Novel Pulmonary Function Parameter Shifts in High-Grade Upper Airway Stenoses.
In conclusion, the elevation of RV/TLC with concomitant normal FEV1/VC in symptomatic patients could be used to demarcate rare UAS from common OPD. Moreover, RV-TLC ratio might be used to distinguish between low- and high-grade UAS. But further epidemiological studies will be necessary to validate these findings. Level of evidence: 4.
