Hyperinflation

The purpose of the study is to evaluate the effect of BGF MDI compared with placebo MDI on cardiac and lung function when administered in participants diagnosed with COPD and hyperinflation.

The goal of this clinical trial is to investigate the effects of elastic chest compression on functional exercise capacity and respiratory performance of patients with COPD. The main questions it aims to answer are: Is there difference in functional exercise capacity and respiratory performance without or with the use of elastic upper chest compression? Is there difference in functional exercise capacity and respiratory performance between the use of elastic upper chest compression and elastic lower chest compression? Participants will: Be evaluated under three conditions on three different days: without elastic compression, with upper chest compression, and with lower chest compression, with the order of compression application randomly assigned. The functional capacity and respiratory muscle performance of all patients will be evaluated. The days for evaluation will be at least three days apart from each other.
