oximeter is mandatory in the operating room making photoplethysmographic (PPG) signal and parameters such as the relative dicrotic notch height (Dicpleth) or the perfusion index (PI) readily available. The purpose of this study is to investigate whether Dicpleth and PI could detect IOH during anaesthesia induction and follow their variations during vasopressor boluses.
