ABSTRACT:
A therapeutic system provides a clinician with an appropriate course of treatment for a patient whose cardiovascular system is operating outside the normal range of values for the left cardiac work index (LCWI) and the systemic vascular resistance index (SVRI). The left cardiac work index and the systemic vascular resistance index are calculated from the cardiac index (CI) and mean arterial blood pressure (MAP) and are displayed as relative values so that the clinician can readily determine which of the vascular parameters are outside the normal range. Preferably, the cardiac index and the other cardiac parameters are measured by an electrical bioimpedance monitor that provides continuous dynamic measurement of the parameters. The left cardiac work index and the systemic vascular resistance index are calculated by a personal computer that displays the calculated parameters in an easily discernible manner.
