Abstract: A non-invasive device for determining the hemodynamic state of a subject. The device comprises: (a) at least two electrodes (20); (b) an electrical total body integral bioimpedance measuring unit (26) coupled to the electrodes; and (c) a data processing and analyzing unit (30) coupled to the electrical integral bioimpedance measuring unit and optionally to a display means (34) for calculating the cardiac output of the subject from the active component of the-integral bioimpedance. Also disclosed are methods for determining the hemodynamic state of a subject and for diagnosing a tendency of a subject to a cardiac disease.

Abstract: 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.
