Elevated RV/TLC ratio

Finding
Synonyms: Hyperinflation on pulmonary function test; Overinflation on pulmonary function test
 
HPO: HP:0033240

Definition

An increase in the ratio of residual volume (RV) to total lung capacity (TLC) on pulmonary function testing. RV is the amount of air remaining aftermaximal expiration and TLC is the total amount of air in theungs at full inspiration. These volumes cannot be determined by spirometry, but can be measured by inert gas dilution, nitrogen washout, and (3) body plethysmography. An elevated RV/TLC can be interpreted as a sign of air trapping and hyperinflation. [from HPO]
