PULMONARY REHABILITATION IN POST-COVID-19 SYNDROME

Abstract

Post-COVID-19 syndrome represents a complex clinical entity characterized by the persistence of symptoms for at least two months after the initial SARS-CoV-2 infection. This multisystemic condition involves pulmonary, cardiovascular, neurological, and psychological dysfunctions, generating a significant impact on patients' quality of life. The present article examines the pathogenic mechanisms involved, including immune dysregulation, viral persistence, intestinal dysbiosis, and endothelial dysfunction. Diagnostic modalities and symptom severity assessment are also presented, with emphasis on the importance of pulmonary function tests, exercise capacity evaluation, and quality of life assessment. Pulmonary rehabilitation, as the cornerstone in the management of post-COVID-19 syndrome, is detailed, highlighting the role of physical training, breathing techniques, and multidisciplinary support. In addition, specific aspects of post-COVID-19 interstitial lung disease (PC-ILD) and related therapeutic strategies are discussed. The article highlights the need for an individualized approach and careful monitoring of patients to optimize outcomes and improve prognosis.
