Brief Summary
Bronchiectasis is characterized pathologically by the abnormal and permanent dilation of bronchi caused mainly by the perpetuation of inflammation and impaired clearance of secretions. Physical therapy is essential in the treatment of these patients, using its various techniques and devices. The aim of this study is to evaluate the impedance of the respiratory system, by impulse oscillometry, after breathing exercises with chest compression or flutter in patients with bronchiectasis, considering that there are no results in the literature on the effect of these techniques in the small airways of these patients.

Outcome Measures
Primary Outcomes (3)
Respiratory System Impedance
Will be evaluated the resistance (R), reactance (X), reactance area (AX) and resonance frequency (Fres) before, immediately after the intervention and after 30 minutes of rest in order of identifying changes in the components of resistance of airways of individuals.
In the primary evaluation, and after seven and fourteen days.
Difficulty sputum
Patients inform the ease or difficulty in expectoration in accordance with a scale of 1 to 5, where 1 = no difficulty and 5 = extremely difficult. (Burioka, 1998). The scale will be applied at baseline and always after the intervention to assess whether there is difference in the difficulty of sputum between sessions.
In the primary evaluation, and after seven and fourteen days.
Secretions weight
The secretions are collected in the universal and heavy collectors on a precision balance.They will be evaluated in the total weight measurements and a dry weight and wet mucus. The weight of mucus of each interventions are compared to determine a technique with improved efficiency for removal of secretions.
In the primary evaluation, and after seven and fourteen days.
Secondary Outcomes (4)
Pulse oximetry
In the primary evaluation, and after seven and fourteen days.
Acceptability and tolerance
In the primary evaluation, and after seven and fourteen days.
Dyspnea scale:
In the primary evaluation, and after seven and fourteen days.
Adhesiveness of expectorated secretion:
In the primary evaluation, and after seven and fourteen days.
Study Arms (3)
Flutter Intervention
ACTIVE COMPARATORAfter initial evaluation, the subjects will perform breathing exercises with quiet inspiration and prolonged expiration on the device for thirty minutes, with breaks of one minute every four minutes. Immediately after the exercise will be performed new assessment against Impulse Oscillometry. Then patients will be kept for 30 minutes at rest and at the end will be applied the acceptability and tolerance scale and a third evaluation with Impulse Oscillometry. The secretions expectorated during the protocol will be evaluated for weight, adhesiveness and purulence.
Chest Compression Intervention
ACTIVE COMPARATORAfter initial evaluation, the subjects will be instructed to perform deep breaths between three quiet inspiration brought, and expiration will be accompanied by bilateral compression with the therapist's hands on the lower ribs during thirty minutes with one minute intervals of rest every four minutes. Immediately after the exercise will be performed new assessment against Impulse Oscillometry. Then patients will be kept for 30 minutes at rest and at the end will be applied the acceptability and tolerance scale and a third evaluation with Impulse Oscillometry. The secretions expectorated during the protocol will be evaluated for weight, adhesiveness and purulence.
Crontrol Intervention
ACTIVE COMPARATORAfter initial evaluation, patients will be remain seated quiet breathing without any guidance for thirty minutes. Immediately after this time will be held reassessment with Impulse Oscillometry. Then patients will be kept for 30 minutes at rest and at the end will be applied to acceptance and tolerance scale and a third evaluation with Impulse Oscillometry. The secretions expectorated during the protocol will be evaluated for wight, adhesiveness and purulence.
Interventions
Flutter is a small device, simple, like a plastic pipe with a mouthpiece at one end and a perforated cover on the other, containing a steel ball resting in a plastic cone inside. When the patient exhales through the flutter expiratory flow causes movement of the ball, creating an oscillatory positive pressure.
Manual chest compression is based on the application of forces resulting from the action of respiratory muscles or physiotherapist manual action in order to increase the alveolar pressure creating a pressure gradient to promote change in pulmonary flow and volume.It consists of vigorous compression of the chest at the beginning of expiration or during expiration.
For this measure will be used IOS Jaeger (Jaeger, Wurzburg, Germany). to minimize the effect of the bad positioning of the tongue will use a mouth "free-flow", which contains a depressant for keeping the tongue in the mouth soil, stabilizing it and reducing oral resistance. Volunteers will support hands firmly on the cheeks to reduce the effect of oscillation thereof. The measures will be carried out with the volunteer sitting, using nasal, relaxed and your head in neutral clip, breathing normally through the mouthpiece to his lips tightly sealed to prevent air leaks.
Dyspnea will be evaluated across the range Medical Research Council (MRC) for use in patients with chronic obstructive pulmonary disease in Brazil.
patients will complete scales 1-7, 1: extremely and 7: none) on usefulness, ease to understand the instructions, easy to perform the exercises, degree of fatigue and discomfort
During therapy the patient will remain monitored with digital oximeter and the information will be recorded before and after the procedures
Patients inform the ease or difficulty sputum according to a scale of 1 to 5, where 1 = no difficulty and 5 = extremely difficult.
