This patent document discusses systems, devices, and methods for increasing a sensitivity or specificity of thoracic fluid detection in a subject and differentiating between pleural effusion and pulmonary edema. In one example, a thoracic impedance measurement circuit senses a thoracic impedance signal....http://www.google.fr/patents/US7340296?utm_source=gb-gplus-shareBrevet US7340296 - Detection of pleural effusion using transthoracic impedance
