1. A system for respiration or cardiac condition characterization and abnormality detection, comprising:

  • an interface for receiving data representing a signal indicating concentration of carbon dioxide in patient gases over a plurality of signal cycles;

    a signal processor for using the received data in determining a plurality of amplitude related characteristic values comprising at least two of,(a) a magnitude of an amplitude of a baseline of said signal,(b) a magnitude of an amplitude at an end of early exhalation of said signal,(c) a magnitude of an amplitude of a start of the exhalation plateau of said signal,(d) a magnitude of an amplitude of an end tidal point of said signal and(e) a magnitude of an amplitude at an end of inhalation point of said signal;

    a comparator for comparing at least one of said amplitude related characteristic values or a value derived from said amplitude related characteristic values, with a threshold value to provide a comparison indicator; and

    a patient monitor for in response to said comparison indicator indicating an amplitude related characteristic value or a value derived from said amplitude related characteristic values, exceeds the threshold value, generating an alert message associated with the threshold.
