A cough heard in patients with bronchiectasis or bronchitis. It may be provoked by a change of posture, as when getting up in the morning, and produces frothy mucus that is copious, dirty gray, and has a fetid odor. The cough is hacking and irritating in the earlier stages; in later stages it is looser and easier. Cold air can exacerbate this cough.
