Claim:
1. A method for determining a cardiovascular performance reserve for an individual using a medical system that includes at least one data source and a computerized analysis unit in communication with the at least one data source, the computerized analysis unit employing a processor and a memory, comprising the steps of: a. receiving, by the analysis unit from the at least one data source, input physiological data from the individual for obtaining a parameter Z which is or approximates the product of the Stroke Volume (SV) by the Systemic Vascular Resistance (SVR); b. providing a value, to the analysis unit from the at least one data source, representing the Respiratory Rate (RR) of said individual; c. providing anthropometric data, to the analysis unit from the at least one data source, of said individual for calculating the Body Surface Area (BSA) of said individual; d. processing, by the analysis unit, the input physiological data signals to provide a normalized Cardiovascular Reserve Index (CVRI) by using said Z parameter, said RR and said BSA, according to the following formula: e. outputting said CVRI and estimating the individual's medical condition therefrom; and f. outputting a notification of cardiovascular status of the individual based on the CVRI, and prioritizing medical assistance or triage for the individual based on the cardiovascular status notification indicating a heart failure and/or shock condition over other individuals awaiting medical assistance or triage.
