Around 20% to 25% of individuals with rapidly declining FEV1/FVC trajectories experienced wheezing and usual ...

Participants with higher forced vital capacity, indicating better lung function, were less likely to develop heart disease, diabetes, and stroke over 10 years.

"Additionally, men experienced a 17% reduced risk of airway obstruction. In women, while higher hemoglobin levels were linked ...

The test can help determine COPD staging. Depending on your FEV1 and FVC readings, your doctor will stage your COPD based on the following: The first stage is considered mild.Your FEV1 is equal to ...

We used forced vital capacity (FVC), forced expiratory volume 1st second (FEV1) and the ratio of FEV1 to FVC to analyze the effects of Se intake and asthma on pulmonary function. Current ...

A ratio of your FEV1/FVC needs to be less than 0.7 for a diagnosis of COPD. Doctors grade your spirometry results from grade 1 (least severe) to grade 4 (most severe). In the old system ...

Spirometry was performed at baseline and at follow-up, with incident COPD defined using a lower limit of normal criterion for postbronchodilator FEV1/FVC. Only participants without COPD and without ...

Further methodological details can be found in our previous publication (16). Using the pulmonary function parameters from the NHANES SPX dataset, we collected FEV1 and FVC as primary indicators and ...

“This investigation was particularly relevant given the higher prevalence of COPD in older age groups and the potential risks associated with overdiagnosis, such as unnecessary medication use and ...

Introduction Chronic obstructive pulmonary disease (COPD) is a major global health issue characterized by significant morbidity and mortality. It can result from impaired lung function development ...
