Brief Summary
Reducing the risk of perioperative cardiovascular complications is a major issue for anesthesiology practice and research. Carotid-Femoral Pulse Wave Velocity (PWVcf)is a predictive, early and independent biomarker of cardiovascular events. Despite the unanimous support for PWVcf, it has not been widely used in routine clinical practice because of the complexity of the measurement method. Our team has developed a method to estimate PWVcf continuously in the operating room from the data obtained by the usual monitoring: an electrocardiogram (ECG), a digital photoplethysmography (PPG) and an oscillometric brachial sphygmomanometer for non-invasive blood pressure measurement (NIP). The objective of this study is to validate, during anesthesia, the method of estimation of PWV (obtained using the usual monitoring tools including the parameters derived from the SpO2 signal, NIBP and ECG) by comparing it to the reference method by measuring the carotid-femoral transit time obtained by Doppler effect. The measurement of the carotid-femoral transit time obtained by Doppler effect is totally non-invasive.

Interventions
* Measurement of the carotid-femoral transit time (ms) (recorded on Data Warehouse Connect). * Measurement of the distance between the carotid and femoral points with a tape measure (m). * Calculation of the propagation speed of the wave PWV (expressed in m/s). For all patients PWV in (m/s=) will be collected over three distinct periods: * Before induction (awake without premedication) * During general anesthesia or loco-regional anesthesia * Upon awakening from general anesthesia or lifting of the loco-regional anaesthesia
