Oscillometry in the COPD Exacerbator Phenotype With Triple Inhaled Therapy Study

The objective of this observational study is to determine the effectiveness of inhaled corticosteroids in patients with chronic obstructive pulmonary disease (COPD) and frequent worsening of their respiratory symptoms by using a device called an oscillometer. This instrument is capable of measuring bronchial obstruction and air trapping in the lungs through vibrations during normal breathing. The main question it seeks to answer is: Could oscillometry be useful in assessing the effectiveness of inhaled corticosteroids in patients with COPD exacerbations, in terms of bronchial obstruction and air trapping in the lungs? Patients who choose to participate will undergo oscillometry testing and complete standard COPD questionnaires during three follow-up visits spread over three months.
