A comparison of alternative selection methods for reporting spirometric parameters in healthy adults.

ABSTRACT: Alternative methods have been proposed to report spirometry indices from test sessions (forced expiratory volume 1 s, FEV₁; forced vital capacity, FVC). However, most use the American and European Societies' standard (ATS/ERS) which stops sessions once a repeatability threshold is met which may not accurately represent intra-session variability. Our goal was to repeat trials beyond the repeatability threshold and evaluate alternative reporting methods. 130 adults performed spirometry across two visits. Spirometry indices were reported using the ATS/ERS standard and four alternatives. 78 participants (60%) had valid data for all methods and visits. Intra-session coefficients of variation were low (FEV₁: 3.1-3.7%; FVC: 2.3-2.8%). Our four alternative methods yielded FEV
