My Mom has mild/medium
COPD. As a result she is very prone to bronchitis, which
in turn ushers in long periods of painful and scary coughing. Often, she cannot breathe during a coughing fit. She takes the prescribed medicines (Codeine, Albuterol, etc.), but still has frequent coughing episodes. Many years ago, she knew a physician on your staff who taught patients how to sit down, breathe,etc. in a way that would stop or prevent a violent coughing episode.
