First Claim
Patent Images
1. A method comprising:
- receiving an acoustic signal from an acoustic sensor implanted in a patient;
receiving a patient activity signal from an activity sensor implanted in the patient;
analyzing the acoustic signal in combination with the patient activity signal; and
determining whether a cough has occurred based on the analysis of the acoustic signal in combination with the patient activity signal.

Abstract
The present disclosure is directed to the detection of coughs and coughing episodes using acoustic signals. In various examples, an implantable medical device processes an acoustic signal obtained from an acoustic sensor to determine whether a patient has coughed. In some examples, the implantable medical device also performs a cough severity assessment. In some examples, the cough severity assessment may include a determination of the depth of the cough, the duration of the coughing episode, or whether the cough was wet or dry.
