Abstract
The Forced Expiration Technique (FET), postural drainage (PD) and directed coughing were evaluated in 10 patients with copious sputum (mean value 63.3 ml/24 h) with an inhaled radioaerosol method over a 30-min treatment period. FET alone and FET + PD (but not directed coughing) cleared more radioaerosol than during the control period (P < 0.01). The wet weight of sputum obtained following FET, FET + PD and directed coughing were all significantly greater than control (P < 0.01). Sputum obtained by FET + PD was significantly greater than FET alone (P < 0.05). Both FET and particularly FET + PD were more effective than directed coughing alone and these maneuvers should be incorporated into standard chest physiotherapy.
