To study the pulmonary function changes in post-COVID-19 discharged patients and their correlation with disease severity

The study aimed to assess pulmonary function changes in post-COVID-19 discharged patients and their correlation with disease severity. A single-center, hospital-based, observational, cross-sectional study was conducted on ICMR laboratory-confirmed non-critical COVID-19 cases. The study assessed pulmonary function using EasyOne® Air with TrueFlow™ Technology at one-month and three-month intervals after clinical recovery. Results showed that moderate and severe cases had significant pulmonary function impairments. Notably, 43.8 of mild cases and 68.8 of moderate cases demonstrated improved outcomes. The study highlights the importance of monitoring pulmonary function in post-COVID–19 patients for appropriate management and rehabilitation.
