A method for determining the hemodynamic state of a subject. The method comprises (a) determining the cardiac power index (Cpi) and systemic vascular resistance index (SVRi) values of a plurality of patients who have been diagnosed as having a specified hemodynamic state; (b) determining the range of Cpi and SVRi paired values corresponding to each of the hemodynamic states; (c) determining the Cpi and SVRi paired value of the subject; (d) comparing the Cpi and SVRi paired value of the subject to the ranges of Cpi and SVRi paired values determined in step (b); and (e) determining the range of Cpi and SVRi paired values which is most similar to the Cpi and SVRi paired value of the subject. The hemodynamic state which corresponds to the range indicates the hemodynamic state of the subject.

L'invention concerne un procédé qui permet de déterminer l'état hémodynamique d'un sujet. Le procédé consiste à: a) déterminer les valeurs de l'indice de fréquence cardiaque (Cpi) et de l'indice de de résistance vasculaire systémique (SVRi) de plusieurs patients dont un diagnostic établit qu'ils présentent un état hémodynamique déterminé; b) déterminer la série des valeurs Cpi et SVRi appariées correspondant à chacun des états hémodynamiques; c) déterminer la valeur Cpi et SVRi appariée du sujet; d) comparer la valeur Cpi et SVRi appariée du sujet avec les séries de valeurs Cpi et SVRi appariées déterminées à l'étape b); et e) déterminer la série des valeurs Cpi et SVRi appariées les plus similaires à la valeur Cpi et SVRi appariée du sujet. L'état hémodynamique correspondant à cette série est indicatif de l'état hémodynamique du sujet.
