The present invention is a method and apparatus (20) for calculating blood pressure of an artery having a pulse. The method includes applying a varying pressure to the artery. Pressure waveforms (450) are sensed to produce pressure waveform data. Waveform parameters (510, 530) are derived from the sensed pressure waveform data. Blood pressure is then determined using the derived parameters.

L'invention se rapporte à un procédé et appareil (20) destinés à calculer la tension artérielle à partir du pouls d'une artère. Le procédé consiste à appliquer une pression variable à l'artère. Des courbes de pression (450) sont détectées afin de générer des données de signaux de pression. Des paramètres de signaux (510, 530) sont dérivés à partir des données des signaux de pression qui ont été captés. La tension artérielle s'obtient au moyen des paramètres dérivés.
