A gradual lung disease known as chronic obstructive pulmonary disease (COPD) contains emphysema, severe asthma, and bronchiolitis. Breathlessness, prevalent coughing, gasping for breath, and tightness of the chest are all signs of COPD. Despite the fact that the disorder is potentially reversible, there are therapies for COPD symptoms. The 6-minute walk test (6MWT) is frequently used by doctors to assess lung health and gauge how well a treatment is working. It's a simple, painless way to gauge how your body reacts to exercise. In this article, we put forth a hypothesis regarding the impact of bubble PEP on 6MWD for assessment of functional capacity in COPD patients who are hospitalized.Sample collection methods were used to collect the data. Data on nearly 174 patients, including both genders, was gathered, and three groups were made based on grade and severity. Various tests have been applied to the data in the vast experimental analysis, and the outcomes of the various tests have been correlated. Finally, a variety of tests demonstrate a set of variables and their favorable or unfavorable impact on COPD
