Flow-over-volume elevation (FOVE) on Spirometry Allows for Early Recognition of Usual Interstitial Pneumonia
While most patients with usual interstitial pneumonia (UIP) have reduced DLCO at the time of diagnosis, many have normal FEV1, FVC, and FEV1/FVC. Other PFT parameters representing increased lung stiffness and elastic recoil may allow earlier identification of UIP. This retrospective cohort study evaluated th...
