1. A system for determining pulmonary performance from transthoracic impedance measures, comprising:

  • a correlation component to correlate transthoracic impedance measures collected by an implantable medical device to pulmonary functional measures;

    an arrangement component to group the pulmonary functional measures by respiratory pattern; and

    an evaluation component to evaluate pulmonary performance, comprising;

    an analysis subcomponent to determine differences by comparing the pulmonary functional measures for each respiratory pattern to the pulmonary functional measures for at least one previous respiratory pattern;

    an identification module to identify a trend from the differences; and

    an alert subcomponent to generate an alert upon sufficient deviation of the trend from a threshold criteria.
