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.

DEVICE

Flutter Valve

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.
