The present invention is a method for locating a sensor (38) over an underlying artery having a blood pulse. The sensor (38) is positioned at a plurality of locations above a known approximate location of the artery while applying a hold down pressure to the artery. Waveform pressure data are sensed at each one of the plurality of locations. The sensor (38) is positioned over the underlying artery based upon the sensed waveform pressure data at each one of the plurality of locations.

L'invention concerne une méthode permettant de positionner un capteur (38) sur le pouls d'une artère sous-jacente. Le capteur (38) est placé à plusieurs emplacements correspondant à une estimation approximative de la position de l'artère alors qu'au même moment une pression de retenue est appliquée sur l'artère. Les données des signaux de pression de retenue sont captées pour chaque emplacement. Le capteur (38) est placé au-dessus de l'artère sous-jacente en fonction des données des signaux de pression recueillies à chaque emplacement.
