Abstract

L'invention concerne un procédé mis en oeuvre par ordinateur pour caractériser un volume sanguin circulant et des mécanismes compensatoires d'auto-régulation pour maintenir un volme sanguin circulant. Un signal biologique qui favorise l'onde de pouls artériel est recueilli à partir d'un capteur. Trois paramètres dérivés sont extrapolés à partir du signal biologique. Le premier paramètre, le stress circulatoire, reflète les changements de fréquence cardiaque. Le second, le volume sanguin circulant, reflète les changements d'intensité de fréquence de la fréquence cardiaque. Le troisième, l'indice de modification du volume de pouls (PVA) est un rapport de la somme des intensités des harmoniques de fréquence cardiaque sur l'intensité de la fréquence cardiaque du signal biologique non traité. Chaque paramètre est comparé à une valeur de seuil et évalué pour déterminer une justesse du volume sanguin circulant et une adéquation des mécanismes d'autorégulation utilisés pour conserver une justesse du volume sanguin circulant.
