inter- and intra- device variability of pulmonary function testing across vitalolab systems

Abstract P63 evaluated inter- and intra-device variability of pulmonary function testing across two identical VitaloLAB PFT systems. The devices were used to perform spirometry, diffusing capacity (DLCO), and lung volume (MBN₂ washout) testing, demonstrating low variability and strong comparability of results between systems.
