Abstract

A system and method for patient monitoring using a reference baseline for use in automated patient is described. One or more reference physiological measures relating to individual patient information recorded during an initial observation period are processed into a reference baseline. One or more updated physiological measures recorded subsequent to the initial observation period are periodically received. The updated physiological measures are compared to the reference physiological measures in the reference baseline to generate a patient status indicator identifying any such substantially non-conforming updated physiological measure.
