Study to Assess the Effect of the Aerobika Device in Addition to Standard of Care Treatment in Sputum Producing COPD Patients Using FRI

Primary: The primary objective of this study is to evaluate the effect of the Aerobika® device on the aerosol deposition pattern of concomitant inhalation medication using FRI. Secondary: The secondary objective of this study is to evaluate the effect of the Aerobika® device on the airway volume (iVaw), lung and lobe volume (iVlobes), airway resistance (iRaw), hyperinflation, airway wall thickness (iVaww), blood vessel density (iVbv), and air trapping using FRI.
