The present invention concerns an automatic method, as well as the related system and the tools allowing the same to be executed, for measuring and processing blood pressure starting from a detected pressure signal, the method operating in the time domain for discriminating whether the detected signal is an adequate measurement or not and, where it is not, time domain analysis automatically selects a low-pass filter to, possibly iteratively, apply to the detected pressure signal for having correct values and wave form of the blood pressure.L'invention concerne un procédé, un système et des moyens automatisés permettant de traiter la pression artérielle à partir d'un signal de pression détecté, ce procédé s'effectuant dans le domaine temporel afin de déterminer une valeur (RES) reliée au rendement énergétique du système biologique surveillé.
