Abstract

A system includes a sensor configured to sense first and second physiological signals produced by a source; and a processing device communicatively coupled to the sensor. The processing device is configured to: receive the first and second physiological signals; determine a first value of a signal characteristic; determine a second value of the signal characteristic; access a scaling map having scaling vectors, and each scaling vector having at least one signal characteristic correction value; determine a scaled first value and a scaled second value based on a first scaling vector and a second scaling vector, respectively; and predict a physiological event based on the scaled first value of the signal characteristic and the scaled second value of the signal characteristic.
