Abstract: Medical apparatus (20) includes an auscultation pickup unit (26) configured to sense acoustic waves emitted from a body of a subject (24) and to output signals in response thereto. Processing circuitry (40, 42, 44, 50) is configured to collect the signals output while the auscultation pickup unit contacts multiple locations on the body of the subject, including a respective signal acquired at each contacted location, to extract from each of the signals features of breath sounds of the subject, to compute multiple local scores including a respective local score for each contacted location based on the features extracted from the respective signal, and to classify a respiratory condition of the subject by combining the multiple local scores.

Abstract: A medical device (20) includes a case (26) of a size and shape suitable to be held in a hand (24) of a subject (22). An acoustic transducer (36) is disposed in the case and configured to output an acoustical signal in response to acoustic waves that are emitted from a thorax of the subject and received through the front surface of the case when the subject holds the case against the thorax. One or more sensors (46, 48, 50) are disposed on the case and configured to acquire one or more physiological signals from one or more fingers (30) of the subject while the subject holds the case in the hand. Processing circuitry (40) is contained in the case and coupled to receive and process the acoustical signal and the one or more physiological signals and to output data indicative of a medical condition of the subject.
