Method and apparatus for monitoring heart failure patients with cardiopulmonary comorbidities

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, and adapted to detect low FVC if the pulmonary edema detector does not indicate a detection of the cardiogenic edema, the low FVC detector including a comparator having an output indicating a detection of the low FVC when the FVC parameter is below a predetermined threshold FVC parameter value;
• 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.
