Abstract

L'invention concerne un système et un procédé non invasifs ou très peu invasifs d'évaluation des paramètres du système cardiovasculaire afin d'estimer le débit cardiaque et le volume sanguin circulatoire d'un patient sous hémodialyse. Des indicateurs intravasculaires sont stimulés, et des modèles d'émissions détectés en vue de calculer le débit cardiaque, l'index cardiaque, le volume sanguin et d'autres indicateurs de l'état de santé cardiovasculaire avant et pendant l'hémodialyse.
