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, ...

Researchers say that using the lower limit of normal (LLN) of the forced expiration volume in 1 second (FEV1)/forced vital capacity (FVC) ratio improves risk stratification in patients with chronic ...

Bronchiolitis obliterans syndrome (BOS) is a serious complication of chronic GVHD (cGVHD) following HSCT (hematopoietic SCT). The clinical diagnosis of BOS is based on pulmonary function test (PFT) ...

Spirometry is a standard test doctors use to determine how well your lungs function. A score that measures airflow into and out of your lungs can help diagnose COPD and determine the best treatments.

Spirometry test There is significant disparity in the ratios for postbronchodilator FEV1/FEV6 and FEV1/FVC %, and this disparity is very pronounced in women. Disclosure: One study author declared ...

In a large US cohort study, pre-pandemic severe obstructive lung function, as measured by spirometry, was linked to more than a twofold increased risk for severe COVID-19. Researchers analyzed the ...

Preserved ratio impaired spirometry (PRISm) was associated with increased odds of interstitial lung abnormalities (ILAs), and having both PRISm and ILAs was linked to a higher risk for mortality than ...
