Background: Most COVID-19 patients recover without hospitalization, although a significant percentage needs hospitalization for pneumonia and other sequelae. Corona viral disease-19 (COVID-19) targets the lung, however its effects on lung function are unknown. Objective: This analysis aims to explore the significance of Spirometry in evaluating lung function in individuals who have recovered from COVID-19 and developed pneumonia. Materials and Methods: Prospective observational study conducted in the Department of Pulmonary Medicine, Gazi Medical College (GMC), Khulna, Bangladesh, during May 2021 to June 2022, to find out lung function assessment of post-COVID-19 recovered pneumonia cases after 12 weeks of discharge from hospital. Total 50 cases were enrolled in study after IRB approval and written informed consent of patient. Results: A restrictive pattern was observed in 43.6% of the patients, while 21.8% had normal lung function, 14.7% had obstructive patterns, and 19.9% displayed mixed patterns. In the abnormal lung function group, a majority of patients (60.7%) were aged 50 years or older. In the normal lung function group, a single patient (2.9%) exhibited an oxygen saturation level below 75%, but in the abnormal lung function group, 34 patients (27.9%) demonstrated the same. There was a statistically significant difference (p<0.05) seen between the two groups. Conclusion: Age above 50 years, male gender, Diabetes mellitus, High CT severity, longer duration of illness, proper timing of initiation of BIPAP/NIV therapy, has documented significant impact on post- COVID lung functions.
