1. An active implantable medical device, comprising:

  • means for collecting a transthoracic impedance signal representing instantaneous lung volume variations from a patient; and

    spirometric means for producing, from the transthoracic impedance signal received over at least one respiratory cycle, data pairs comprisinga lung volume (V), anda pulmonary flow (dV/dt), represented by the derivative of said lung volume, wherein said data pairs represent a spirometric characteristic (S) corresponding to the pulmonary flow (dV/dt) relative to the lung volume.
