WebApr 11, 2024 · The functional lung assessment (PFT) was as follows. Initial evaluation performed within six months after initial visit included: forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC, diffusing capacity for the lungs measured using carbon monoxide (DLCO), total lung capacity (TLC) and residual … WebDLCO is measured by sampling end-expiratory gas for carbon monoxide (CO) after patients inspire a small amount of carbon monoxide, hold their breath, and exhale. Measured DLCO should be adjusted for alveolar volume (which is estimated from dilution of helium ) and the patient’s hematocrit. DLCO is reported as mL/minute/mm Hg and as a ...
WebWe retrospectively analyzed the pulmonary function records of all patients who had measurement of their diffusing capacity and 6-min walk oximetry in our university pulmonary function laboratory over a 2-year period. Results: The median DLCO was 51% predicted and the median DLCO/VA was 64% predicted. WebLung diffusion testing measures how well your lungs do this back-and-forth exchange.
