Method for determining hemodynamic state

An apparatus for determining the hemodynamic state of a subject, comprising:

• (a) means for 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 hemodynamic state selected from the group consisting of systolic congestive heart failure (sCHF), pulmonary edema (PE), cardiogenic shock (CS), vasodilative shock (VS) and normal state;
• (b) means for determining the range of Cpi and SVRi paired values corresponding to each of said hemodynamic states;
• (c) means for determining the Cpi and SVRi paired value of said subject;
• (d) means for comparing the Cpi and SVRi paired value of said subject to the ranges of Cpi and SVRi paired values determined by the means of (b);
• and
• (e) means for determining the range of Cpi and SVRi paired values which is most similar to the Cpi and SVRi paired value of said subject, the hemodynamic state corresponding to said range indicating the hemodynamic state of said subject.
