Medical device with acoustic sensor

A medical system comprising:

• a server;
• and
• a medical device comprising:
• a first network interface;
• at least one electrocardiogram (ECG) electrode configured to sense cardiac activity of a patient;
• at least one acoustic sensor configured to detect one or more sounds indicative of a state of health of the patient;
• at least one motion sensor configured to detect motion of the patient;
• and
• at least one processor coupled with the at least one acoustic sensor, the at least one ECG electrode, and the at least one motion sensor and configured to
• receive at least one ECG signal corresponding to the sensed cardiac activity of the patient from the at least one ECG electrode,
• receive at least one acoustic signal corresponding to the one or more sounds indicative of the state of health of the patient from the at least one acoustic sensor,
• receive at least one motion signal corresponding to the motion of the patient from the at least one motion sensor, and
• transmit the at least one acoustic signal, the at least one ECG signal, and the at least one motion signal to the server via the first network interface for identification of sleep apnea in the patient based on analysis of the at least one acoustic signal, the at least one ECG signal, and the at least one motion signal, wherein the analysis includes an analysis of at least a strength of an S3 sound from the at least one acoustic signal;
• wherein the server comprises a second network interface configured to receive the at least one acoustic signal, the at least one ECG signal, and the at least one motion signal from the medical device.

A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor, cause the processor to perform a method to identify sleep apnea in a patient, the method comprising:

• receiving at least one acoustic signal corresponding to one or more sounds indicative of a state of health of the patient from at least one acoustic sensor coupled to a garment worn by the patient;
• receiving at least one ECG signal corresponding to a sensed cardiac activity of the patient from at least one ECG electrode coupled to the garment worn by the patient;
• receiving at least one motion signal corresponding to a motion of the patient from at least one motion sensor coupled to the garment worn by the patient;
• and
• transmitting the at least one acoustic signal, the at least one ECG signal, and the at least one motion signal to a remote system for identification of sleep apnea in the patient based on analysis of the at least one acoustic signal, the at least one ECG signal, and the at least one motion signal, wherein the analysis includes an analysis of at least a strength of an S3 sound from the at least one acoustic signal.
