Abstract

Objective: This study amied to investigated the rate of pulmonary ventilation disorders in patients after recovery from COVID-19. Method: A total of 111 patients after recovery from COVID-19 with no history of pulmonary disease went for regular health checks on lung ventilation function at Military Hospital 103, was recruited from February 2022 to May 2022. The patient's lung ventilation function is assessed by spirometry. Binary Logistic analysis was used to analyze the association between the presence of pulmonary ventilation disorder and the severity of illness during COVID-19 infection after adjusting for gender and time after infected COVID-19. Results: The proportion of patients with decreased FVC (%) and PEF (%) were 30.6% and 61.2%, respectively. The proportion of patients with a decrease in FEV1/FVC (%) and FEF 25-75% was 4.5%. An increased proportion of patients with decreased FVC (%) was observed in the group of patients with severe COVID-19 compared to the group of patients with mild COVID-19 (OR: 4.363, p < 0.05). Conclusion: These finidng indicates an increased rate of manifestations of ventilation disorders in patients after recovery from COVID-19.
