Predictive weighting of hypotension profiling parameters

A method for use by a system for monitoring health of a living subject, the system comprising a hemodynamic sensor, a sensory alarm, and a hardware unit including a hardware processor, an analog-to-digital converter (ADC), and a hypotension prediction software code including a predictive weighting module stored in a system memory, the method comprising:

• obtaining, by the hypotension prediction software code executed by the hardware processor, a digital hemodynamic data converted, by the ADC, from a signal received from the hemodynamic sensor;
• obtaining, by the hypotension prediction software code executed by the hardware processor, one or more vital sign parameters characterizing vital sign data from the digital hemodynamic data;
• deriving, by the hypotension prediction software code executed by the hardware processor, differential parameters based on the one or more vital sign parameters characterizing vital sign data;
• generating, by the hypotension prediction software code executed by the hardware processor, combinatorial parameters using the one or more vital sign parameters characterizing vital sign data and the differential parameters;
• determining, by the hypotension prediction software code using the predictive weighting module and executed by the hardware processor, a risk score corresponding to the probability of a future hypotension event for the living subject based on a weighted combination of a plurality of hypotension profiling parameters including the one or more vital sign parameters characterizing vital sign data, the differential parameters and the combinatorial parameters;
• and
• invoking, by the hypotension prediction software code executed by the hardware processor, the sensory alarm if the risk score satisfies a predetermined risk criterion.
