Muscle Oxygenation in Patients With COPD Exacerbation

Chronic obstructive pulmonary disease (COPD) is often complicated by acute exacerbations, which lead to functional impairments, increased dyspnea, and a rapid decline in lung function. During an exacerbation, impaired pulmonary gas exchange, systemic inflammation, and increased work of breathing significantly alter oxygen availability and metabolic demand in skeletal muscles. The aim of this study is to evaluate and compare respiratory and peripheral muscle oxygenation in patients with acute exacerbation of COPD (AECOPD) and patients with clinically stable COPD. By examining these physiological changes, the study seeks to determine the impact of exacerbations on muscle function and oxygenation efficiency
