ClinConnect Summary
Bronchiectasis patients and healthy subjects will be evaluated before and after a 30 minutes session of control, breathing exercises with flutter valve, that is a device that produces oscillation and positive pressure during the expiratory phase, or chest compression, that is a manual manoeuvre in the right and left sides of the lower chest, all of them in a sitting position. The main outcome will be obtained by impulse oscillometry, that is a method to access large and small airways, to evaluate the resistance (R), reactance (X), reactance area (AX) and resonant frequency (Fres) of respira...
