In a retrospective analysis we observed that abnormal rv tlc ratio was a better predictor for obstruction.
Rv tlc is listed in the world s largest and most authoritative dictionary database of abbreviations and acronyms the free dictionary.
Tlc can be estimated.
This has practical applications in that a predicted tlc can be estimated from predicted fvc vc but is dependent on how well the predicted fvc fits the patient age height ethnicity etc as well as the assumption that rv tlc ratio is solely a function of age.
8 racial adjustment of predicted value most studies for normal values in us looked at caucasian populations of normals not apppp p g propriate for other ethnic groups if used in african american population more likely to seem abnormal 12 higher controversial.
Although the european respiratory society ers proposes using percentiles or standardized residuals for reporting results of lung volume measurements 1 this approach has not been widely accepted and percentages are still being used mainly because calculations and in.
A retrospective analysis of patients attending for static and dynamic volumes was undertaken.
Tlc is increased in copd particularly in the presence of emphysema where there is significant loss of elastic recoil resulting in lung hyperinflation.
Increases in rv and functional residual capacity may also be seen.
It is residual volume to total lung capacity ratio.
Functional residual capacity frc iis the point we breathe at and is the balance point between the chest wall and lung compliance.
