Detection of pleural effusion using transthoracic impedance

摘要: This patent document discusses systems, devices, and methods for increasing a sensitivity or specificity of thoracic fluid detection in subject differentiating between pleural effusion pulmonary edema. In one example, impedance measurement circuit senses signal. another processor receives the signal determines whether such is “significant.” A significant indicates presence may be recognized by comparing (or variation thereof) to threshold. When recognized, adapted detect both of: indication edema using combination physiologic information, patient symptom posture information. threshold adjusted physiologic, symptom,
