APPARATUS AND METHOD FOR GENERATING A CONDITION INDICATION
First Claim
1. 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, comprising:
- a transformer 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 for calculating an estimated rate of change for the transformed sequence of data values; and
a processor for processing the estimated rate of change to output the condition indication.
