APPARATUS AND METHOD FOR GENERATING A CONDITION INDICATION

摘要

An apparatus for generating a condition indication using a time sequence of data values, each data value representing a physiological measure of a condition of a subject at a time, comprises: a transformer (132) for transforming the time sequence of data values into a transformed sequence of data values using a transform rule, wherein the transform rule is such that a certain characteristic in a time course of the physiological measure is represented by the transformed sequence of data values is more linear than the time course before the transform; a rate of change calculator (135) for calculating an estimated rate of change for the transformed sequence of data values; and a processor (137) for processing the estimated rate of change to output the condition indication.
