    AbstractThe study was designed to ascertain the movement of mucus from proximal and peripheral regions within the human lungs during cough and the forced expiration technique (FET). Mucus movement was measured using a radioaerosol technique. Seven patients (mean +/- SEM age: 63 +/- 3 years) with airways obstruction (% predicted FEV1: 44 +/- 4) participated in the study. Each patient underwent three assessments in a randomized manner: control/cough/FET. Peak expiratory flow rate (PEFR) was measured at the mouth during cough and FET. None of the patients produced sputum during the assessment periods. Both cough and FET compared with control increased, on average, mucus clearance from all regions; statistical significance was achieved only for central lung regions with cough (P less than 0.05). There was no significant correlation between PEFR during cough/FET and regional lung clearance.
