WebThe cough is an important defence mechanism for clearing excess secretions and foreign materials from airways [1,2].Generally, cough peak flows (CPFs) are measured using a spirometer or a peak flow meter to assess cough strength because cough strength reflects the ability to clear secretions from the respiratory tract and indicates the aspiration risk.
