1. A computer-implemented method for monitoring cough in a subject comprising:

  • monitoring data comprising tidal volume data and sound data with a monitoring device responsive to said subject;

    processing said monitored tidal volume (VT) data in order to recognize a respiratory event when a peak-to-peak amplitude of a breath exceeds a threshold;

    processing said monitored sound data in order to recognize a sound event when a sound envelope exceeds a threshold;

    processing each recognized event respiratory to determine if it temporally overlaps a sound event and further to determine if it has an expiration-inspiration pattern characteristic of a cough; and

    selecting as a cough event each respiratory event that overlaps a sound event and that has said characteristic expiration-inspiration pattern.
