Brief Summary
Considering that respiratory physiotherapy lack scientific evidence to support its application in the treatment of several obstructive diseases, this investigation was designed to evaluate the hypothesis that Flutter Valve can improve the airway clearance of hypersecretive bronchiectasis patients.

Flutter Valve
EXPERIMENTALThis a crossover study, so all subjects performed both, control and experimental interventions. In Flutter Valve intervention the subjects remained comfortably seated, breathing through the device for 15 minutes, starting off from the total pulmonary capacity, and being free to cough. Thereafter, a 5-min session of cough ensued. In the control intervention the subjects followed the same sequence of the Flutter Valve intervention, but the metallic sphere and the cover of the device were removed. Since the patients were not acquainted with the valve, they did not know its proper assembly. As in the Flutter Valve intervention, during 15 minutes the patients could expectorate spontaneously and return to the device. A 5-min coughing session took place.
Interventions
Flutter Valve (Scandipharm, Birmingham, AL) is shaped like a pipe with a hardened plastic mouthpiece at one end, a plastic protective, perforated cover at the other end, and a high-density stainless steel ball resting in a plastic circular cone on the inside. When the patient expires, a vibratory effect is transmitted to airways by the steel ball oscillation in order to facilitate mucociliary clearance. In our study, the use of the equipment was guided by a registered physical therapist, but the position (angle) was determined by the patient, according to his/her adaptation and perception of effectiveness of sputum clearance. The patients remained comfortably seated, breathing through the device for 15 minutes, starting from the total pulmonary capacity, and being free to cough. Thereafter, a 5-minute session of cough was done.
