Abstract
Most spirometry errors reduce test results. The aim of the study was comparison results of spirometry performed with the ATS/ERS quantitative criteria and simple visual inspection criteria. 75 patients performed spirometry twice on the same day: according to criteria of the ATS/ERS quality for spirometry and on visual control. Statistical analysis was performed with Bland-Altman method. Forced expiratory volume (FVC) and forced expiratory volume in one second (FEV1) were greater for the cases with quantitative control. The mean difference between FVCs was 0.37 ± 0.29 L. The mean difference between FEV1s was 0.06 ± 0.2 L. Using ATS/ERS spirometry guide-lines may help improve results and avoids spirometry errors.
