Abstract:
1. A system, comprising: an implantable housing; a sensor adapted for ambulatory operation in a patient and adapted to be positioned adjacent to a pulmonary system of the patient, the sensor adapted to output signals indicative of lung sounds; filtering circuitry provided at the housing and adapted to filter the sensor output signals by removing signal content unrelated to adventitious lung sounds; detection circuitry provided at the housing and adapted to receive filtered sensor output signals from the filtering circuitry, the detection circuitry further adapted to detect presence of adventitious lung sounds based on a comparison between the filtered sensor output signals and criteria indicative of adventitious lung sounds; a memory provided at the housing and configured to store at least data indicative of adventitious lung sounds detected by the detection circuitry; and a processor provided at the housing and coupled to the detection circuitry and the memory, the processor configured to organize the adventitious lung sounds data as log entries in the memory.
