Description
Summary:Objective: Evaluate the spirometry pattern of patients who persisted with respiratory symptoms after infection with SARS-Cov-2. Methods: Cross-sectional, observational, retrospective study in a single center, approved by the local Ethics Committee (registration number: 5,120,720). Patients who underwent spirometry due to Post-Covid Syndrome were evaluated to analyze the spirometric pattern presented. The following were collected: exam identification data, sex, age, symptom time, the need for mechanical ventilation, and quality of spirometry, in addition to the following exam parameters: FVC, FEV1, FEV1/FVC, FEV 25-75/FVC, and FEV 75, evaluating the Lower Limit of Normality, pre-bronchodilator and post-bronchodilator values. Results: Data from 72 patients were collected. Of these, 55.5% of patients had spirometry results within normal limits. The most frequent respiratory alteration was obstructive respiratory disorder, present in 29.2% of the patients. Conclusions: The presence of dyspnea in patients with normal spirometry may indicate further evaluation of lung function and other etiologies for dyspnea.
