The apparatus and methods of the present invention provide a non-invasive measurement of blood pressure with a frequency that approximates a continuous measurement. Blood pressure measurement provides information that is both clinically and diagnostically significant. In accordance with an aspect of the present invention, a method for providing a non-invasive measurement of blood pressure, includes obtaining a first input signal and a second input signal indicative of occlusive measurements of systolic blood pressure and diastolic blood pressure, respectively; tracking a signal indicative of pulse pressure; continuously measuring third signal indicative of mean blood pressure; and processing the signals to obtain a measurement indicative of systolic and diastolic blood pressure, wherein at least a portion of the measurement indicative of systolic and diastolic blood pressure is continuous. The second input signal indicative of diastolic blood pressure is analyzed to identify a maximum amplitude of the signal, the maximum amplitude being indicative of the diastolic blood pressure measurement.
L'invention concerne un appareil et des procédés pour mesurer, de manière non invasive, la tension artérielle à une fréquence se rapprochant d'une mesure en continu. La mesure de la tension artérielle permet d'obtenir des informations significatives sur le plan clinique et diagnostique. Un aspect de l'invention concerne un procédé pour réaliser une mesure non invasive de la tension artérielle, ledit procédé consistant à: obtenir un premier signal d'entrée et un deuxième signal d'entrée indiquant respectivement des mesures occlusives de la tension artérielle systolique et de la tension artérielle diastolique; effectuer un suivi d'un signal indiquant la tension différentielle; mesurer en continu un troisième signal indiquant une tension artérielle moyenne; et traiter les signaux pour obtenir une mesure indiquant la tension artérielle systolique et diastolique, au moins une partie de cette mesure étant continue. Le deuxième signal d'entrée indiquant la tension artérielle diastolique est analysé pour permettre d'identifier une amplitude maximale du signal, cette amplitude maximale indiquant la mesure de la tension artérielle diastolique.
