1. A system for detecting cardiopulmonary conditions, comprising:

  • a parameter input to receive parameters indicative of a plurality of cardiopulmonary conditions, the parameters including a forced vital capacity (FVC) parameter, a forced expiratory volume (FEV) parameter, and one or more edema-indicating parameters indicative of cardiogenic pulmonary edema;

    a pulmonary edema detector coupled to the parameter input, the pulmonary edema detector adapted to detect the cardiogenic pulmonary edema based on the one or more edema-indicating parameters;

    a low FVC detector coupled to the pulmonary edema detector, the low FVC detector adapted to detect a low FVC when the FVC parameter is below a predetermined threshold FVC parameter value if the cardiogenic pulmonary edema is not detected; and

    a pulmonary condition detector coupled to the low FVC detector, the pulmonary condition detector adapted to detect at least an obstructive pulmonary disease and a restrictive pulmonary disease based on the FVC parameter and the FEV parameter if the low FVC is detected.
