Preserved ratio impaired spirometry (PRISm) was associated with the development of airway obstruction over 10 years of follow-up, independent of smoking habits, with comparable odds for disease ...

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, ...

"Physicians should feel more confident in following the recent guideline recommendations both to use race-neutral reference equations and to use z scores for assessing severity…Together, these changes ...

The recent statement on interpretive strategies for lung testing uses the acronym PRISm for preserved ratio impaired spirometry. PRISm identifies patients with a normal forced expiratory volume in 1 ...

A race-specific approach to spirometry interpretation results in a lower lung allocation score (LAS) for Black patients and a higher LAS for White patients, according to a study published online May ...
