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, ...

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, ...

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 ...

Research published in Thorax indicates that use of a lower limit of normal (LLN) spirometric threshold fails to identify a number of patients with airflow obstruction and chronic obstructive pulmonary ...
