Abstract: Preserved ratio impaired spirometry (PRISm) is a pulmonary function pattern characterized by a forced expiratory volume in one second (FEV1) to forced vital capacity ratio greater than 0.70, ...

Measures of pulmonary function, such as FEV 1 and FEV 1 /FVC ratio, are important predictors of population morbidity and mortality 1,2,3,4 as well as forming the basis for the diagnosis of COPD. It is ...

Recent studies show that many patients are being treated for COPD without confirmatory spirometry. In-office testing is easy and available. A recent study showed that only 32% of patients admitted to ...

Good technique is essential when undertaking spirometry tests, and correct interpretation of the results is important to avoid making an incorrect diagnosis. Lung function results are reported as ...

The guideline-recommended FEV1:FVC value of less than 0.70 is the optimal cutoff for the diagnosis of clinically significant chronic obstructive pulmonary disease (COPD), researchers say. The study, ...
