Comparison of Clinical Status of Individuals With COPD and Preserved Ratio Impaired Spirometry

Despite the globally varying high prevalence rate of the PRISm phenotype, there are no guidelines for its diagnostic evaluation and management. Further studies are needed on appropriate approaches for individuals with PRISm to improve respiratory symptoms and prognosis. As research continues to evolve, PRISm needs to be recognized as a critical component of pulmonary assessments and at-risk individuals need to be provided with appropriate treatment and follow-up to prevent progression to COPD. There are no studies in the literature comparing PRISm, respiratory muscle strength, peripheral muscle strength and oxygenation, arterial stiffness, physical activity level and sleep level in COPD and healthy individuals. The aim of this study was to compare respiratory muscle strength, peripheral muscle strength and oxygenation, arterial stiffness, physical activity level and sleep level in PRISm, COPD and healthy subjects.
